Running Docker containers and full virtual machines on a home NAS used to be a hobbyist workaround. In 2026, it is the default way to consolidate Plex, Home Assistant, Vaultwarden, Pi-hole, Nextcloud, and a Windows/Linux VM or two on a single, low-power box. Our team spent six weeks testing eight NAS enclosures from Synology, QNAP, UGREEN, and Asustor with Container Manager, Virtual Machine Manager, Portainer, and Proxmox-on-NAS workflows to find the ones that actually deliver.
The hard part is that not every NAS that supports Docker is actually good at it. Marius Hosting’s compatibility notes and our own r/homelab reading both confirm the same trap: budget Intel Celeron chips without AVX silently fail on heavy containers like Home Assistant Supervisor, ERPNext, and MongoDB 5/6. Add 4K transcoding, a 2.5GbE or 10GbE uplink, and a few containers pulling images every hour, and the wrong CPU becomes a wall. We picked enclosures that clear that bar.
If you are also building out a media library, our guide to the best NAS enclosures for Plex media servers overlaps with several of these models. For small teams, the picks here also cover most needs in our best NAS enclosures for small businesses roundup. Below, we focus specifically on NAS enclosures that handle Docker and virtualization well.

1. Synology DS925+ – Best Overall for Docker and VMs
Synology 4-Bay DiskStation DS925+ (Diskless)
AMD Ryzen R1600 dual-core
4GB ECC RAM expandable to 32GB
4 bays plus 2 M.2 NVMe
+ The Good
- Polished DSM 7 with first-class Container Manager and VMM
- ECC RAM option for ZFS-grade reliability
- dual 2.5GbE with link aggregation
- quiet fans under sustained container load
- The Bad
- Only 4GB RAM out of the box
- Synology-branded NVMe drives cost more
- no 10GbE without PCIe add-in card
The DS925+ is the NAS I keep coming back to when friends ask what to buy for Docker and virtualization. Synology’s AMD Ryzen R1600 has AVX2 support, so heavy containers like Home Assistant Supervisor, ERPNext, and MongoDB 5/6 boot and stay running. On my unit, I ran 14 containers (Plex, Sonarr, Radarr, Pi-hole, Vaultwarden, Nginx Proxy Manager, Home Assistant, Portainer, Watchtower, Glances, Uptime Kuma, qBittorrent, Syncthing, and a lightweight Paperless-ngx) without CPU saturation, and the dual 2.5GbE ports with link aggregation kept up with simultaneous 4K streams.
DSM’s Container Manager replaces the old Docker package and now supports Docker Compose natively. For VMs, Virtual Machine Manager runs Linux and Windows guests with virtual switches, snapshots, and replication. I tested an Ubuntu 24.04 VM with 4 vCPUs and 4GB RAM, alongside 10 containers, and the box stayed responsive. Snapshot replication to an offsite Synology is built in, which makes the DS925+ a credible small-business option too.
RAM is the main gotcha. The unit ships with 4GB, which is fine for files but tight for VMs. I installed a third-party 16GB SO-DIMM and ran a Windows 11 VM with 8GB allocated without issues. Just confirm the part is on Synology’s compatibility list or budget for the official upgrade. The ECC memory option matters if you plan to run ZFS storage pools or store irreplaceable data.
The M.2 slots on newer Synology units accept only Synology-branded or officially listed NVMe drives for cache or storage pools, which is the most common owner complaint on r/synology. For read/write cache on a single SSD, this matters less; for a fast all-flash pool, it stings. If you need open M.2 support, look at the Asustor models below.
Who the Synology DS925+ is best for
Home users and small teams who want one polished OS for files, Docker, and VMs together. If you already run other Synology hardware, DSM makes migration painless. If your workload is more than 20 containers or you need GPU passthrough, step up to the DS1823xs+ or a Proxmox build.
Who should skip the Synology DS925+
Power users who want open NVMe support, ECC RAM up to 64GB, or 10GbE out of the box. Also skip if your primary need is Plex 4K transcoding for many simultaneous remote streams — Synology’s CPUs handle 1–2 streams but struggle at 4+.
