Best NAS Under $300 in 2026: Budget Picks Tested

A NAS under $300 can do more than store files. At the top of this budget, you get an Intel x86 CPU that runs Docker containers, transcodes Plex streams, and handles Home Assistant — a genuine home server for the price of a nice dinner out. At the bottom, you get a reliable always-on file server that backs up every device in your house while sipping 8 watts.

The catch: this price range spans two completely different categories of hardware. The x86 NAS devices (Intel Celeron J4125) run circles around ARM-based models for compute tasks, but they cost $300 and up. ARM NAS devices ($170–$283) are cheaper and more power-efficient, but they can’t run Docker, can’t transcode video, and can’t be upgraded. Knowing which camp you need to be in is the first decision.

We tested five NAS devices under (or near) $300, focusing on what matters at this price: what you can actually do with the hardware, how far you can push it, and where the walls are.

Our Pick: Synology DS224+

Important update: The Synology DS224+ has been discontinued and its price has inflated to ~$870 — well beyond the $300 budget. At its original ~$300 MSRP, it was the obvious pick as the only sub-$300 x86 NAS. If you can find one at or near its original price, it remains an excellent buy. At ~$870, skip it entirely and consider the DS225+ at ~$335 (just over budget) or the ARM-based options below.

The Synology DS224+ at its original ~$300 was the obvious pick: it was the only NAS under $300 with an x86 Intel CPU. That single fact unlocks Docker, Plex hardware transcoding, virtual machines, and the entire x86 software ecosystem. Every other NAS in this guide is ARM-based, and that means every other NAS in this guide has hard limits on what it can run.

Specs: Intel Celeron J4125 (4C/4T, 2.7 GHz) · 2 GB DDR4 (expandable to 6 GB) · 2x 3.5”/2.5” SATA · 2x 1GbE · 2x USB 3.2 Gen 1

Idle Power: ~15W · Price: ~$870 (discontinued — inflated; originally ~$300)

The J4125’s Intel Quick Sync engine handles 3–4 simultaneous 1080p Plex transcodes. Container Manager (DSM’s Docker interface) runs lightweight containers — Pi-hole, Home Assistant, Nginx Proxy Manager, Vaultwarden — on the stock 2 GB RAM, though you should immediately add a 4 GB SO-DIMM ($15) to bring it to 6 GB. At 6 GB, you comfortably run 3–5 Docker containers alongside the NAS OS. For a deeper Docker comparison, see our best NAS for Docker guide.

DSM 7 is the reason people pay the Synology premium. Automatic security updates, a built-in firewall with per-app rules, Synology Drive for file sync, Synology Photos for photo management, Active Backup for Business for PC/server backups — all included, all polished, all maintained. The ecosystem means you need fewer Docker containers because DSM’s native apps handle what would otherwise require Nextcloud, Immich, and Duplicati.

Two 1GbE ports with link aggregation support provide redundancy and marginal throughput improvement for multi-client access. It’s not 2.5GbE, but at this price, you’re choosing between the DS224+‘s x86 CPU and the ASUSTOR’s 2.5GbE — and the CPU matters more.

The DS224+ is being superseded by the DS225+ (~$335), which adds a 2.5GbE port but keeps the same J4125 CPU. If you can stretch ~$40 over budget, the DS225+ is the smarter long-term buy. If $300 is firm, the DS224+ loses nothing but the faster port. See our 2-bay NAS comparison for a detailed breakdown.

Best Value: UGREEN DH2300

The UGREEN DH2300 ships with 4 GB of RAM and an 8-core processor for ~$200. Read that again — double the RAM of the Synology, at a fraction of the price. For pure file serving and media storage, no NAS under $300 delivers more hardware per dollar.

Specs: Rockchip RK3576 (8-core ARM) · 4 GB LPDDR4X · 2x 3.5”/2.5” SATA · 1x 1GbE · USB-A + USB-C 3.2 · HDMI 2.1 · NFC

Idle Power: ~10W · Price: ~$200

The RK3576’s eight ARM cores handle concurrent file transfers, photo thumbnail generation, and media indexing without the sluggishness that plagues dual-core and quad-core ARM NAS devices. The 4 GB RAM means UGOS Pro runs comfortably with headroom for background tasks — you won’t see the constant swapping that the 2 GB models suffer under moderate load.

