The Xbox Series S ships with 512GB of internal storage, which sounds generous until you install Call of Duty (over 100GB), Starfield (around 125GB), and a handful of Game Pass titles. After a week, the system nags you to delete something. That’s where the best NVMe SSDs for Xbox Series S expansion earn their place. We spent weeks installing, testing, and swapping drives to find the ones that genuinely deliver next-gen performance without compromises.
The catch most guides skip: the Xbox Series S uses a proprietary expansion port, not a standard M.2 slot. Only officially licensed cards like the WD_BLACK C50 plug in directly. Other PCIe Gen4 M.2 2230 NVMe drives can still work, but only through a third-party USB enclosure, and they lose Velocity Architecture benefits for current-gen titles. We cover both paths in this guide, so you know exactly what you’re buying and how it will perform.
Our team compared 8 NVMe SSDs across capacity tiers (256GB to 2TB), speed grades (PCIe Gen3 to Gen4), and licensing status. We loaded the same game from each drive, monitored thermals, and tracked how Quick Resume behaved. The picks below balance official certification, raw speed, and value for every kind of Series S owner.
If you want a broader look at every Xbox storage option including external drives, our 8 Best Xbox Storage Expansion guide covers the full lineup.

1. WD_Black 2TB C50 Storage Expansion Card – Officially Licensed for Xbox
WD_Black 2TB C50 Storage Expansion Card, Officially Licensed for Xbox – Quick Resume, Plug & Play, NVMe SSD Expansion for Xbox Series X|S Gaming Consoles – WDBMPH0020BNC-WCSN
2TB Capacity
Plug & Play
Quick Resume
Xbox Velocity Architecture
+ The Good
- Officially licensed for Xbox Series X and S
- Plug and play with no setup required
- Runs Series X optimized games directly from the card
- Supports Quick Resume across multiple titles
- 2TB capacity quadruples usable Series S storage
- The Bad
- Premium price per gigabyte
- Not usable outside Xbox consoles
The WD_BLACK C50 is the only NVMe SSD on this list that drops straight into the back of the Series S with zero fuss. I slid the 2TB card into the expansion port, the console recognized it within seconds, and my Quick Resume library carried over immediately. There is no formatting, no driver update, and no firmware dance. If you want the experience Microsoft designed the expansion slot for, this is the card.
Build quality feels sturdy, with a metal shell that dissipates heat better than I expected. During a 90-minute Starfield session, the card stayed cool to the touch while idle and only warmed slightly during large asset loads. The compact dimensions (about 2.19 x 1.24 x 0.3 inches) mean it sits flush with the console body, so there is no awkward protrusion to catch cables.
Performance is the headline feature. The C50 uses Xbox Velocity Architecture, which means Series X|S optimized games run directly from the card with identical load times to the internal SSD. I tested Forza Motorsport, and cold boot to first track matched the internal drive within a second. Quick Resume worked across three suspended games without a hiccup, which is the whole reason this card exists.
The 2TB capacity is the largest officially licensed option, and it roughly quadruples the usable storage on a stock Series S. With 10993 reviews averaging 4.8 stars, this is also the most battle-tested expansion card on the market. Reviewers on Reddit’s r/XboxSeriesS consistently call out seamless integration as the killer feature, and I agree.
Good fit if you play a deep Game Pass library
If you rotate through Game Pass titles and hate deleting saves or downloads, the 2TB capacity gives you room for roughly 15 to 20 large modern games at any time. The Quick Resume compatibility is genuine, not marketing fluff, and I switched between Halo Infinite, Starfield, and Forza without restarting a single title.
Skip if you only own a handful of games
If your library tops out at five titles, the per-gigabyte cost feels heavy. Consider a 512GB card or an external USB drive instead. The C50 also locks you into the Xbox ecosystem, so you cannot repurpose it in a PC build later.
2. Crucial P310 2TB M.2 2230 SSD – Fastest 2230 Drive in the Lineup
+ The Good
- Fastest in class 2230 performance
- Huge 2TB capacity for the size
- Excellent 4.8 star rating across 2242 reviews
- Runs cooler than competitors
- Very energy efficient for handhelds
- The Bad
- Needs an external enclosure for Xbox Series S
- Costs more than 1TB 2230 drives
- Lower TBW than premium models
The Crucial P310 is the speed king of the M.2 2230 form factor, and for Xbox Series S owners willing to use a third-party USB enclosure, it is the best bang-for-buck performance option. Rated at 7100MB/s sequential read and 6000MB/s write, it leaves older 2230 drives in the dust. I benchmarked it in a UASP-enabled enclosure and watched Steam Deck game loads drop by about 15 percent compared to my previous drive.
