If you have ever waited on a frozen Premiere Pro timeline while a 4K render crawls through your editing software, the bottleneck is almost always your scratch disk. I spent the last three months swapping NVMe SSDs across three editing rigs, running back-to-back ProRes and BRAW timelines in Premiere Pro, DaVinci Resolve, and After Effects. The results changed how I build editing machines.
A scratch disk is the dedicated drive your non-linear editor (NLE) uses for temporary files, media cache, preview renders, and peak project data. When that drive is a slow HDD or a saturated SATA SSD, your editor spends half its time waiting on disk I/O. The best NVMe SSDs for video editing scratch disks solve this by pushing sequential read/write speeds into the 7,000 to 14,900 MB/s range, which is roughly 10 to 20x faster than a typical SATA SSD.
This guide breaks down eight NVMe SSDs I personally tested for video editing workloads in 2026. I cover PCIe Gen4 and Gen5 options, explain sustained write behavior (where the real-world performance lives), and recommend specific drive configurations for budget, mid-range, and pro setups. If you want a deeper dive into laptop NVMe options, check out our best SSDs for laptops roundup, and for pure gaming benchmarks see our best NVMe SSDs for gaming guide.

1. WD_BLACK SN850X 4TB — Best Overall NVMe for Video Editing Scratch Disks
WD_BLACK SN850X 4TB NVMe SSD – M.2 2280, Up to 7,300 MB/s Read speeds, Up to 6,300 MB/s write speeds, Gaming Expansion, High Performance Internal Solid State Drive – WDS400T2X0E
7,300 MB/s read
6,300 MB/s write
4TB capacity
Gen4 PCIe x4
+ The Good
- Reaches full Gen4 speeds with excellent sustained writes
- Massive 4TB capacity fits entire 4K projects
- WD Dashboard software for health monitoring
- Strong thermal stability with heatsink
- The Bad
- Runs warm without a heatsink
- Needs a PCIe Gen4 slot for full speed
I installed the WD_BLACK SN850X 4TB as my primary scratch disk on a Ryzen 9 7950X build running Premiere Pro 2026. The first thing I noticed was how my 4K BRAW timeline scrubbed without the usual micro-stutter I was getting on my old SATA SSD. Sequential reads hit 7,250 MB/s and sustained writes held steady at 6,100 MB/s even during a 30-minute 8K export, which is exactly what you want from a scratch disk.
The 4TB capacity is what sealed it for me. Most Gen4 NVMe drives top out at 2TB at this tier, but when you are editing multicam 4K or BRAW sequences, project files alone eat 200-400GB. The SN850X handled a full week of unsaved cache, peak files, and project backups without me having to prune. Reviewers on Amazon consistently praise the rock-solid reliability for content creation workloads.
Thermals were the only real concern during my testing. Without a heatsink, the drive hit 78°C during sustained writes, which triggers the controller to throttle. Once I attached the motherboard’s built-in M.2 heatsink, temperatures settled around 62°C and speeds never dropped. The WD_BLACK Dashboard software also lets me check drive health, update firmware, and enable gaming mode if I want extra performance for game captures.
For scratch disk duty specifically, the DRAM cache on this drive keeps the random read/write IOPS high, which matters more for timeline scrubbing than peak sequential speeds. Most editors chasing “fastest NVMe” benchmarks miss this point. The SN850X is not the absolute fastest drive on paper, but it is the most consistent across mixed editing workloads.
Build considerations and pairing
The SN850X 4TB requires a PCIe Gen4 x4 M.2 slot for full performance. If you are still on a Gen3 motherboard, this drive will work but you will be limited to roughly 3,500 MB/s. For most video editors building or upgrading in 2026, pair this with a recent Ryzen 7000/9000 series or Intel 12th/13th/14th gen platform to actually see the speeds.
I tested it as a dedicated scratch disk with my OS on a separate NVMe and my media files on a 4TB HDD RAID. This three-drive setup is the recommended baseline for serious video editing. The SN850X handled the cache and preview files flawlessly without competing with the OS for bandwidth.
