A NAS enclosure typically costs $150–$800 for home use, with drives adding $60–$400 each depending on capacity.
If you’re wondering how much does a NAS cost, the honest answer is that the box is only half the story. Most prices you see — the $299 Synology, the $550 QNAP — cover the diskless enclosure alone. Add hard drives, and your real investment lands between $500 and $1,500 for a typical home setup. That’s a wide range, and this guide breaks down exactly where your money goes and what you actually need.
What Drives the Price of a NAS?
NAS pricing scales with four main factors: bay count, processor class, memory, and networking speed. A 2-bay unit with a modest CPU and 1GbE networking sits at the low end; a 6-bay rackmount with 10GbE and ECC RAM costs several times more.
You’re also paying for the software ecosystem. Synology’s DiskStation Manager (DSM) and QNAP’s QTS are mature app platforms that handle backup, media streaming, and Docker containers — and that polish is part of why these brands command a premium over bare-bones alternatives.
- Entry level (2-bay): $150–$350. Fine for basic backup and light streaming.
- Mid-range (4-bay): $400–$700. The sweet spot for home media and Plex.
- Prosumer (5–6 bay): $650–$1,000. Room to grow and stronger CPUs.
- SMB/rackmount: $1,200–$4,500+. Hot-swap bays, redundant PSUs, 10GbE.
Current Model Prices: What You’ll Actually Pay
The table below shows real retail prices from current listings, all for the enclosure only — drives are separate.
| Model | Bays | Street Price |
|---|---|---|
| Synology DS224+ | 2 | $299.99 |
| Synology DS423+ | 4 | ~$500 |
| Synology DS925+ | 4 | ~$640 |
| Synology DS1525+ | 5 | ~$800 |
| QNAP TS-264 | 2 | ~$350–$450 |
| QNAP TS-464 | 4 | ~$550 |
| UGREEN NASync DXP4800 Plus | 4 | $656.99 |
| TerraMaster F4-424 Pro | 4 | $687.99 |
| Ubiquiti UniFi UNAS Pro | 7 | $499 |
| Asustor Flashstor 6 Gen2 | 6 (NVMe) | ~$999 |
Three trends stand out. Synology and QNAP dominate the mid-range with strong software ecosystems, UGREEN and TerraMaster undercut them on price-per-bay with newer hardware, and the Asustor Flashstor line trades traditional drive bays for all-NVMe storage at a premium.

Don’t Forget the Drives: The Hidden Cost
The most common mistake is treating the diskless price as the total. Drives routinely rival or exceed the enclosure cost.
Here’s what realistic configurations actually cost:
That RAID 1 setup gives you 8 TB of mirrored storage — one drive can fail without losing data. The 4-bay example with 24 TB usable typically runs four drives in a RAID 5 or SHR configuration.
Which NAS Should You Buy?
Match the device to what you’ll actually do with it, not what looks impressive on paper.
Stick with a 2-bay unit if you need simple backup, file sharing across a home network, and maybe one or two streaming streams. Move up to a 4-bay if you run Plex with multiple users, want room to expand, or plan to keep this device for five-plus years — 4-bay models are often the better long-term value, and Wirecutter’s NAS testing reaches a similar conclusion for most home buyers.
Three more things to check before you buy:
- Networking: Entry models ship with 1GbE, which tops out around 110 MB/s. If you transfer large files regularly, 2.5GbE (now common on mid-range units) is worth the upgrade.
- Drive compatibility: Vendors publish compatibility lists and may restrict certain SATA drives by model. Check before buying.
- App ecosystem: Confirm the device runs the apps you need — DSM and QTS both support Docker, backup tools, and media servers, but not identically.
Wired’s coverage of the best NAS devices highlights the same core advice: buy for your workload, not the spec sheet.