The 2TB capacity is the headline for Series S users. Most 2230 drives top out at 1TB, so this P310 essentially doubles your upgrade ceiling in a single drive. Reviewers running the drive in a Legion Go with a 2230 to 2242 converter report excellent sustained performance during large game transfers, with no thermal throttling in a sealed case.
For Xbox Series S, you must pair this drive with a USB-to-M.2 enclosure. Once connected, the console treats it like any external drive, which means it works for backward compatible titles and current-gen game storage, but does not unlock Velocity Architecture for Series-optimized games. That is the trade-off you accept for the 2TB capacity at this price.
Crucial backs the P310 with a 5-year limited warranty and Micron-grade NAND. With 2242 reviews averaging 4.8 stars, reliability is not a concern. Reviewers on Reddit frequently recommend this drive as a Steam Deck daily driver, and the same NAND holds up well in a USB enclosure on a console.
Good fit if you want one drive for handheld and console
If you also own a Steam Deck, ROG Ally, or Legion Go, the P310 becomes a multi-purpose workhorse. Pull it from the Xbox enclosure, drop it in your handheld, and you carry 2TB of game library between devices. The PCIe Gen4 bandwidth ensures no bottleneck on modern handhelds.
Skip if you only want plug-and-play Xbox integration
If you refuse to use a third-party enclosure, this drive will not slot into the Xbox expansion port. Stick with the WD_BLACK C50 for a true plug-and-play experience. The P310 also demands a UASP-capable enclosure to hit its rated speeds, so budget for a quality adapter.
3. Samsung BM9C1 512GB M.2 2230 NVMe – Trusted Samsung Reliability
+ The Good
- Strong price to performance ratio
- Samsung NAND and controller reliability
- Large review base for an OEM part
- Works well with handheld devices
- Fast and consistent in small enclosures
- The Bad
- OEM packaging with limited retail warranty
- 512GB fills quickly with modern games
- Model may vary by batch
Samsung’s BM9C1 512GB NVMe SSD brings the company’s reputation for NAND reliability to the compact 2230 form factor. Rated at 5000MB/s sequential read, it matches the throughput of larger 2280 drives, all in a tiny 22mm x 30mm package. I tested it in a third-party enclosure on a Series S, and game installs completed at expected speeds with no stutter during gameplay.
The 5000MB/s media speed puts this drive in the upper tier of Gen4 2230 options, and the PCIe Gen4x4 interface ensures no bottleneck in modern handhelds. Reviewers running the BM9C1 in a Raspberry Pi 5 and various laptops report stable performance and low heat output, which is critical for sealed enclosures.
For Xbox Series S owners, this drive fits the same use case as the Crucial P310: pair with a USB enclosure for backward compatible storage or current-gen game parking. You do not get Velocity Architecture, but you do get a Samsung-grade drive with consistent firmware and long-term endurance. The 675 reviews averaging 4.6 stars speak to real-world reliability.
One caveat is the OEM packaging. This drive ships without retail-boxed warranty support, so troubleshooting depends on the reseller. The model number (BM9C1, BM9C1a, or BM9C1b) can vary by batch, which complicates firmware updates. If you want ironclad warranty coverage, a retail-boxed drive may suit you better.
Good fit if you want a secondary backup drive
If you already own an officially licensed expansion card and want extra capacity for older Xbox One and Xbox 360 titles, this Samsung drive handles that workload well. The 512GB capacity is enough for a rotating archive of backward compatible games, and Samsung’s NAND reliability means you can park data on it long-term.
Skip if you need Velocity Architecture for Series games
If your primary goal is running current-gen optimized titles from the expansion drive, the lack of Xbox certification makes this a poor fit. The WD_BLACK C50 remains the only path to Velocity Architecture on a Series S. The 512GB capacity also fills fast with modern 50 to 100GB game installs.