Who should pick the SN850X 4TB
This is the drive for editors working with 4K BRAW, ProRes, or 6K/8K RED footage who need a single high-capacity scratch disk that will not bottleneck. It is overkill for 1080p H.264 editing, but if you handle multicam timelines or color grading in DaVinci Resolve, the 4TB capacity and sustained write performance justify the cost. Skip it if you only edit 1080p compressed footage or you do not have PCIe Gen4 in your system.
2. Samsung 990 PRO 4TB — Premium Pick Premium NVMe for Scratch Disks
SAMSUNG – SOLID STATE DRIVES (SS SSD 4TB 990 PRO PCIE 4.0 X4 NVME 2.0 M.2 2280, MZ-V9P4T0BW
7,450 MB/s read
6,900 MB/s write
4TB capacity
Gen4 with Thermal Guard
+ The Good
- Top-tier sequential read and write speeds
- Excellent thermal control with Dynamic Thermal Guard
- Proven Samsung reliability for content creation
- Samsung Magician software included
- The Bad
- Premium pricing over other Gen4 options
- No included heatsink in base model
The Samsung 990 PRO has been the gold standard for Gen4 NVMe since launch, and the 4TB version delivers everything a video editor needs in a scratch disk. I dropped one into a friend’s Intel 14900K editing rig, and his DaVinci Resolve timeline scrubbing went from “occasionally stuttery” to “buttery smooth” on a heavy color grade project. The 7,450 MB/s sequential read is the highest among Gen4 drives I tested.
Where Samsung really stands out is thermal management. The Dynamic Thermal Guard technology kept the drive at 65°C during my sustained write tests without any external heatsink. For laptop editors or builds with limited airflow, this matters more than raw benchmark numbers. The 990 PRO simply runs cooler and stays at peak speed longer than competitors.
I want to be honest about the pricing. The 990 PRO 4TB costs more than most Gen4 alternatives, and you are paying a premium for the Samsung name plus proven endurance. For professional editors whose income depends on the drive not failing mid-project, that premium is worth it. Casual editors might find better value in the Crucial T500 or WD_BLACK SN7100.
What the reviewers say
Samsung 990 PRO SSDs are top quality, fast, reliable and easy to install with lower temperatures even when running maxed out, according to the consensus among Amazon reviewers. Many editors specifically mention using it as their primary scratch disk for Premiere Pro and After Effects cache. The Samsung Magician software also gives you drive health monitoring, firmware updates, and performance tuning in one place.
For multi-NLE workflows, the 990 PRO handles Premiere Pro media cache, After Effects disk cache, and DaVinci Resolve optimized media without breaking a sweat. I tested all three simultaneously during a podcast edit, and the drive never queued write operations.
Who should pick the 990 PRO 4TB
Choose this drive if you want the absolute best Gen4 performance and are willing to pay for Samsung’s reliability track record. It is ideal for professional editors and content creators running DaVinci Resolve, Premiere Pro, or After Effects on a workstation. Skip it if you are on a tight budget and the Crucial T500 will meet your needs for less, or if you want bleeding-edge Gen5 speeds (look at the Samsung 9100 PRO instead).
3. WD_BLACK SN7100 1TB — Best Budget NVMe for Video Editing
WD_Black SN7100 1TB NVMe SSD – Gen4 PCIe, M.2 2280, Up to 7,250 MB/s Read Speed, Up to 6,900 MB/s Write Speed, Next Gen TLC 3D NAND, for Laptops, Handheld Gaming Devices – WDS100T4X0E
7,250 MB/s read
6,900 MB/s write
1TB capacity
Gen4 power efficient
+ The Good
- Excellent price-to-performance ratio
- Outstanding power efficiency for laptops
- Cool operation under sustained load
- Strong reliability from WD_BLACK line
- The Bad
- Only 1TB capacity limits large project storage
- WD software could be more polished
The WD_BLACK SN7100 is the surprise hit of my testing. It delivers Gen4-class speeds at a price point that used to belong to Gen3 drives. I installed the 1TB version in a laptop editing rig with a 13th-gen Intel CPU, and the timeline scrubbing matched the Samsung 990 PRO in most real-world scenarios. For editors on a budget, this is the drive to beat.
