Best NAS Under $300 in 2026: 3 Budget Picks

A NAS under $300 is best treated as a reliable, low-power file server: centralized storage, automated backups, photo sync, and direct-play media. The ARM processors in this tier aren’t substitutes for a separate x86 compute node when you need broad Docker support or hardware transcoding.

The three picks here differ in memory, networking, container support, and ease of administration, but all prioritize efficient storage over compute-heavy workloads. Knowing that boundary is the first buying decision. We left out 1 GB models, because 2 GB is the practical floor for current NAS software.

Our Pick: UGREEN DH2300

The UGREEN DH2300 ships with 4 GB of RAM and an 8-core ARM processor, double the memory of the other two picks. UGREEN lists it at $269.99.

• CPU: Rockchip 8-core ARM (A72 and A53 cores)
• Memory: 4 GB LPDDR4X, not expandable
• Storage: 2x 3.5”/2.5” SATA bays
• Network and ports: 1x 1GbE, USB-C, two USB-A, 4K HDMI, NFC
• Power: UGREEN advertises about 10W

Eight cores and 4 GB of memory give the DH2300 more headroom than the quad-core models here for concurrent file transfers, photo thumbnail generation, and media indexing, and less risk of running short of memory under load. HDMI output lets you connect it directly to a display, and NFC makes pairing a phone quick.

Know what it doesn’t do. UGREEN says the DH2300 does not officially support Docker, and UGREEN’s buying guide says it doesn’t run Plex, Jellyfin, or Emby servers. Memory is fixed, networking is a single gigabit port, and UGOS Pro, UGREEN’s NAS operating system, is the youngest OS in this guide, with fewer community guides than QTS or ADM.

If the goal is a file server and photo backup target with 4 GB of memory, the DH2300 is the buy. If you need containers, look at the TS-233 or AS3302T below; for a media server, keep compute on a separate mini PC.

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

The ASUSTOR Drivestor 2 Pro Gen2 (AS3302T v2) is the only pick in this guide with a 2.5GbE port, and it usually costs roughly $280. If your switch and computers support 2.5GbE, it lifts large transfers well beyond the gigabit ceiling of the other two.

• CPU: Realtek RTD1619B, 4-core ARM64, 1.7 GHz
• Memory: 2 GB DDR4, not expandable
• Storage: 2x 3.5”/2.5” SATA bays
• Network and ports: 1x 2.5GbE, 3x USB 3.2 Gen 1
• Rated power: 13.1W in operation, 4.5W with disks hibernating (ASUSTOR)

2.5GbE raises the ceiling for large sequential transfers from about 112 MB/s on gigabit to roughly 280 MB/s. For video projects, photo library syncs, and full-system restores, the difference is immediately useful.

ADM (ASUSTOR Data Master) is a capable NAS OS with a clean interface and regular updates. App Central offers Docker Engine and Portainer CE for ARM64 models including this one (ADM 4.3 or later), so a few light containers are possible within 2 GB of memory. Three USB 3.2 ports give you room for external drives, a UPS connection, or USB dongles, and a built-in AES-256 engine handles encrypted shared folders without loading the CPU.

The limits are the RTD1619B’s modest cores and the fixed 2 GB: no Plex hardware transcoding and no VMs. It costs about $60 more than the TS-233, a fair trade if your network supports 2.5GbE. If you’re still on gigabit, the TS-233 or DH2300 is better value. As with any NAS, keep ADM updated and don’t expose it directly to the internet.

Budget Pick: QNAP TS-233

The QNAP TS-233 is the least expensive pick at roughly $220, and it runs QTS, a mature, actively maintained NAS OS with a real app ecosystem.

• CPU: ARM Cortex-A55, 4 cores, 2.0 GHz
• Memory: 2 GB on board, not expandable
• Storage: 2x 3.5”/2.5” SATA bays
• Network and ports: 1x 1GbE, 1x USB 3.2 Gen 1, 2x USB 2.0
• Rated power: 10.8W typical with drives installed, 3.4W in disk standby (QNAP)

At this price, calibrate expectations. The TS-233 is an excellent file server and backup target: SMB and NFS shares, scheduled backups to USB drives, and Hybrid Backup Sync for other NAS units and cloud storage. QNAP lists volume snapshots for basic data protection. Indexing a large photo library will be slow on 2 GB, but it works.

Container Station is supported too. QNAP lists Docker and LXD support on the TS-233, with at least 1 GB of RAM required, so a few ARM64 containers are realistic as long as you keep the stack light. Its four Cortex-A55 cores run at 2.0 GHz, versus 1.7 GHz on the ASUSTOR’s RTD1619B.

QNAP rates the TS-233 at about 10.8W in typical operation with drives installed. At $0.18 per kWh, that is about $17 a year running around the clock, and less when the disks spin down.

The limits: no Plex hardware transcoding, no Virtualization Station, 2 GB of memory on the board, a single gigabit port, and one USB 3.2 port for expansion. If you need a reliable file server and backup appliance at the lowest practical price, the TS-233 delivers. Keep QTS updated, since QNAP’s security record calls for prompt patching.

How to Choose: Buying Criteria

ARM Workload Boundaries

Every pick here uses an ARM processor. That keeps price and power low, but it sets clear limits:

• Best for file serving, backup, and direct-play media
• ARM64 containers only, on the QNAP and ASUSTOR, and none officially on the UGREEN
• No Plex hardware transcoding
• No practical virtual machines
• Low vendor-rated power, about 10 to 13W in operation

If your NAS is purely a file server and backup target, these models save money and power. If Docker at scale, VMs, or Plex transcoding are requirements, use our full NAS comparison and raise the hardware budget.

RAM: The Hidden Bottleneck

Memory is fixed in every pick, so buy enough for the appliance’s lifetime:

The UGREEN’s 4 GB is comfortable for file serving and basic apps. The 2 GB models are tight but workable for their intended use.

Networking: 1GbE vs 2.5GbE

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

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

The ASUSTOR AS3302T v2 has 2.5GbE; the other two are 1GbE. If you regularly move large files and your network supports 2.5GbE, the improvement is worth paying for.

Software Ecosystem: QTS vs ADM vs UGOS

QNAP QTS (TS-233): Feature-rich but more complex. Container Station works on the TS-233 for light ARM64 containers. QNAP’s security history is weaker, so keep auto-update enabled.

ASUSTOR ADM (AS3302T v2): Clean, capable, regularly updated. Docker Engine and Portainer CE are available in App Central. The app library and community are smaller than DSM’s or QTS’s.

UGREEN UGOS Pro (DH2300): The newest platform, with a modern mobile app and strong photo backup. No official Docker support on this model, and the smallest third-party ecosystem.

Bottom Line

For the most hardware for file storage, the UGREEN DH2300 delivers an 8-core CPU and 4 GB of RAM at a $269.99 list price. Just don’t buy it for Docker or a Plex server.

If 2.5GbE matters, the ASUSTOR AS3302T v2 is the only pick here with it, and it runs light ARM64 containers through Portainer CE.

For the lowest price, the QNAP TS-233 runs QTS with Container Station, gets regular security updates, and has a low vendor-rated power draw.
