Best NAS Enclosures 2026: Five Models for Different Storage Jobs
Quick answer
Choose Synology DS224+ for a compact DSM-based backup and sharing setup, QNAP TS-264-8G for two 2.5GbE links and expansion, or Synology DS423+ if four bays are the main need. TerraMaster F2-223 is an older dual-2.5GbE option to check only with clear current support; Asustor AS3302T is a simple two-bay 2.5GbE household box. These are documented use cases, not speed or reliability tests performed by us.
A NAS enclosure is only one part of a storage plan. Drives, backup destination, network equipment, software support and recovery practice decide whether the system fits. The same model family can also contain materially different generations and memory variants.
Match the NAS to the job
| Model | Starting use | Look elsewhere when… |
|---|---|---|
| Synology DS224+ | Two-bay shared storage | You need four bays or a built-in 2.5GbE link. |
| QNAP TS-264-8G | Two-bay multi-gig and media | You mainly need simple DSM workflows or four hard-drive bays. |
| Synology DS423+ | Four-bay dsm expansion | Two bays are enough or a faster built-in network connection matters more. |
| TerraMaster F2-223 | Two-bay 2.5gbe alternative | You want a readily listed current model with unambiguous regional support. |
| Asustor Drivestor 2 Pro (AS3302T) | Simple 2.5gbe household share | You need x86 software, memory expansion or a four-bay plan. |
Synology DS224+: Two-bay shared storage
The DS224+ makes sense when Synology DSM, file sharing, photo management and backups matter more than a fast single network link. The enclosure ships without drives; two bays also limit expansion choices compared with a four-bay system.
Pros
- Synology documents an Intel Celeron J4125, 2 GB DDR4 memory expandable to 6 GB, and two SATA drive bays for a compact DSM installation.
- DSM supports Btrfs snapshots and Synology’s first-party backup and sharing applications, useful for a household or small team that wants one management interface.
Cons and trade-offs
- Its two network connections are 1GbE, not built-in 2.5GbE; a faster switch alone will not make a single client link multi-gigabit.
- Two bays suit a mirror or other small layout but leave less room for capacity growth than DS423+; check drive compatibility before buying.
Best for: A household or branch-office buyer who values DSM tools in a compact two-drive system.
Choose another if: You need four bays or a built-in 2.5GbE link.
Our recommendation
Start with DS224+ when software workflow is the deciding factor. Price two compatible drives and an external or off-site backup, not just the empty enclosure.

QNAP TS-264-8G: Two-bay multi-gig and media
The exact TS-264-8G specification is relevant for a buyer who already has 2.5GbE networking or wants HDMI and optional expansion. QNAP notes hardware revisions; verify the eight-gigabyte configuration and actual memory/processor on the seller listing.
Pros
- The current TS-264-8G hardware sheet lists two built-in 2.5GbE ports, HDMI, two M.2 slots and a PCIe expansion slot.
- QNAP documents an Intel quad-core x86 CPU and 8 GB DDR4 memory in this exact variant, giving more headroom for simultaneous services than the smallest ARM unit here.
Cons and trade-offs
- A two-bay chassis remains a two-bay chassis even with M.2 and PCIe options; those additions also raise the complete system cost.
- A 2.5GbE result requires capable switch, cabling and client; QNAP’s laboratory throughput figures are not a promise for your home network.
Best for: A small media or multitasking installation with a planned 2.5GbE network.
Choose another if: You mainly need simple DSM workflows or four hard-drive bays.
Our recommendation
Choose TS-264-8G for its ports and expansion options, then check drive, RAM and app compatibility for your exact software tasks.
Synology DS423+: Four-bay dsm expansion
Four drive bays give DS423+ a different planning role from DS224+. The extra slots can support a larger pool or staged drive replacement, but they do not replace a backup and should not be mistaken for included storage.
Pros
- Synology’s exact specification lists four SATA drive bays, Intel Celeron J4125 and two M.2 2280 slots.
- DSM and Btrfs snapshots make it a coherent choice when a small team wants capacity planning and familiar Synology management.
Cons and trade-offs
- The network ports are 1GbE; buyers expecting built-in 2.5GbE should compare another chassis or plan around the network limit.
- Four disks cost more, draw more power and occupy more space than a two-bay setup; unused bays only help when expansion is realistic.
Best for: A home office or small team that needs four drive positions and wants DSM.
Choose another if: Two bays are enough or a faster built-in network connection matters more.
Our recommendation
Pick DS423+ for bay count and DSM, not an unverified performance ranking. Confirm the exact chassis remains available with local warranty and that chosen disks are on the compatibility list.