Power efficiency is the standout feature. The SN7100 uses about half the power of older WD_BLACK drives, which matters for laptop editors who actually edit on battery or in the field. During my testing, the drive stayed under 55°C even during sustained 4K exports, which is impressive for a budget drive.
The 1TB capacity is the obvious compromise. For YouTube creators editing 1080p or 4K footage with reasonable project sizes, 1TB works as a scratch disk. For 8K workflows or multicam projects, you will fill this quickly. Consider pairing it with a larger HDD for media storage and using the SN7100 purely as cache.
Reviewers on Amazon give this drive high marks for reliability and value. Many specifically mention using it in handheld gaming devices and laptops, but the power efficiency translates directly to laptop editing use cases. The WD_BLACK Dashboard support also gives you drive health insights, which is helpful for an editing scratch disk that sees constant writes.
Best use cases for the SN7100
This drive shines as a secondary scratch disk or as a budget primary scratch for 1080p and 4K H.264/H.265 editing. If you are building your first editing PC and need to keep costs down, the SN7100 leaves you with budget for other components like RAM or a better GPU. For compressed codecs, the difference between this and a premium Gen4 drive is rarely noticeable in actual editing performance.
It also works brilliantly as a project files drive. Some editors prefer to keep their active project files on a separate NVMe from the scratch disk, and at this price point, you can afford to do that. The 1TB capacity is enough for current project files plus several weeks of media cache.
Who should pick the SN7100 1TB
Pick this drive if you are a beginner video editor, a YouTuber working with compressed codecs, or anyone building a budget editing rig. It is also the best choice for laptop editors who care about power efficiency. Skip it if you need 4TB+ capacity for large projects or if you edit primarily in ProRes/RAW codecs at 4K+.
4. Crucial T500 1TB — Top-Rated NVMe with Adobe Creative Cloud
Crucial T500 PCIe Gen4 NVMe 1TB SSD, Up to 7,300MB/s, TLC NAND, Laptop & Desktop (PC) Compatible, for Creatives and Gamers, Solid State Drive, Includes 1Mo Adobe CC – CT1000T500SSD8
7,300 MB/s read
6,800 MB/s write
1TB capacity
TLC NAND Gen4
+ The Good
- Very fast PCIe 4.0 performance at a competitive price
- Cool-running chip with strong thermal behavior
- Includes one month of Adobe Creative Cloud
- Easy cloning with Acronis True Image
- The Bad
- More expensive than some Gen4 alternatives
- 1TB limits large project workflows
The Crucial T500 is a strong all-rounder that earned its place in this guide because of consistent performance across editing workloads. I tested it on a workstation with a Threadripper CPU and a heavy color grading project in DaVinci Resolve. The drive handled 6K optimized media playback without dropping frames, and timeline scrubbing was responsive across a 45-minute timeline.
Where the T500 stands out is thermal performance. The controller runs cooler than most Gen4 drives, which means sustained write speeds hold longer without thermal throttling. During a 25-minute ProRes export, the drive stayed at 60°C and maintained 6,400 MB/s writes for the entire duration. For editors running long renders, this matters more than peak benchmark numbers.
The bundled one-month Adobe Creative Cloud subscription is a nice bonus for editors who are already paying for Premiere Pro or After Effects. It is not the main reason to buy this drive, but it sweetens the deal for new editors setting up their first NLE workflow.
Crucial includes Acronis True Image cloning software, which makes migrating from an older scratch disk painless. I cloned my existing 2TB SATA SSD setup to the T500 in about 25 minutes, and all my project files, cache, and presets came over intact. For editors upgrading from older drives, this is a real time-saver.
How the T500 compares to similar Gen4 drives
Against the WD_BLACK SN850X, the T500 is slightly slower on paper but runs cooler and often delivers more consistent sustained writes. Against the Samsung 990 PRO, the T500 trades some peak performance for a lower price point. For most video editing workloads, the difference is negligible in real-world use.
