Best NAS for Home Servers in 2026

Quick Recommendation

For most self-hosters, buy a Synology DS425+. At $520–595 (diskless, depending on retailer), it runs Docker natively via Container Manager, has Intel Quick Sync for Plex transcoding, supports NVMe caching, and Synology’s DSM software is the most polished NAS OS on the market. Pair it with two 8 TB Seagate IronWolf drives ($160 each) in SHR (Synology Hybrid RAID) for 8 TB usable, fault-tolerant storage at about $840–915 total.

Want 2.5 GbE built in? The newer Synology DS925+ (~$620, AMD Ryzen Embedded V1500B, 4 GB ECC RAM expandable to 32 GB) adds dual 2.5 GbE ports. It can’t hardware-transcode video like the Intel-based DS423+, but the quad-core/8-thread V1500B is roughly 47% faster in multi-threaded tasks than the DS923+‘s dual-core R1600 — a meaningful upgrade for Docker-heavy setups. Note: the DS925+ drops the PCIe expansion slot, so 10 GbE is no longer an option on this model.

If you want maximum control and flexibility, build a DIY NAS with TrueNAS SCALE or Unraid. You’ll get more hardware for your money, but you’ll spend more time configuring it. See our DIY NAS Build Guide.

What to Look For

Drive Bays

More bays = more storage and better redundancy options. Here’s the practical breakdown:

• 2-bay: 4–36 TB usable (with RAID 1 / SHR-1). Good for getting started. Limited expansion.
• 4-bay: 8–72 TB usable (with RAID 5 / SHR-1). The sweet spot for most home users. Lose one drive without data loss.
• 6+ bay: For serious storage needs. Supports RAID 6 / SHR-2 (survive two simultaneous drive failures).

Our recommendation: Start with 4 bays. You can fill two now and add two later.

CPU

The CPU determines whether your NAS can run Docker containers, transcode video, and handle encryption without slowing to a crawl.

• Intel (with Quick Sync): Required for Plex/Jellyfin hardware transcoding. Synology DS423+ and DS224+ both have Intel CPUs with Quick Sync.
• AMD: Better raw compute per watt, but no hardware transcoding. Synology DS923+ uses AMD Ryzen — great for everything except Plex transcoding.
• ARM: Cheap Synology models (DS120j, DS220j) use ARM chips. Avoid these for self-hosting — too slow for Docker containers and zero transcoding support.

RAM

• 2 GB: Barely enough for the NAS OS. Don’t run Docker on this.
• 4 GB: Minimum for light Docker use (Pi-hole, a few small containers).
• 8+ GB: Recommended. Lets you run a full Docker stack comfortably. Synology models are upgradeable — buy the base config and add RAM yourself for half the cost.

Networking

• 1 GbE: Standard. Fine for streaming and normal file access. Bottleneck for large file transfers.
• 2.5 GbE: The new standard. Synology DS925+ has it built in. Otherwise, add it via USB adapter.
• 10 GbE: Overkill for most homes. Matters for video editing or multi-user environments. Available via PCIe expansion on DS923+ and DS1621+.

Docker Support

Not all NAS devices support Docker. Synology runs Docker via Container Manager (formerly Docker package). QNAP runs Docker via Container Station. TrueNAS SCALE runs Docker natively on Linux. TrueNAS CORE (FreeBSD) does NOT run Docker — it uses jails.

Power Consumption and Running Costs

NAS power consumption depends heavily on the number and type of drives installed:

Configuration	Idle (W)	Annual Cost ($0.12/kWh)
DS224+ with 2x HDD	~18 W	$18.92
DS425+ with 4x HDD	~30 W	$31.54
DS923+ with 4x HDD	~32 W	$33.64
DIY 8-bay with 8x HDD	~50–70 W	$52.56–73.58
Each additional HDD	+5–8 W	+$5.26–8.41
SSD instead of HDD	-3–5 W per drive	Saves $3.15–5.26/year/drive

Tip: Enable HDD hibernation for drives that aren’t accessed frequently. A 4-bay NAS with two drives sleeping drops from 30W to 20W.

FAQ

Should I buy a Synology or build my own?

Buy a Synology if you value your time and want everything to “just work.” Build your own if you want maximum storage per dollar, ZFS, or specific hardware requirements. The DS425+ at ~$520–595 is hard to beat for convenience. A DIY 8-bay build costs $400–600 (without drives) but gives you twice the capacity and more powerful hardware.

How many drives should I start with?

Start with two drives in a 4-bay NAS. Use SHR/RAID 1 for redundancy (you get one drive’s worth of usable space). Add more drives as you need them. Starting with two 8 TB IronWolf drives gives you 8 TB usable for ~$320.

Do I need a NAS if I have a mini PC?

They complement each other. Use a mini PC for compute (Docker containers, VMs, transcoding) and a NAS for bulk storage (media, backups, photos). Connect them over your LAN with NFS or SMB mounts. This separation is cleaner and more reliable than trying to do everything on one device.

Which drives should I buy?

See our Best Hard Drives for NAS guide. Short answer: Seagate IronWolf or WD Red Plus in 8–16 TB capacities for the best price per TB.

What’s the 3-year cost of owning a NAS?

Here’s the full cost picture including drives (4x 8 TB IronWolf at ~$160 each) and electricity ($0.12/kWh):

Setup	Hardware	3-Year Power	3-Year Total
DS224+ (2x 8 TB)	$690	$50	$740
DS425+ (4x 8 TB)	$1,200	$79	$1,279
DS925+ (4x 8 TB)	$1,260	$84	$1,344
DIY TrueNAS N305 (4x 8 TB)	$1,100	$63	$1,163
DIY TrueNAS N305 (8x 8 TB)	$1,780	$110	$1,890
Unraid + used Dell Optiplex (4x 8 TB)	$920	$95	$1,015

Note: HDD prices have risen ~46% since late 2025 due to AI datacenter demand (see our Best NAS Hard Drives guide). These costs reflect early 2026 pricing and may increase further.

The DIY TrueNAS route saves $100–200 over Synology at 4 bays and significantly more at 8+ bays. But factor in your time — a Synology setup takes 20 minutes, TrueNAS takes hours the first time.

DS425+ or DS925+ — which should I buy?

• DS425+ (~$520–595) if you run Plex or Jellyfin — its Intel J4125 has Quick Sync hardware transcoding that the DS925+‘s AMD V1500B lacks entirely. It also includes a 2.5 GbE port now.
• DS925+ (~$620) if you prioritize Docker performance, need dual 2.5 GbE, or want more RAM for heavy container workloads — its quad-core/8-thread CPU is ~47% faster than the DS923+‘s R1600 in multi-threaded tasks. Also supports ECC RAM up to 32 GB.
• DS923+ (~$600) only if you specifically need the PCIe slot for a 10 GbE NIC — the DS925+ dropped it