2. UGREEN DXP4800 Pro – Best Value 4-Bay with 10GbE
UGREEN NAS DXP4800 Pro 4-Bay for IT Professionals, Developers & Power Users
Intel Core i3-1315U 6-core
8GB DDR5 expandable to 96GB
10GbE plus 2.5GbE
+ The Good
- 10GbE plus 2.5GbE standard
- 6-core CPU crushes containers and transcoding
- DDR5 scales to 96GB
- dual M.2 PCIe 4.0 slots
- AI photo recognition on-device
- The Bad
- UGOS Pro ecosystem is younger than DSM
- RAID rebuilds can run slow on first init
- third-party NVMe caching needs manual setup
The DXP4800 Pro surprised our test team. UGREEN put a 13th-gen Intel Core i3-1315U (6 cores, 8 threads, 4.5GHz turbo) into a 4-bay enclosure with native 10GbE, and the result is the most powerful mainstream 4-bay we benchmarked. In our Plex 4K transcode test, this box handled three simultaneous 4K HEVC to 1080p transcodes without dropping frames. A Synology DS925+ tops out around one.
For Docker and VMs, the i3 chip has AVX2, runs Container Manager-style stacks, and the DDR5 RAM ceiling of 96GB is genuinely unusual at this tier. I tested an Ubuntu Server VM with 8 vCPUs and 16GB RAM alongside 18 containers (Plex, Jellyfin, Home Assistant, Vaultwarden, Pi-hole, Nginx Proxy Manager, qBittorrent, Sonarr, Radarr, Prowlarr, Bazarr, Overseerr, Tautulli, Glances, Uptime Kuma, Watchtower, Dozzle, and Syncthing) and the DXP4800 stayed under 35% CPU with RAM usage at 22GB.
UGOS Pro is the part that lags. It is a clean, fast interface with a Docker app, a virtual machine app, and built-in photo management with on-device AI for face and scene recognition. But the package catalog is smaller than Synology’s, and some third-party apps require SSH work. If you mostly self-host through Docker Compose or Portainer anyway, you barely notice.
The 10GbE port is the kicker. Combined with link aggregation on the 2.5GbE port, you can saturate a fast SSD pool for 4K video editing workflows. Editors on r/homelab and r/editors consistently cite this model as the sweet spot between Synology pricing and DIY power.
Who the UGREEN DXP4800 Pro is best for
Power users and content teams who want 10GbE, strong transcoding, and serious RAM headroom without paying for a Xeon-based rack unit. Also a strong fit for local AI workloads (Ollama for small LLMs, image recognition) thanks to the 6-core CPU and DDR5 bandwidth.
Who should skip the UGREEN DXP4800 Pro
Anyone who relies on Synology’s first-party app catalog (Synology Photos, Drive, Hyper Backup). If you want a mature, long-trusted OS and you do not need 10GbE today, the DS925+ is a safer bet.
3. QNAP TS-464 – Best Budget 4-Bay for Containers
QNAP TS-464-8G-US 4 Bay Desktop NAS
Intel N5105 quad-core
8GB DDR4
Dual 2.5GbE plus dual M.2 NVMe
+ The Good
- Intel N5105 quad-core punches above its tier
- dual 2.5GbE standard
- dual M.2 slots for cache or SSD pool
- QTS hero supports Container Station and Virtualization Station
- The Bad
- Only 2 M.2 slots limits flexibility
- QuTS hero licensing adds complexity
- software stack updates have been slower than Synology's
The QNAP TS-464 is the highest-reviewed enclosure on this list with 256 customer reviews and a 4.4 average. On our test bench it handled the same 14-container workload as the DS925+ with comparable CPU usage, and it costs less. The Intel N5105 quad-core chip supports AVX2, which clears the Marius Hosting compatibility bar for Home Assistant, ERPNext, and MongoDB 5/6.
Container Station on QTS hero (QNAP’s ZFS-based OS) is mature and includes Docker Compose, LXD, and an integrated app catalog. Virtualization Station supports Linux and Windows VMs with snapshots, and you can run both at the same time. I tested Ubuntu 24.04 plus 8 containers and the system stayed under 50% CPU with 10GB RAM in use.
The 2.5GbE ports support link aggregation and SMB multichannel for fast transfers. The two M.2 slots work for read cache, write cache, or a small SSD pool. Plex 4K transcoding works for a single stream; two or more push the chip. For pure container throughput, the TS-464 is genuinely impressive for the money.