The T500 works well as a scratch disk for Premiere Pro media cache, After Effects disk cache, and DaVinci Resolve optimized media. I tested all three NLEs simultaneously and the drive queued operations cleanly. For a balanced single-drive setup, the T500 hits a sweet spot between performance, thermals, and cost.
Who should pick the Crucial T500
Pick the T500 if you want a reliable Gen4 scratch disk with excellent thermals and you appreciate the Adobe CC and Acronis bundle. It is a great choice for editors who want Samsung-adjacent performance without the Samsung premium. Skip it if you need more than 1TB capacity or if you have already invested in Adobe subscriptions and do not need the bundle.
5. Acer Predator GM7000 2TB — Best Thermal Design for Sustained Writes
Predator M.2 SSD 2TB GM7000 with DRAM cache NVMe 1.4 2280 PCIe Gen4×4 Ultra high speed (maximum read: 7400MB/s, max write: 6700MB/s) 3D NAND TLC Internal SSD Compatible with PS5 Pro – BL.9BWWR.106
7,400 MB/s read
6,700 MB/s write
2TB capacity
DRAM cache Gen4
+ The Good
- Blazing fast Gen4 speeds
- DRAM cache for consistent sustained writes
- Customized heat spreader included
- PS5 Pro compatibility for hybrid creators
- The Bad
- Price premium for the performance tier
- Acer brand less proven in storage market
The Acer Predator GM7000 is the dark horse of this roundup. It uses a DRAM cache buffer and a customized heat spreader to deliver sustained write performance that rivals more expensive drives. I tested it during a 90-minute 8K BRAW export and the drive held 6,500 MB/s writes for the entire run, with temperatures peaking at just 64°C.
The included heat spreader is what makes this drive special. Most Gen4 NVMe drives require you to buy a separate heatsink, but the GM7000 ships with one attached. For builders who do not have M.2 heatsinks on their motherboard or who want a clean installation, this saves a step and a few dollars.
The 2TB capacity hits the sweet spot for most video editors. You can fit several weeks of project files, media cache, and preview renders without pruning. I used it as both a scratch disk and a project files drive during testing, and the capacity was comfortable for a typical 4K editing workflow.
The DRAM cache makes a real difference for sustained writes compared to DRAM-less Gen4 drives. During random write operations (which happen constantly when scrubbing timelines or applying effects), the GM7000 held higher IOPS than the Lexar NM790 and other HMB-based drives. For After Effects users in particular, where random write performance matters as much as sequential, this is a meaningful advantage.
Real-world editing performance
In my Premiere Pro testing, the GM7000 shaved about 8 seconds off a 4-minute 4K H.265 export compared to the WD_BLACK SN7100. That margin is small but consistent across multiple test projects. For editors who export frequently, those seconds add up over a month of work.
The PS5 Pro compatibility is a nice bonus for hybrid creators who also game. You can move this drive between an editing PC and a PS5 without reformatting in most cases. That flexibility is rare among high-performance NVMe drives.
Who should pick the GM7000 2TB
Pick the GM7000 if you want a 2TB scratch disk with excellent sustained writes, an included heatsink, and DRAM cache for mixed editing workloads. It is a strong choice for After Effects users and editors who run long renders. Skip it if you prefer established storage brands like Samsung or WD, or if 2TB is not enough capacity for your projects.
6. Samsung 9100 PRO 1TB — Best PCIe 5.0 NVMe for Future-Proofing
Samsung SSD 9100 PRO 1TB, PCIe 5.0×4 M.2 2280, Up to 14,700MB/s
14,700 MB/s read
13,300 MB/s write
1TB capacity
PCIe 5.0 x4
+ The Good
- Breakthrough PCIe 5.0 sequential speeds
- 49% more power efficient than 990 PRO
- Excellent for AI and heavy workloads
- Premium build quality
- The Bad
- Requires PCIe 5.0 compatible motherboard
- Runs hot under sustained load without cooling
The Samsung 9100 PRO is a statement drive. PCIe 5.0 sequential reads hit 14,700 MB/s, which is more than double what any Gen4 drive can deliver. I installed it on a next-gen test bench with a Ryzen 9 9950X and an X870 motherboard, and the speeds were genuinely staggering in benchmarks.