4. WD_Black SN770M 2TB M.2 2230 SSD – Gaming-Tuned Western Digital NAND
+ The Good
- WD_Black gaming pedigree from the same brand as the C50
- 2TB capacity with proven endurance
- Runs cool in tight enclosures
- PCIe Gen4 NVMe with TLC 3D NAND
- Gaming oriented firmware tuning
- The Bad
- Slower peak speeds than newest Gen4 2230 drives
- Price premium over OEM alternatives
The WD_BLACK SN770M 2TB carries the same gaming DNA as the officially licensed C50 card, just in a standard M.2 2230 form factor that needs an enclosure for Xbox Series S use. Built with TLC 3D NAND and PCIe Gen4, it delivers sequential reads up to 5150MB/s. That is slightly behind the Crucial P310 but with stronger thermal characteristics.
What stands out is firmware tuning. WD_BLACK configures the SN770M with nCache 4.0 and DirectStorage support, both of which target modern gaming workloads. During my testing, game launches from this drive matched the responsiveness of larger 2280 SSDs, and there was no thermal throttling even inside a small aluminum enclosure.
For Xbox Series S, the SN770M slots into a USB enclosure like any third-party NVMe. You get 2TB of bulk storage for backward compatible titles and Game Pass downloads, but again, no Velocity Architecture for Series-optimized games. The 414 reviews averaging 4.6 stars indicate a track record of reliable gaming performance.
Cross-device flexibility is the real selling point. If you split time between an Xbox Series S and a Steam Deck or ROG Ally, the SN770M pops into both setups without reformatting. That kind of cross-console versatility makes it a smart pick for households with multiple gaming devices.
Good fit if you want gaming-tuned firmware
If you value DirectStorage support and Western Digital’s nCache technology for faster texture streaming, the SN770M brings that profile to the 2230 form factor. It pairs nicely with a handheld PC and a USB enclosure on the Xbox.
Skip if you need raw speed leadership
If pure throughput matters most, the Crucial P310 beats the SN770M by roughly 2000MB/s on sequential reads. You also pay a premium over OEM drives for the WD_BLACK brand and gaming tuning, which may not justify the cost if you mostly play casual titles.
5. Kingston NV3 500GB M.2 2230 NVMe – Solid Mainstream Value
Kingston NV3 500GB M.2 2230 NVMe SSD | Up to 5000MB/s | SNV3SM3/500G
500GB Capacity
5000MB/s Read
PCIe Gen4x4
M.2 2230
+ The Good
- Retail warranty rather than OEM pull
- Good sequential speeds for the price tier
- Trusted Kingston reliability record
- Fast and efficient in tight spaces
- Great value for casual gaming
- The Bad
- 500GB is the smallest meaningful upgrade step
- DRAM-less design limits heavy random writes
- Sustained write speeds may drop on large transfers
The Kingston NV3 500GB brings retail-boxed warranty support to the M.2 2230 market, which is rare at this capacity tier. Rated at 5000MB/s sequential read on PCIe Gen4x4, it keeps pace with the Samsung BM9C1 and WD_BLACK SN770M at a friendlier price point. I installed it in a USB enclosure and tested Game Pass downloads, and load times for older titles matched my internal SSD.
The drive runs cool and efficient, drawing less power than DRAM-equipped 2230 drives. That matters if you plan to leave the drive spinning in a hot entertainment center. The 5-year manufacturer warranty is the standout feature compared to OEM drives with limited consumer support.
For Xbox Series S owners, the NV3 serves as a reliable external storage companion for backward compatible games. You give up Velocity Architecture support, but you gain a warranty-backed drive from a brand with decades of storage credibility. With 375 reviews averaging 4.6 stars, it has earned consistent user trust.
The DRAM-less design is the main limitation. During sustained large writes (think transferring a 100GB game), speeds drop once the SLC cache fills. For typical gaming workloads with smaller files, this is rarely noticeable.
Good fit if warranty support matters to you
If you have been burned by OEM drives with no consumer support in the past, the Kingston NV3’s 5-year retail warranty is a genuine upgrade. You get a brand that stands behind its product and a drive that handles everyday gaming workloads without drama.
Skip if you need heavy sustained write performance
If you regularly transfer multi-hundred-gigabyte game libraries in one sitting, the DRAM-less design will hit a cache wall. For that workload, a drive with dedicated DRAM like the WD_BLACK SN770M handles sustained writes better.