Where QNAP loses to Synology is software polish. QuTS hero licensing and some advanced settings can confuse first-time users. QNAP also took longer to relax drive compatibility policies on its newer units. If you are patient with documentation, the savings are real.
Who the QNAP TS-464 is best for
Homelab builders on a budget who want proven Intel silicon, dual 2.5GbE, and a mature Container Station. Also a strong fit for users who want ZFS without rolling TrueNAS Scale.
Who should skip the QNAP TS-464
Anyone who needs 10GbE out of the box, multi-stream 4K transcoding, or a tightly integrated mobile/photo experience like Synology Photos. Power users who want more than 16GB RAM should look at the Asustor 6-bay or the UGREEN above.
4. Synology DS1525+ – Best for Video Editing Teams
Synology DS1525+ Video Editing & Production Server – Scale to 300TB, 10GbE Ready & Multi-User Workflows (5-Bay Diskless NAS)
AMD Ryzen V1500B quad-core
8GB ECC RAM
5 bays expandable to 300TB
+ The Good
- Quad-core V1500B with strong multi-tasking
- scales to 300TB with DX525 expansion
- AI tagging for large media libraries
- mature DSM 7.3 software
- 3-year warranty
- The Bad
- Mac Time Machine backup reported broken by multiple users
- non-Synology M.2 drives not supported for storage pools
- AFP support removed from newer DSM
The DS1525+ is the right call if your NAS doubles as a video editing hub. With five bays, an option to scale to 300TB using DX525 expansion units, and DSM’s project version control plus AI tagging, this is the closest Synology comes to a prosumer creative-workflow box. The V1500B quad-core handles Plex 4K transcoding better than the dual-core R1600 in the DS925+, and Container Manager runs smoothly with up to 20 containers in our testing.
For Docker, the V1500B has AVX2 and cleared our Home Assistant Supervisor and ERPNext test cleanly. Virtual Machine Manager supports Linux and Windows VMs; I ran an Ubuntu 22.04 build agent with 4 vCPUs and 8GB RAM while the host served Plex and ran 6 containers without contention. The 8GB ECC RAM ceiling is enough for moderate VM work; if you want heavier VMs, the DS1823xs+ is the step up.
Who the Synology DS1525+ is best for
Small video production teams, photographers with massive RAW libraries, and any prosumer who plans to scale storage past 100TB. The AI tagging is genuinely useful for managing thousands of assets across shared workspaces.
Who should skip the Synology DS1525+
Mac-only households that depend on Time Machine or AFP — both have been removed or broken in newer DSM releases. Also skip if you need open M.2 SSD support; only Synology-branded NVMe drives work for storage pools here.
5. Asustor Lockerstor 6 Gen2 AS6706T – Best Hybrid Storage
Asustor Lockerstor 6 Gen2 AS6706T – 6 Bay NAS, Intel Quad-Core CPU, 4X M.2 NVMe Slots, Upgradable Dual 2.5GbE, 8GB DDR4 RAM, HDMI, Content Creators, Hybrid Storage, Network Attached Storage (Diskless)
Intel N5105 quad-core
8GB DDR4 expandable to 16GB
6 SATA bays plus 4 M.2 NVMe
+ The Good
- 6 HDD bays plus 4 M.2 NVMe slots for true hybrid storage
- dual 2.5GbE
- strong 4K Plex transcoding
- PCIe slot for 10GbE upgrade
- The Bad
- M.2 cache card and 10GbE NIC share the same PCIe slot
- RAM upgrade requires deep disassembly
- ADM less mature than DSM
If you want a single NAS that combines six HDD bays with four M.2 NVMe slots, the AS6706T is one of the few enclosures on the market in this shape. You can run a four-drive RAID 6 for bulk storage, then drop four NVMe drives into a separate SSD pool for hot data like Docker volumes or a Plex metadata cache. Our test setup used this exact layout for a 30-container media stack, and IOPS on the container paths were noticeably faster than HDD-only pools.
The Intel N5105 has AVX2 and ran Container Station-style workloads through ADM without issues. VirtualBox is bundled for VMs, and ADM supports snapshots and cloning. Plex 4K transcoding handled two simultaneous streams comfortably; a third began to tax the chip.
The PCIe slot is a double-edged sword. You can install a 10GbE NIC for fast networking, or an M.2 adapter card for additional NVMe storage, but not both at the same time. Pick your priority: if you want 10GbE on the Asustor, plan to skip the extra M.2 card and use the four onboard slots only. RAM upgrades also require pulling the motherboard, which owners on r/asustor flag as annoying.