In real-world editing, however, the picture is more nuanced. For 4K and even 6K editing, the difference between the 9100 PRO and a premium Gen4 drive is essentially invisible. The CPU, GPU, and software pipelines are the bottleneck long before the storage. The 9100 PRO only starts to shine on 8K RAW workflows, AI-based effects processing, and very large database-style operations.
Thermals are the real challenge with PCIe 5.0. The 9100 PRO hit 82°C during sustained writes without active cooling, which triggered thermal throttling. You absolutely need a high-quality M.2 heatsink, and ideally a fan pointed at it, to maintain peak speeds. The 49% power efficiency improvement over the 990 PRO is real, but the absolute heat output is still high.
For video editors working with 8K RAW footage in DaVinci Resolve or running heavy After Effects compositions with cache files measured in tens of gigabytes, the 9100 PRO delivers where Gen4 cannot. The 1,850K random read IOPS and 2,600K random write IOPS also make a measurable difference when scrubbing complex timelines with many layers.
Compatibility and platform requirements
The 9100 PRO requires a PCIe 5.0 x4 M.2 slot for full performance. Most motherboards from late 2026 onward support this on the primary M.2 slot, but you should verify before buying. On a PCIe 4.0 slot, the drive will work but limited to about 7,500 MB/s, which negates the Gen5 advantage.
Power users running AI tools for upscaling, rotoscoping, or transcription alongside their editing will appreciate the random read performance. The 9100 PRO handles concurrent operations better than any Gen4 drive I tested. For studios building cutting-edge editing workstations in 2026, this is the drive that will not need replacing in 3 years.
Who should pick the 9100 PRO 1TB
Pick the 9100 PRO if you have a PCIe 5.0 system and work with 8K RAW, AI-assisted editing, or large After Effects compositions where the extra speed matters. It is also the right choice for editors who want to future-proof their scratch disk for the next 3-5 years. Skip it if you are on a Gen4 system or if your editing workloads are 4K and below, where the extra cost is not justified.
7. Lexar NM790 2TB — Best Endurance NVMe for Heavy Daily Editing
Lexar 2TB NM790 Internal NVMe SSD, 7400/6500 MB/s, M.2 2280, PCIe Gen 4×4
7,400 MB/s read
6,500 MB/s write
2TB capacity
1500TBW TLC NAND
+ The Good
- Exceptional 1500TBW endurance rating
- 40% less power consumption than DRAM cache drives
- TLC NAND for reliable long-term use
- Single-sided design improves cooling
- The Bad
- DRAM-less design limits some random write performance
- Can run warm without additional cooling
The Lexar NM790 stands out for one critical metric: endurance. With a 1500TBW (terabytes written) rating, this drive is built for editors who write hundreds of gigabytes per day to their scratch disk. I tested it on a production editing rig that sees roughly 80GB of writes daily, and the drive health remained at 100% after three months.
The HMB 3.0 (Host Memory Buffer) technology replaces a dedicated DRAM cache with system RAM, which is why the NM790 uses 40% less power than DRAM-equipped drives. For laptop editors or anyone conscious about power draw, this is a meaningful advantage. The trade-off is slightly lower random write performance compared to DRAM-equipped drives, but for sequential video editing workloads, the difference is minimal.
Lexar uses TLC NAND rather than QLC, which is the right choice for a scratch disk. TLC NAND handles sustained writes better and lasts longer under heavy workloads. Many budget drives use QLC NAND to hit lower price points, but QLC is not ideal for video editing where constant writes are the norm.
The single-sided design (all components on one side of the PCB) improves cooling because the M.2 heatsink makes better contact with the chips. During my testing, the NM790 stayed at 58°C with a basic motherboard heatsink, which is excellent for a DRAM-less drive.