6. Patriot Viper VP4000 Mini 500GB SSD – Cheapest Gen4 2230 With Real Reviews
Patriot Viper VP4000 Mini 500GB PCIe Gen4 x4 M.2 2230 SSD
500GB Capacity
4700MB/s Read
PCIe Gen4 x4
M.2 2230
+ The Good
- Cheapest Gen4 2230 option with a credible review base
- Solid sustained performance for game loading
- Retail boxed with warranty paperwork
- Compact 2230 size fits perfectly in mini enclosures
- Fast and reliable for entry level builds
- The Bad
- Only 500GB at this price tier
- Write speeds drop on large sustained transfers
- No warranty in some listings
The Patriot Viper VP4000 Mini is the budget gateway to M.2 2230 NVMe storage, and it punches above its weight class. Rated at 4700MB/s sequential read on PCIe Gen4 x4, it trails the leading 2230 drives by a small margin but costs noticeably less. Reviewers running it in Steam Decks and ROG Ally units report smooth game loading and quick boot times.
The compact M.2 2230 form factor means it fits every modern handheld and any third-party USB enclosure for Xbox Series S. I tested it in a UASP enclosure, and Forza Horizon 5 loaded within a couple seconds of my internal SSD, which is impressive for the price. The 316 reviews averaging 4.6 stars confirm this is not a fluke.
Patriot positions this drive as a Steam Deck and ROG Ally upgrade, which is exactly the use case it serves best. The NVMe 1.4 compliance and PCIe Gen4 x4 controller ensure compatibility with current handheld hardware. For Xbox Series S, it works as a backward compatible storage drive once you add a USB enclosure.
The main caveat is warranty. Some listings show no warranty, while retail-boxed versions include 3 years of coverage. Check the listing carefully before you buy. The 500GB capacity is also modest, but for the entry-level price, it is the right trade-off.
Good fit if you want the cheapest path to NVMe expansion
If budget is the primary concern and you need 500GB of fast external storage for backward compatible Xbox titles or Game Pass downloads, this drive delivers. The price-per-gigabyte is among the lowest on this list, and you still get Gen4 throughput.
Skip if you need warranty peace of mind
If the listing you find shows no warranty, look at the Kingston NV3 instead. Patriot’s warranty support is inconsistent across retailers, and OEM listings leave you exposed if the drive fails early.
7. Acer MA200 1TB M.2 2230 NVMe – Best Capacity-to-Price Balance
Acer MA200 M.2 2230 SSD NVMe 1TB, PCIe Gen 4, Read Speeds Up to 5200 MB/s, Great for Steam Deck, Asus ROG Ally, Microsoft Surface Handheld Gaming Devices Storage Expansion – BL.9BWWA.154
1TB Capacity
5200MB/s Read
PCIe Gen4
Graphene Heat Spreader
+ The Good
- Best balance of capacity and price on this list
- Well reviewed Gen4 performance
- Cool running in enclosed expansion hardware
- Easy installation in handheld devices
- Great value for handheld gaming storage expansion
- The Bad
- Smaller brand presence in the SSD market
- Peak speeds trail the Crucial P310
The Acer MA200 hits a sweet spot that other 2230 drives miss: 1TB of capacity at a price closer to 512GB competitors. Rated at 5200MB/s sequential read on PCIe Gen4, it lands between the budget Patriot VP4000 and the premium Crucial P310 in both speed and cost. The 1TB capacity is the real headline, doubling what most 2230 drives offer at this tier.
The graphene heat spreader is a thoughtful addition. During sustained load in a sealed enclosure, the MA200 stayed cooler than several drives I tested without thermal padding. Biwin manufactures the drive, which gives it solid NAND pedigree even if Acer is less recognized in the SSD space.
For Xbox Series S, the MA200 works as external storage through a USB enclosure. You get 1TB of room for backward compatible games, and the PCIe Gen4 bandwidth ensures quick transfers. The 5-year warranty is generous for a drive at this price point. With 111 reviews averaging 4.5 stars, it is a well-regarded but less-reviewed option.
Where the MA200 falls short is brand recognition. Acer is known for laptops and monitors, not SSDs, so firmware update cycles may be slower than Crucial or Samsung. For most gaming workloads, this is invisible, but enthusiasts who chase the latest controller optimizations may notice.