TerraMaster F2-223: Two-bay 2.5gbe alternative
The F2-223 remains a documented older two-bay alternative rather than a guaranteed current bargain. Its original product-page route now leads to a store error, so verify present stock, firmware support and warranty with the seller before committing a storage workflow.
Pros
- TerraMaster documents an Intel Celeron N4505, 4 GB DDR4 base memory and two 2.5GbE ports on F2-223.
- The manufacturer describes TRAID, snapshots and backup tools, giving buyers configuration choices beyond a basic file share.
Cons and trade-offs
- The former exact product URL no longer resolves in the current manufacturer store; availability and after-sales terms need extra checking.
- As with any two-bay enclosure, redundancy choices are constrained by two drive positions, regardless of network speed.
Best for: A buyer comfortable checking current support who wants two 2.5GbE links in a two-bay Intel model.
Choose another if: You want a readily listed current model with unambiguous regional support.
Our recommendation
Treat F2-223 as a compare-if-available option. Ask for the exact model, firmware support and return terms, and compare the complete drive-and-network cost.

Asustor Drivestor 2 Pro (AS3302T): Simple 2.5gbe household share
The AS3302T is a clearly specified household file and media box with a single 2.5GbE port. Be careful with the suffix: AS3302T v2 is a different Gen2 model with a newer processor.
Pros
- Asustor lists two SATA bays, 2 GB DDR4 and one 2.5GbE port, a useful simple network step above a 1GbE-only box.
- The official product page documents ADM applications, Wake on LAN/WAN and tool-free drive installation for routine home use.
Cons and trade-offs
- The Realtek RTD1296 ARM processor and fixed 2 GB memory give less flexibility for demanding x86-only services or RAM expansion.
- It has no HDMI output and only two drive bays; media users should check their exact server-app and playback requirements.
Best for: A household that mainly wants shares, backups and simple media access over 2.5GbE.
Choose another if: You need x86 software, memory expansion or a four-bay plan.
Our recommendation
Use the exact AS3302T spec sheet, not Gen2/v2 claims, to assess this older model. Confirm app compatibility and current seller support before buying.

NAS buying guide: plan for failure and growth
- Count usable bays and capacity. Two bays often suit a mirrored household volume; four offer more layouts and growth. Subtract the disks needed for redundancy before estimating usable capacity, and allow room for future data.
- Separate redundancy from backup. RAID or TRAID may keep a volume available after a drive failure. It does not protect against accidental deletion, theft, fire, malware or a bad sync. Maintain another copy offline or off site and test restore.
- Check the full network path. A 2.5GbE NAS needs a suitable switch/router and client to benefit a single connection. Dual ports do not automatically double one user’s transfer speed.
- Verify drives and apps. Read each maker’s current compatibility list for drive models and firmware. If you need a container, media server, surveillance package or a particular file system, confirm support on the exact CPU architecture and OS release.
- Budget power and placement. Disk noise, fan noise, heat, ventilation, uninterrupted power and UPS behavior matter for always-on storage. Vendor idle figures do not predict your loaded drives and workload.
- Check support age and variant. F2-223 availability is uncertain from its current store route; AS3302T is distinct from AS3302T v2. Confirm seller warranty, firmware and return window before migrating irreplaceable data.

FAQ
Does RAID count as a backup?
No. Redundancy protects availability under some drive failures; an independent recoverable copy is still needed for deletion, damage and other events.
Do these prices include hard drives?
Manufacturer specifications describe empty enclosures or configurable kits. Check the exact offer; our comparison does not assume drives are included.
Is dual 2.5GbE twice as fast for one computer?
Not by itself. Network topology, link configuration, client support and workload control the result. Compare actual needs before paying for extra ports.
Is AS3302T v2 the same as AS3302T?
No. Asustor publishes separate specifications. This article’s fifth model is the original AS3302T with Realtek RTD1296.