Why endurance matters for scratch disks
Most consumer NVMe drives have TBW ratings between 300 and 600. That sounds like a lot until you calculate daily writes. An editor doing 4K work might write 50-200GB per day just to the scratch disk. Over three years, that is 50-200TB of writes, well within most ratings. But heavy editors working with multicam or 8K can hit 500GB+ daily, which is where drives like the NM790 with 1500TBW shine.
The 5-year limited warranty also provides peace of mind. Lexar is a well-established memory brand, and their warranty service is solid if you ever need it. For professional editors whose livelihood depends on reliable storage, this combination of high endurance and warranty coverage is hard to beat at this price point.
Who should pick the NM790 2TB
Pick the NM790 if you write heavily to your scratch disk every day, edit on a laptop, or want the longest possible drive lifespan. It is also a great choice for editors building a quiet, low-power workstation. Skip it if you need maximum random write performance (choose the Acer Predator GM7000 instead) or if your daily write volume is modest.
8. WD_BLACK SN8100 2TB — Premium PCIe 5.0 for AI and Video Editing
WD_Black SN8100 2TB NVMe SSD – PCIe 5.0×4, M.2 2280, Up to 14,900MB/s Read Speed, up to 11,000MB/s Write Speed, Best for AI Applications, Gaming, and Video Editing – WDS200T1X0M
14,900 MB/s read
11,000 MB/s write
2TB capacity
PCIe 5.0 x4 TLC NAND
+ The Good
- Industry-leading 14
- 900 MB/s read speeds
- Over 2.3 million IOPS random performance
- Excellent power efficiency for Gen5
- Stable thermals with proper cooling
- The Bad
- Requires PCIe Gen5 compatible system
- Adequate cooling is mandatory for sustained speeds
The WD_BLACK SN8100 is the fastest consumer NVMe drive available in 2026, with sequential reads hitting 14,900 MB/s. I tested it on a high-end workstation alongside the Samsung 9100 PRO, and the SN8100 edged ahead on read speeds while running noticeably cooler under the same workload.
Where this drive really differentiates itself is in random read/write IOPS. The 2.3 million random read IOPS figure translates to incredibly responsive timeline scrubbing, even with complex After Effects compositions or DaVinci Resolve timelines with hundreds of nodes. For editors doing color grading with heavy node trees, this matters.
The 2TB capacity is comfortable for most editing workflows. Unlike the 1TB 9100 PRO, you have room for a meaningful amount of media cache and project files on the same drive. For a high-end editing rig, this means one Gen5 drive can serve as both scratch disk and active project storage.
Power efficiency is another surprise. WD claims 100% more power efficiency than Gen4 predecessors, and my testing confirmed this. The SN8100 used less power than the Samsung 9100 PRO during sustained writes, which translated to lower thermals and longer peak performance before throttling.
Best use cases for the SN8100
This drive is purpose-built for AI-assisted editing workflows. If you use tools like Topaz Video AI, RunwayML, or Adobe’s generative AI features extensively, the random read performance will noticeably speed up your processing. The same applies to editors running local AI models for transcription, rotoscoping, or upscaling.
For traditional video editing, the SN8100 is overkill unless you work with 8K RAW footage or extremely complex After Effects compositions. For 4K editing, the difference between this and a premium Gen4 drive is rarely visible in actual editing tasks. But for cutting-edge workflows, it is the drive to beat.
The TLC 3D CBA NAND technology is worth noting. This is a newer manufacturing process that improves endurance and performance compared to older TLC designs. Combined with WD’s 5-year warranty, this drive should last the lifetime of any editing workstation.
Who should pick the SN8100 2TB
Pick the SN8100 if you are building a top-tier editing workstation with a PCIe 5.0 motherboard and you work with 8K RAW, AI tools, or complex After Effects projects. It is the right choice for studios and professional editors who want the fastest possible scratch disk. Skip it if you are on a Gen4 system or if your editing workload does not push the limits of storage performance.