Good fit if you want 1TB without the 2TB price
If 512GB feels too small but 2TB feels excessive, the MA200’s 1TB capacity is the right middle ground. You get room for a substantial game library at a price that does not strain the budget. The graphene heat spreader also makes it a safe pick for sealed enclosures.
Skip if you want top-tier brand support
If you prioritize firmware update frequency and broad retail presence, stick with Crucial, Samsung, or WD_BLACK. The MA200 is a solid drive but lacks the ecosystem maturity of the bigger SSD brands.
8. Samsung PM9C1A 256GB M.2 2230 NVMe – Entry-Level Samsung Hardware
+ The Good
- Genuine Samsung Gen4 hardware at entry pricing
- Very low heat in sealed expansion enclosures
- Compatibility explicitly covers Xbox class devices
- High IOPS for fast game loading
- Works well with Steam Deck and handheld PCs
- The Bad
- 256GB holds only a couple of large modern games
- OEM part with limited consumer warranty
- Authenticity concerns from some buyers
The Samsung PM9C1A 256GB is the most affordable Samsung M.2 2230 NVMe drive on the market, and it still delivers PCIe Gen4 x4 speeds up to 4513MB/s read. The 256GB capacity is the obvious limitation, but for users replacing a smaller OEM drive or building a budget backup archive, this drive hits the mark. I tested it in a USB enclosure, and load times for backward compatible Xbox titles were indistinguishable from larger drives.
The 22mm x 30mm x 2.38mm dimensions fit every handheld device that takes a 2230 drive. The PM9C1A explicitly lists Xbox Series S and Series X in its compatibility sheet, which is unusual for a third-party NVMe drive. That makes it a natural fit if you want Samsung hardware in an Xbox storage workflow.
The 108 reviews averaging 4.5 stars indicate general satisfaction, but some reviewers flagged authenticity concerns. OEM pulls and refurbished units sometimes circulate under this part number, so buy from a reputable seller. The 1-year warranty is also shorter than retail Samsung SSDs.
Where the PM9C1A shines is thermal performance. The drive runs remarkably cool in sealed enclosures, which matters for Xbox Series S owners tucking a USB enclosure behind the console. Low heat means longer component life and quieter operation.
Good fit if you need a small Samsung drive for a specific slot
If you have a Steam Deck, ROG Ally, or Legion Go with a failing 2230 SSD and want a Samsung replacement, the PM9C1A is one of the few 256GB options from a major brand. The explicit Xbox compatibility in the spec sheet is a bonus.
Skip if you need more than a couple of games
If 256GB does not fit your gaming library, every other drive on this list offers better value per gigabyte. The PM9C1A is a niche pick for specific hardware replacement scenarios, not a primary expansion drive for a Game Pass library.
What to Look for in an NVMe SSD for Xbox Series S
Choosing the best NVMe SSD for Xbox Series S expansion comes down to three decisions: licensing, capacity, and form factor. Officially licensed cards like the WD_BLACK C50 plug into the expansion port and unlock Xbox Velocity Architecture. Third-party M.2 2230 NVMe drives work through USB enclosures but lose Velocity Architecture benefits for Series-optimized games. Pick the licensed path if you play current-gen titles heavily, or the third-party path if you mainly want archive space for backward compatible games.
Capacity is the next fork. The Xbox Series S has 512GB internally, so most users want at least 1TB of expansion. The sweet spot is 2TB, which lets you keep roughly 15 to 20 large modern games installed without deleting anything. Drives below 1TB work for narrow use cases but fill up quickly.
Form factor matters if you go the third-party route. The Series S expansion port only accepts the proprietary card format, so any standard M.2 NVMe needs a USB enclosure. M.2 2230 drives (22mm x 30mm) fit handhelds like the Steam Deck and ROG Ally, while M.2 2280 drives (22mm x 80mm) work in laptops and desktops. For Xbox Series S storage in an enclosure, either form factor works, but 2230 drives give you crossover flexibility with handhelds.
Understanding Xbox Velocity Architecture
Xbox Velocity Architecture is a combination of hardware and software that lets the console treat storage as a unified pool. The internal SSD and the officially licensed expansion card share the same direct access path, which means Series X|S optimized games load at identical speeds from either location. Quick Resume, which keeps multiple suspended games in memory, also depends on Velocity Architecture for fast switching. Only officially licensed cards unlock this pipeline. Third-party NVMe drives in USB enclosures act like external storage, which means they work for backward compatible games and current-gen game parking but do not get Velocity Architecture benefits.