HDMI 2.1 output turns the DH2300 into a direct-play media box. Connect it to a TV, install Kodi or a media player app, and play content directly without streaming over the network. No other NAS in this guide has HDMI at this price point (the QNAP TS-233 doesn’t have one).

UGOS Pro is the trade-off. UGREEN’s NAS operating system is improving rapidly — Docker Engine support, Tailscale integration, and a solid mobile app have all landed in recent updates — but it’s still the youngest NAS OS in this guide. The app library is smaller than QTS or DSM. Third-party community resources are thinner. If a problem arises, you’ll find fewer forum threads and guides than you would for a Synology.

The critical limitation: ARM architecture. Despite the impressive specs on paper, the RK3576 cannot run standard x86 Docker images. There’s limited container support via ARM-compatible images, but the vast majority of the self-hosted Docker ecosystem targets x86. No Plex transcoding. No VMs. If “NAS as a home server” is your goal, you need to spend ~$300 on the DS224+. If “NAS as a file server with great hardware” is the goal, the DH2300 at ~$200 is the buy.

Best 2.5GbE Under $300: ASUSTOR Drivestor 2 Pro Gen2

The ASUSTOR Drivestor 2 Pro Gen2 (AS3302T v2) is the only NAS under $300 with a 2.5GbE port. If your home network runs at 2.5GbE — and many do in 2026, since most new routers and switches include it — this NAS saturates that link where every other sub-$300 model tops out at 1GbE.

Specs: Realtek RTD1619B (4-core ARM, 1.7 GHz) · 2 GB DDR4 · 2x 3.5”/2.5” SATA · 1x 2.5GbE · 3x USB 3.2 Gen 1

Idle Power: ~13W · Price: ~$283

Real-world 2.5GbE transfers hit ~280 MB/s reading from a RAID 1 array with spinning drives. That’s more than double the ~112 MB/s ceiling on 1GbE models. For large file transfers — video editing proxies, photo library syncs, full-system backup restores — the speed difference is immediately noticeable.

ADM (ASUSTOR Data Master) is a capable Linux-based NAS OS with Docker-like app support via its App Central. The interface is clean, updates are regular, and ASUSTOR’s security track record is solid. Three USB 3.2 ports (versus the typical one or two) provide flexibility for external drives, UPS connections, or USB dongles.

The RTD1619B ARM CPU is the limiting factor. Same silicon as the TerraMaster F2-212, same inability to run Docker or transcode video. At ~$283, you’re paying a ~$64 premium over the QNAP TS-233 specifically for the 2.5GbE port and the extra USB ports. That’s a fair trade if your network supports it. If you’re still on 1GbE, the QNAP at ~$219 or the UGREEN at ~$200 offer better value.

AES-256 hardware encryption means you can encrypt shared folders with minimal performance impact — the crypto engine handles it without loading the CPU. BTRFS support provides snapshots for data protection, and the 4 free Surveillance Station camera licenses are a bonus if you’re running IP cameras.

Budget Pick: QNAP TS-233

The QNAP TS-233 at ~$219 is the cheapest NAS from a major brand that you should consider buying. Below this price, you’re looking at no-name hardware with questionable software support and no security updates. The TS-233 runs QTS — a mature, actively maintained NAS OS with a real app ecosystem.

Specs: ARM Cortex-A55 (4-core, 2.0 GHz) · 2 GB DDR4 · 2x 3.5”/2.5” SATA · 1x 1GbE · 1x USB 3.2 Gen 1 + 2x USB 2.0

Idle Power: ~8W · Price: ~$219

At this price, calibrate expectations. The TS-233 is an excellent file server and backup target. SMB/NFS file shares work perfectly. Scheduled Rsync backups to external USB drives work. QTS’s photo and media indexing runs — slowly, but it runs. Hybrid Backup Sync handles cloud backup to Backblaze B2, AWS S3, or Azure. Snapshot support on ext4 provides basic data protection.