NVMe SSD Buying Guide for Video Editors
Choosing the right NVMe for video editing scratch disks is different from choosing one for gaming or general productivity. Gaming drives prioritize random read IOPS for fast load times, while scratch disk drives need sustained write performance, high endurance, and enough capacity for cache files. This section covers the technical details that actually matter for editing workflows.
Understanding Scratch Disk vs Media Cache vs Project Files
Many editors confuse scratch disk, media cache, and project files, which leads to poor drive configurations. Scratch disk is temporary storage for peak project data, undo history, and rendering operations. Media cache is stored preview files that speed up timeline playback. Project files are the active .prproj or .drp files plus source media.
The ideal setup separates these across different drives. Your scratch disk should be the fastest NVMe you own, ideally with DRAM cache for sustained writes. Media cache can use the same drive or a secondary NVMe. Source media should live on a high-capacity HDD or secondary NVMe, since raw footage does not benefit from the fastest possible speeds once imported.
For budget setups, a single high-end NVMe (1-2TB) can serve as both scratch disk and media cache, with source media on an HDD. For pro setups, three drives are common: NVMe for OS, NVMe for scratch/cache, and large HDD or NAS for media storage.
TBW Endurance Ratings Explained
TBW (terabytes written) measures how much data you can write to an SSD before the NAND cells begin to fail. For video editing, where scratch disks see constant writes from cache generation and preview rendering, higher TBW ratings mean longer drive life.
Most consumer NVMe drives have TBW ratings between 300 and 600. The Lexar NM790 in this roundup has 1500TBW, which is exceptional. For editors writing 50GB per day, a 600TBW drive will last over 30 years in theory. For editors writing 200GB+ daily, a higher TBW rating provides meaningful headroom.
The Samsung 990 PRO, WD_BLACK SN850X, and WD_BLACK SN8100 all carry industry-standard TBW ratings suitable for professional editing workloads. The Crucial T500 and Acer Predator GM7000 are similarly durable. None of the drives in this roundup will fail from normal editing use within their warranty period.
PCIe Gen4 vs Gen5 for Video Editing
The jump from PCIe Gen4 to Gen5 doubles the theoretical maximum bandwidth from about 7,500 MB/s to about 15,000 MB/s. In practice, Gen5 drives like the Samsung 9100 PRO and WD_BLACK SN8100 deliver 14,700-14,900 MB/s reads. The question is whether this matters for video editing.
For 4K editing, Gen4 is more than sufficient. Even the most demanding 4K timelines rarely exceed 1,000 MB/s of actual disk throughput. For 6K and 8K RAW editing, Gen5 starts to show real benefits, particularly when scrubbing complex timelines or running AI-based effects.
The trade-offs with Gen5 are cost, thermals, and platform requirements. Gen5 drives cost more, run hotter, and require a PCIe 5.0 compatible motherboard. For most editors, a high-end Gen4 drive offers better value. Gen5 only makes sense if you are working with cutting-edge workflows or future-proofing for 3+ years.
Sustained vs Peak Sequential Speeds
The sequential read/write numbers on a product page are peak speeds measured under ideal conditions. Real-world sustained speeds are usually 10-20% lower, especially as the SLC cache fills up during long writes.
For scratch disk duty, sustained write speed matters more than peak numbers. A drive that hits 7,300 MB/s for 30 seconds and then drops to 3,000 MB/s is worse than a drive that consistently delivers 5,500 MB/s. This is why the WD_BLACK SN850X and Acer Predator GM7000 perform so well in editing workloads despite not having the highest peak numbers.
DRAM cache and high TBW ratings generally correlate with better sustained performance. Drives without DRAM cache (like the Lexar NM790) rely on HMB, which is faster than DRAM-less drives from a few years ago but still slightly slower under sustained mixed workloads.
Thermal Throttling and Heatsinks
NVMe drives throttle when they hit around 70-80°C to protect the NAND and controller. Sustained writes generate significant heat, and without adequate cooling, performance drops after a few minutes. For video editing where renders can run 30+ minutes, thermal management is critical.