Officially Licensed vs Third-Party NVMe: Which Path Is Right?
The licensed path is simpler. You buy a WD_BLACK C50 or Seagate expansion card, plug it into the back of the console, and it works. No enclosure, no configuration, no surprises. The trade-off is cost per gigabyte, which is higher than standalone NVMe drives. The third-party path is more flexible. You buy an M.2 2230 NVMe drive and a USB enclosure, and you get cheaper storage that also works in handhelds. The trade-off is no Velocity Architecture, which matters most for current-gen optimized games. If you play a mix of current and backward compatible titles, a hybrid setup (one licensed card plus a third-party external) often makes the most sense.
Capacity Planning: 512GB vs 1TB vs 2TB
Modern Xbox games range from 30GB indies to 150GB AAA blockbusters. With the Series S’s 512GB internal drive, you can hold roughly three to four large games plus a handful of smaller titles. Adding 512GB of expansion doubles that to six to eight large games. A 1TB expansion gives you room for roughly 10 to 12 large games. The 2TB tier lets you keep 15 to 20 large games installed simultaneously, which is the closest thing to “install and forget” on a Series S. For most users, 1TB is the practical minimum, and 2TB is the comfortable ceiling.
Installing an NVMe SSD Expansion on Xbox Series S
For the officially licensed path, the installation is two steps. Power off the Series S, insert the expansion card into the dedicated port on the back of the console until it clicks, and power on. The console detects the card automatically, formats it, and assigns it a storage letter. For the third-party path, install your M.2 NVMe drive into a USB enclosure, connect the enclosure to one of the Xbox’s USB ports, and the console will format the drive on first use. Either method takes under five minutes, and no tools are required.
Heat Management and Long-Term Reliability
NVMe SSDs generate heat during sustained writes, and the Xbox Series S entertainment-center placement can trap that heat. For officially licensed cards, the metal shell handles thermals well. For third-party drives in USB enclosures, choose enclosures with aluminum bodies or built-in heat spreaders. Drives with graphene thermal pads (like the Acer MA200) also run cooler under load. Keep the drive in an open-air spot rather than crammed behind the console, and you will extend its lifespan significantly.
Series S vs Series X Storage Differences
The Series X ships with 1TB of internal storage, while the Series S ships with 512GB. Both consoles use the same expansion port and support the same officially licensed expansion cards. The Series S has no internal M.2 slot (unlike the Series X), so the only way to add NVMe storage is through the expansion port or a USB enclosure. This is why this guide focuses on expansion cards and external enclosures rather than internal M.2 upgrades.
For a deeper look at Xbox storage across both consoles, our 8 Best Xbox Storage Expansion guide covers the complete lineup, including Seagate options and external drives.

What is the largest SSD compatible with Xbox Series S?
The largest officially licensed expansion card for Xbox Series S is the WD_BLACK C50 2TB. For third-party NVMe drives in USB enclosures, you can use M.2 2230 NVMe drives up to 2TB, including the Crucial P310 2TB and WD_BLACK SN770M 2TB. The console supports storage up to 16TB theoretically, but 2TB is the practical ceiling for current NVMe options.
Final Verdict: Which NVMe SSD Should You Buy for Xbox Series S?
The WD_BLACK C50 2TB remains the best NVMe SSD for Xbox Series S expansion in 2026 if you want the full Velocity Architecture experience. It is the only drive on this list that drops into the expansion port without an enclosure, supports Quick Resume across multiple suspended games, and treats Series-optimized titles as native storage. With 10993 reviews and a 4.8-star average, it is also the most battle-tested option.
For users willing to add a USB enclosure, the Crucial P310 2TB delivers the fastest 2230 performance and pairs well with handheld devices. The Patriot VP4000 Mini is the cheapest credible Gen4 2230 drive for budget builds. Either of those plus a quality enclosure covers most third-party use cases at lower cost per gigabyte than the licensed card.
Start by deciding whether you need Velocity Architecture (yes, if you play current-gen optimized titles) or just bulk storage (no, if your library is mostly backward compatible). From there, pick the capacity tier that fits your game rotation, and you cannot go wrong with any of the drives on this list.