The Cortex-A55 at 2.0 GHz is meaningfully faster than the 1.7 GHz RTD1619B in the TerraMaster and ASUSTOR. For file serving, photo indexing, and backup operations, that clock speed difference translates to noticeably snappier response times in the QTS interface.

8W idle power means the TS-233 costs roughly $8–10 per year in electricity running 24/7 (at $0.12/kWh). For a backup server that’s always on but rarely under heavy load, that’s as cheap as it gets.

The walls: no Docker, no Plex transcoding, no VMs. The 2 GB RAM is soldered — you can never upgrade it. Single 1GbE limits throughput. Only one USB 3.2 port for expansion. If any of these limitations matter to you now or in the future, consider stretching to the DS225+ at ~$335 for x86 and Docker support. The DS224+ at its original ~$300 was the natural upgrade, but its discontinued pricing of ~$870 makes it a non-starter. If you genuinely need a reliable file server and backup appliance at the lowest possible price, the TS-233 delivers.

Worth the Stretch: Synology DS225+

The Synology DS225+ at ~$335 is technically ~$35 over our $300 threshold, but it deserves special mention now that the DS224+ has been discontinued with inflated pricing. The DS225+ is effectively the cheapest x86 NAS you can buy, and the pitch is simple: everything the DS224+ does, plus a 2.5GbE port.

Specs: Intel Celeron J4125 (4C/4T, 2.7 GHz) · 2 GB DDR4 (expandable to 6 GB) · 2x 3.5”/2.5” SATA · 1x 1GbE + 1x 2.5GbE · 2x USB 3.2 Gen 1

Idle Power: ~17W · Price: ~$335

The 2.5GbE port replaces one of the DS224+‘s dual 1GbE ports, giving you one 2.5GbE and one 1GbE. If your primary workstation has a 2.5GbE NIC (most modern motherboards do), file transfers jump from ~112 MB/s to ~280 MB/s. For daily use — syncing project folders, transferring photos, pulling media files — that’s a quality-of-life upgrade you notice every time.

Same J4125 CPU, same RAM expandability to 6 GB, same DSM 7 ecosystem. Docker works. Plex transcoding works (with a caveat: the DS225+ removed the i915 GPU driver that the DS224+ had, which limits some hardware transcoding scenarios — check our Plex NAS guide for details). Everything in the DSM ecosystem transfers directly.

The honest question: is 2.5GbE worth ~$35? If your network supports it — yes, without hesitation. And with the DS224+ now discontinued and selling at inflated prices around ~$870, the DS225+ is effectively the only current-generation Synology 2-bay worth buying. There is no cheaper Synology alternative anymore.

A Note on the TerraMaster F2-212

We tested the TerraMaster F2-212 (~$170) but can’t recommend it over the other options in this guide. Note: The F2-212 is currently unavailable from most retailers. The RTD1619B ARM CPU is the same silicon as the ASUSTOR AS3302T — but the F2-212 ships with just 1 GB of RAM (soldered, non-expandable), a single 1GbE port, and no 2.5GbE. TOS runs on 1 GB, but barely — the interface lags, background indexing slows to a crawl, and there’s no headroom for anything beyond basic file serving.

At $170, the QNAP TS-233 ($219) gives you double the RAM and QTS for a similar price. The UGREEN DH2300 (~$200) gives you quadruple the RAM and an 8-core CPU for ~$20 more. The F2-212 sits in an awkward middle where it costs more than the cheapest option while delivering less capability than the slightly more expensive ones.