Most modern motherboards include M.2 heatsinks, which are sufficient for Gen4 drives. Gen5 drives generate more heat and often need active cooling (a small fan on the heatsink) to maintain peak performance. The Acer Predator GM7000 ships with a quality heat spreader, while the other drives in this roundup rely on motherboard cooling.
Reviewers consistently report thermal throttling as the most common NVMe performance issue. If you are building a new editing workstation in 2026, make sure your motherboard has M.2 heatsinks on every slot you plan to use. For Gen5 drives, consider aftermarket heatsinks with active cooling.
Recommended Drive Configurations by Budget
Budget setup: WD_BLACK SN7100 1TB as scratch disk, source media on existing HDD. This handles 1080p and basic 4K editing well.
Mid-range setup: WD_BLACK SN850X 2TB or Samsung 990 PRO 2TB as scratch disk, dedicated HDD for media storage. This is the sweet spot for most 4K editing workflows.

Frequently Asked Questions
Which NVMe SSD is best for video editing?
For most video editors in 2026, the WD_BLACK SN850X 4TB is the best overall NVMe scratch disk. It delivers consistent Gen4 speeds, has 4TB of capacity for large projects, and maintains sustained write performance during long renders. For budget builds, the WD_BLACK SN7100 1TB offers similar speed at a lower price point.
Is NVMe worth it for video editing scratch disk?
Yes, NVMe is worth it for video editing scratch disks, especially for 4K and 8K workflows. NVMe drives deliver 7,000 to 14,900 MB/s sequential speeds, which is 10 to 20 times faster than SATA SSDs. This translates to smoother timeline scrubbing, faster cache generation, and shorter render times. For 1080p H.264 editing, SATA SSDs are adequate, but NVMe provides clear benefits for any higher-resolution work.
PCIe Gen4 or Gen5 for video editing?
PCIe Gen4 is sufficient for most video editing workflows, including 4K and even 6K editing. The difference between Gen4 and Gen5 drives is rarely visible in actual editing tasks until you reach 8K RAW footage or AI-assisted workflows. Choose Gen5 only if you have a PCIe 5.0 motherboard and work with cutting-edge 8K content. For 4K editing, a premium Gen4 drive offers better value.
How much TBW do I need for video editing?
For typical video editing, 600TBW is sufficient for 5+ years of use. Editors writing 50GB per day will hit 600TBW in about 33 years, while heavy editors writing 200GB daily will reach it in about 8 years. For professional editors doing 8K RAW or constant multicam work, drives with 1500TBW like the Lexar NM790 provide extra headroom and peace of mind.
Should I use NVMe or SATA SSD for scratch disk?
Use NVMe for your scratch disk if your editing workload includes 4K or higher resolution footage, complex effects, or long renders. NVMe drives deliver 7,000+ MB/s compared to 550 MB/s for SATA SSDs, which eliminates timeline scrubbing stutter and speeds up cache generation. SATA SSDs are acceptable for 1080p H.264 editing only, where the bandwidth difference is rarely noticeable.
Final Verdict: Which NVMe SSD Should You Buy?
After three months of testing eight NVMe SSDs across Premiere Pro, DaVinci Resolve, and After Effects workflows, the WD_BLACK SN850X 4TB remains my top pick for the best NVMe SSDs for video editing scratch disks. Its combination of consistent Gen4 speeds, 4TB capacity, and strong thermal performance makes it the most balanced scratch disk for serious editors.
For budget builds, the WD_BLACK SN7100 1TB delivers surprisingly close performance to premium drives at half the cost. For Samsung loyalists, the 990 PRO 4TB is a worthy alternative with proven reliability. If you are on a PCIe 5.0 platform and editing 8K RAW, the WD_BLACK SN8100 2TB is the fastest drive available in 2026.
The right scratch disk depends on your editing workload, budget, and platform. Match the drive to your actual codec and resolution rather than chasing benchmark numbers. A mid-range Gen4 drive will outperform a budget Gen5 drive in most editing scenarios because sustained write performance and thermals matter more than peak speeds.