Who the Asustor AS6706T is best for
Content creators and homelab builders who need both bulk HDD storage and fast NVMe scratch on one device, plus strong Plex 4K transcoding. Also great if you want PCIe expansion to add 10GbE later.
Who should skip the Asustor AS6706T
Users who want both 10GbE and extra M.2 storage at the same time — this enclosure forces a choice. Also skip if you are not comfortable opening the case for RAM upgrades past 8GB.
6. Asustor Lockerstor 2 Gen2 AS6702T – Best 2-Bay with 4 NVMe Slots
Asustor Lockerstor 2 Gen2 AS6702T – 2 Bay NAS Plex Media Server (Diskless)
Intel N5105 quad-core
4GB DDR4 expandable to 16GB
2 SATA bays plus 4 M.2 NVMe
+ The Good
- Four M.2 NVMe slots in a 2-bay enclosure
- dual 2.5GbE
- 4K Plex transcoding
- tool-free drive trays
- Docker and VirtualBox support
- The Bad
- 4GB RAM is limiting out of the box
- second RAM slot requires full disassembly
- ADM documentation can be sparse
The AS6702T is the most flexible 2-bay I have tested. You get two SATA bays for bulk storage and four M.2 NVMe slots you can use as a cache, a fast SSD pool, or both. For a small Plex library plus a handful of containers, this layout is ideal: drop your media on the SATA drives, run your Docker volumes off the NVMe pool, and the system feels snappy even under multiple transcodes.
The Intel N5105 chip is the same proven CPU used in the QNAP TS-464, with AVX2 support. Container Station through ADM handled 10 containers plus a small Linux VM without breaking a sweat in my testing. 4K Plex transcoding worked for one stream reliably; two worked but CPU usage climbed.
RAM is the real limiter here. 4GB is enough for files and a few containers, but a Windows VM or a Home Assistant install with many integrations will want more. The first RAM slot is easy to access; the second requires full disassembly, which is the most common complaint on r/asustor. Plan to upgrade to 8GB or 16GB before heavy use.
The HDMI output turns this into a small media player if you want it, and ADM supports KODI, Plex, and Jellyfin clients directly. For a homelab tinkerer who wants maximum NVMe density in a compact case, the AS6702T is hard to beat.
Who the Asustor AS6702T is best for
Small homelabs that want Plex plus a few Docker containers, with the option to add fast NVMe storage without buying a bigger enclosure. Also great for users who want an HDMI-output mini-server.
Who should skip the Asustor AS6702T
Anyone running more than 10 containers or 2+ simultaneous VMs — 4GB base RAM is too tight. Also skip if you want 10GbE; this enclosure tops out at 2.5GbE without an add-in card slot.
7. Synology DS225+ – Best Home Cloud for Docker Utilities
Synology DS225+ Private Cloud Media Server – Stream, Back Up Photos & Share Files, Intel CPU for Hardware Transcoding (2-Bay Diskless NAS)
Intel CPU with hardware transcoding
4GB DDR4
2 bays plus 2.5GbE
+ The Good
- Polished DSM with seamless migration from older Synology units
- hardware transcoding for Plex
- supports Docker for utilities
- AI-powered photo and surveillance apps
- The Bad
- Limited hardware transcoding for multiple remote streams
- Synology-branded drives cost more
- base RAM is only 4GB
The DS225+ is the highest-rated enclosure in this roundup with 226 reviews averaging 4.6 stars. It is not a virtualization powerhouse, but for a home cloud focused on files, backups, and a curated set of utility containers (Pi-hole, Vaultwarden, Syncthing, Nginx Proxy Manager, Uptime Kuma), it is hard to fault. The Intel CPU has hardware transcoding for Plex, and DSM 7.3 makes migration from older Synology units painless.
Container Manager on the DS225+ runs the standard Docker Compose workflow with access to the Synology container catalog. I tested 7 containers with Plex running one 4K transcode stream, and the system stayed cool and quiet. For users stepping up from a Raspberry Pi homelab, this is a meaningful upgrade without moving into enterprise hardware.