How to Choose: Buying Criteria

x86 vs ARM: The Defining Decision

This is the single most important choice in the sub-$300 NAS market:

x86 (Intel J4125) — Synology DS224+/DS225+:

• Runs Docker containers (Pi-hole, Home Assistant, Jellyfin, Nextcloud)
• Hardware transcodes Plex/Jellyfin via Intel Quick Sync
• Can run lightweight virtual machines
• Compatible with virtually all NAS software
• Costs $300–$335

ARM (Cortex-A55, RTD1619B, RK3576) — Everything else:

• File serving, backup, and media direct-play only
• No Docker (or very limited ARM-compatible images on UGREEN)
• No hardware video transcoding
• Lower power consumption (8–13W vs 15–17W)
• Costs ~$170–$230

If you plan to self-host anything beyond file storage — even one Docker container, even basic Plex transcoding — you need the DS224+ or DS225+. There is no ARM workaround. If your NAS is purely a file server and backup target, the ARM models save money while drawing less power.

RAM: The Hidden Bottleneck

Every NAS in this guide ships with inadequate RAM for its capabilities:

The DS224+/DS225+ are the only budget NAS devices with expandable RAM. A 4 GB DDR4 SO-DIMM costs $15 and takes five minutes to install. This is a must-do upgrade on day one — the difference between 2 GB and 6 GB is the difference between a NAS that hesitates and one that responds instantly.

The UGREEN DH2300 ships with 4 GB and can’t be upgraded, but 4 GB is adequate for file serving and basic apps. Every other ARM model is stuck at 2 GB (or 1 GB for the F2-212), which is tight but workable for their intended use cases.

Networking: 1GbE vs 2.5GbE

At this price range, you’re choosing between 1GbE (~112 MB/s) and 2.5GbE (~280 MB/s). The practical impact depends on your workload:

• Small file transfers (documents, code repos): No difference. Both feel instant.
• Large file transfers (video, photos, backups): 2.5GbE cuts wait times by 60%. A 50 GB backup takes 7.5 minutes on 1GbE vs 3 minutes on 2.5GbE.
• Media streaming: Even 4K HDR remuxes (80+ Mbps) are well within 1GbE. You don’t need 2.5GbE for streaming.
• Multi-client access: 1GbE becomes a bottleneck faster when multiple users access the NAS simultaneously.

The ASUSTOR AS3302T v2 ($283) and Synology DS225+ ($335) have 2.5GbE. Everything else is 1GbE. If you regularly transfer large files and your network supports 2.5GbE, the speed improvement is real and noticeable.

Software Ecosystem: DSM vs QTS vs ADM vs UGOS

Synology DSM (DS224+, DS225+): Best overall. Most polished UI, strongest security track record, best first-party apps (Drive, Photos, Active Backup). Largest community. Most Docker guides written for DSM.

QNAP QTS (TS-233): Feature-rich but more complex. Container Station is excellent (though irrelevant on the ARM TS-233). Slightly weaker security history — keep auto-update enabled.

ASUSTOR ADM (AS3302T): Clean, capable, regularly updated. Smaller app library and community than DSM or QTS. Solid for core NAS functions.

UGREEN UGOS Pro (DH2300): Newest, most rapidly improving. Modern mobile app, Docker Engine support, Tailscale integration. Smallest third-party ecosystem. Best suited for users comfortable with less hand-holding.

Bottom Line

The Synology DS224+ was the best NAS under $300 at its original ~$300 price, but it has been discontinued and now sells for ~$870. If you find one at its original price, grab it. Otherwise, stretch to the Synology DS225+ at ~$335 for the same x86 J4125 CPU, Docker support, and DSM ecosystem plus 2.5GbE.

For the best hardware per dollar without x86 requirements, the UGREEN DH2300 at ~$200 delivers an 8-core CPU and 4 GB RAM — the most capable file server at this price.

If 2.5GbE networking matters on an ARM NAS, the ASUSTOR AS3302T v2 at ~$283 is the only sub-$300 option with it.

For the absolute cheapest reliable NAS, the QNAP TS-233 at ~$219 runs QTS, gets security updates, and idles at 8W.

And if you can stretch to ~$335, the Synology DS225+ is now the default x86 recommendation — adding 2.5GbE to the DS224+‘s winning formula at a price that’s actually available.