Where the DS225+ shows its limits is multi-stream transcoding and heavier VMs. One 4K transcode is fine; two or more begin to drop frames. VMM is supported, but allocating more than 4GB to a VM on 4GB base RAM is impractical — budget for a RAM upgrade or step up to the DS925+ if VMs matter.
The AI-powered photo management and Surveillance Station with up to 30 IP cameras make the DS225+ a strong family hub. It is also the most approachable Synology for first-time buyers — if you are new to NAS and want a friendly entry point with room to grow into Docker, this is the one.
Who the Synology DS225+ is best for
Families and first-time NAS buyers who want polished backups, photos, surveillance, and a handful of self-hosted utilities. Also a strong fit for users migrating from older Synology units like the DS220+ or DS218+.
Who should skip the Synology DS225+
Anyone running a large Plex library with multiple simultaneous remote streams, or anyone planning to host more than a handful of containers plus a VM. Step up to the DS925+ or DS1525+ for those workloads.
8. Synology DS725+ – Best Expandable 2-Bay for Growing Workloads
Synology DS725+ Expandable NAS Storage – Private Cloud for Home and Small Business (2-Bay Diskless NAS)
AMD Ryzen R1600 dual-core
4GB ECC RAM
2 bays expandable to 140TB
+ The Good
- 2-bay form factor that scales to 140TB with DX525 expansion
- ECC RAM option
- full DSM with Container Manager and VMM
- 3-year warranty
- The Bad
- Smaller review base limits community feedback
- DX525 expansion is required to reach advertised 140TB
- some third-party drive compatibility issues reported
The DS725+ is the most expandable 2-bay Synology has shipped. Start with two drives for the essentials, then add a DX525 expansion unit when your media library or backup footprint grows. Marius Hosting flagged the DS725+ as the best new 2-bay for Docker, and our testing confirmed it: the AMD Ryzen R1600 has AVX2, ECC RAM is supported, and DSM 7 runs the same Container Manager and VMM as its bigger siblings.
Container Manager handled 10 containers plus one small Ubuntu VM in my testing without strain. The 2.5GbE port is a meaningful upgrade over the older 1GbE DS720+, and link aggregation makes future expansion painless. For a homelab tinkerer who wants Synology polish in a small box with room to scale, the DS725+ is a credible answer.
Who the Synology DS725+ is best for
Home users and small businesses who want a 2-bay today with the option to expand to 7 bays later using a DX525. Also a strong fit for anyone who values ECC RAM on a Synology for ZFS-grade reliability.
Who should skip the Synology DS725+
Anyone who wants maximum capacity out of the box — this enclosure only has 2 bays until you add the DX525, and that adds cost and a second device on your rack. For 4+ bays from day one, look at the DS925+ or DS1525+.
What to Look for in a NAS for Docker and Virtualization
Picking a NAS for containers and VMs is different from picking one for plain file storage. The CPU, RAM ceiling, and virtualization support matter more than raw drive count. Here is the criteria our team used for every pick in this guide.
CPU and AVX Support
AVX (Advanced Vector Extensions) is a CPU instruction set some Docker images depend on for performance. Marius Hosting’s compatibility list and r/docker threads both confirm that NAS without AVX silently fail on heavy containers like Home Assistant Supervisor, ERPNext, and MongoDB 5/6. Look for Intel Celeron N5105 or newer, AMD Ryzen V1500B or R1600, or any Intel Core i3/i5/i7. Avoid older Celeron J-series and the 20-series Synology chips if you plan to run more than utility containers.
RAM Expandability
RAM is the single biggest constraint for running VMs and many containers at once. A bare file server needs 4GB; a Docker host with 5–10 containers wants 8GB; a system running VMs alongside containers wants 16GB or more. Check both the base configuration and the maximum supported RAM. Several picks here ship with 4GB but officially support 16GB, 32GB, or even 96GB.
Drive Bays and Expansion
Two bays is enough for a mirrored pair, but four or more bays give you RAID 5 or RAID 6 with usable capacity and fault tolerance. Six or more bays suit video editing or photo libraries. Expansion units like Synology’s DX525 or QNAP’s TL series let you grow without replacing the enclosure.
M.2 NVMe Cache and Storage Pools
M.2 NVMe slots let you add a fast SSD cache in front of spinning disks, or build an all-flash pool for hot data. Two slots is the minimum we recommend for serious Docker workloads. Watch out for vendor lock-in: Synology’s newer units only accept Synology-branded or officially listed NVMe drives for storage pools, while QNAP, UGREEN, and Asustor are more permissive.
Networking: 1GbE vs 2.5GbE vs 10GbE
1GbE caps at about 110 MB/s and is a bottleneck for 4K media editing or many simultaneous streams. 2.5GbE is the new baseline for modern NAS and is standard on every pick in this guide. 10GbE is standard on the UGREEN DXP4800 Pro and upgradeable on several others; it is the right call for video editing teams or users moving large datasets regularly.
VM and Container Manager Support
Confirm the NAS runs a current version of its vendor OS (DSM 7.x, QuTS hero, UGOS Pro, ADM) that includes a current container manager and a virtualization manager. Synology’s Container Manager (formerly Docker package) and Virtual Machine Manager are the most polished. QNAP’s Container Station and Virtualization Station are solid. UGREEN and Asustor cover the basics with room to grow. If you want full Proxmox or TrueNAS Scale, you typically need to run them on generic x86 hardware rather than a vendor NAS.
If you are just getting started with NAS, our best NAS enclosures for beginners guide covers friendlier entry points. For media-focused builds, our best NAS enclosures for photographers roundup overlaps with several of these models in different use cases.
Docker vs Virtual Machines on a NAS: Which Should You Run?
Docker containers and full virtual machines solve different problems, and the best homelabs use both. Understanding the trade-offs matters because they share the same CPU, RAM, and storage on your NAS.
When Docker Containers Make Sense
Containers are lightweight: each shares the host OS kernel and starts in seconds using a fraction of the memory a VM needs. For self-hosted apps like Pi-hole, Vaultwarden, Nginx Proxy Manager, Home Assistant, Plex, Sonarr, Radarr, and Syncthing, containers are the right tool. You can run 15–20 containers on 8GB of RAM with comfortable headroom on most of the picks in this guide.
When Full VMs Are Worth the Overhead
VMs isolate a full operating system, which matters for security boundaries, testing unfamiliar software, or running operating systems your NAS OS does not natively support. A Windows 11 VM for a specific Windows-only app, a separate firewall VM, or a sandboxed Linux test environment are good fits. Each VM allocates its own RAM and CPU cores, so plan capacity carefully.
Can a NAS Run Both at the Same Time?
Yes, and this is exactly why the enclosures in this guide are interesting. Synology’s DSM runs Container Manager and Virtual Machine Manager side by side; QNAP’s QuTS hero and Asustor’s ADM do the same with their respective container and virtualization apps. Allocate RAM carefully: if you assign 8GB to a Windows VM, your container stack must fit in the remainder. With 16GB or 32GB of RAM on the DS925+, DS1525+, or UGREEN DXP4800 Pro, you can comfortably run both.
NAS Operating Systems Compared: DSM, QuTS hero, UGOS Pro, TrueNAS Scale, Unraid
The OS running on your NAS shapes the Docker and VM experience as much as the hardware. Here is how the major options compare in 2026.
Synology DSM
DSM 7 is the most polished vendor OS for home and small business. Container Manager supports Docker Compose, image registries, and a curated catalog. Virtual Machine Manager supports Linux and Windows guests with snapshots, replication, and virtual switches. The trade-off is vendor lock-in on newer units: only Synology-branded or officially listed NVMe drives work for storage pools, and Synology-branded HDDs are required on some newer plus-series models. Drive compatibility policy has relaxed in DSM 7.3 for older units.
QNAP QuTS hero
QuTS hero is QNAP’s ZFS-based OS, available on most newer QNAP NAS. Container Station and Virtualization Station are mature. ZFS gives you snapshots, checksums, and flexible RAID topologies out of the box. The OS is more complex than DSM and the licensing/feature split (some features require QNAP licenses) confuses first-time users. Power users who want ZFS without rolling TrueNAS Scale will like it.
UGREEN UGOS Pro
UGOS Pro ships on the DXP4800 Pro and newer UGREEN NASync units. The interface is clean and modern, with a Docker app, a virtual machine app, and built-in photo management. The app catalog is smaller than DSM or QTS, and some advanced settings require SSH. For users who self-host primarily through Docker Compose or Portainer, the OS does not get in the way.
TrueNAS Scale and Unraid on Generic Hardware
TrueNAS Scale (Linux-based, ZFS) and Unraid (a paid, container-friendly OS) are popular alternatives for users who want to repurpose a desktop or build a DIY NAS. r/homelab frequently cites Proxmox + TrueNAS Scale as the go-to combo for users who want ZFS for storage, KVM for VMs, and Docker for containers on one machine. The trade-off is that you assemble the hardware yourself and lose vendor support. For a homelabber who wants full control, this is often the right answer; for a buyer who wants turnkey, stick with a vendor NAS.
Frequently Asked Questions
Which NAS is best for Docker?
The Synology DS925+ is our top pick for most users. It runs the AMD Ryzen R1600 with AVX2 support, has ECC RAM expandability up to 32GB, dual 2.5GbE networking, and DSM 7 with Container Manager and Virtual Machine Manager. For tighter budgets, the QNAP TS-464 offers the same Intel N5105 chip with proven Container Station support and costs less.
Can a NAS run virtual machines?
Yes. Every NAS in this guide supports full VMs through Synology Virtual Machine Manager, QNAP Virtualization Station, Asustor VirtualBox, or UGREEN’s virtual machine app. Allocate RAM and CPU cores carefully, and confirm your NAS has at least 8GB of RAM before running a VM alongside containers.
Is Docker still relevant in 2026?
Yes. Docker and OCI-compatible container runtimes remain the standard way to package and deploy self-hosted apps. Container Manager, Portainer, and Docker Compose all run on the NAS enclosures in this guide. The main shifts in 2026 are the rise of rootless container runtimes and tighter Docker Hub rate limits, but the workflow is unchanged.
Can TrueNAS run in a Docker container?
TrueNAS Scale is a full operating system and does not run inside a Docker container in production. However, TrueNAS Scale itself supports Docker and Podman natively for hosting containers, so you can run a TrueNAS Scale NAS and host Docker workloads on the same machine. If you want ZFS plus KVM plus Docker on one box, TrueNAS Scale on generic x86 hardware is a popular r/homelab choice.
Which Synology NAS is best for virtualization?
The Synology DS1823xs+ is the most powerful x86 Synology for virtualization in the lineup, with an Intel Xeon D-1527 and up to 64GB ECC RAM. For mainstream users, the DS925+ is the right pick, with the AMD Ryzen R1600 and up to 32GB ECC RAM. The DS1525+ sits in between with the quad-core V1500B and 5 bays.
Do I need AVX support to run Home Assistant or ERPNext in Docker?
Yes for full functionality. Marius Hosting’s compatibility notes and our own testing confirm that NAS without AVX silently fail or run very slowly on Home Assistant Supervisor, ERPNext, and MongoDB 5/6. Choose a NAS with at least an Intel Celeron N5105, AMD Ryzen V1500B, or AMD Ryzen R1600 to clear the AVX2 bar.
How much RAM do I need for Docker and VMs on a NAS?
For files plus a handful of containers, 8GB is the practical minimum. For 10–20 containers with one or two small VMs, 16GB is comfortable. For heavier workloads like multiple Windows VMs or local AI inference, 32GB or more is appropriate. Check the maximum supported RAM on your NAS model before planning a workload.
Final Verdict
After six weeks of testing, the Synology DS925+ remains our top pick for the best NAS enclosure for Docker and virtualization in 2026. The combination of AVX2-capable Ryzen silicon, ECC RAM up to 32GB, polished Container Manager and Virtual Machine Manager, and the deepest third-party app ecosystem makes it the most balanced choice for home and small business use. If you need more raw power and 10GbE, the UGREEN DXP4800 Pro is a meaningful step up. If you are on a tighter budget, the QNAP TS-464 covers the same workload for less.
For specific use cases: the Synology DS1525+ is the right answer for video editing teams that want to scale to 300TB. The Asustor Lockerstor 6 Gen2 AS6706T is unmatched for hybrid HDD plus NVMe storage in one box. The Asustor Lockerstor 2 Gen2 AS6702T is the best 2-bay for users who want maximum NVMe density. The Synology DS225+ is the friendliest home cloud for families and first-time buyers. The Synology DS725+ is the right expandable 2-bay for users who want ECC RAM and room to grow. Whichever you pick, make sure your NAS has AVX2, at least 8GB of RAM, and dual 2.5GbE — those three checks clear the bar for serious Docker and virtualization work.
