UGREEN NAS DH4300 Plus 4-Bay Desktop Review 2026

Cloud storage bills creep up every year. Photos, 4K videos, and work files pile faster than any 2TB plan can hold. The UGREEN NAS DH4300 Plus promises a one-time purchase that replaces Google Drive, iCloud, and Dropbox with a private 4-bay box sitting on your desk.

After weeks of hands-on testing in 2026, here is an honest look at whether this beginner-friendly NAS earns its spot in your home office.

In a Nutshell

• Processor and memory: The Rockchip RK3588 8-core ARM chip pairs with 8GB LPDDR4X RAM for smooth multitasking and snappy app loading.
• Storage ceiling: Four hot-swappable bays accept up to 128TB total using 32TB drives, enough for most households for the next decade.
• Networking: A single 2.5GbE port delivers transfer speeds around 280 MB/s, fast enough for 4K editors and photo libraries.
• AI features: The built-in AI photo album handles facial recognition, semantic search, and duplicate cleanup locally, no cloud uploads required.
• Software: UGOS Pro offers a clean dashboard, Docker support, and a growing app store, though it still trails Synology’s polish.
• Best for: First-time NAS buyers, families, content creators, and small home offices wanting a quiet, low-power private cloud.

UGREEN NAS DH4300 Plus 4-Bay Desktop

The DH4300 Plus sits in UGREEN’s value tier, slotting above the 2-bay DH2300 and below the Intel-powered DXP series. It targets buyers who want real storage capacity without the enterprise price tag.

The diskless unit currently sells around $379 to $439, undercutting comparable Synology and Asustor 4-bay units by a healthy margin.

Inside the metal chassis you get an octa-core ARM CPU, 8GB of soldered RAM, a single 2.5GbE LAN, HDMI 2.0 for 4K 60Hz output, and two USB ports for external backups.

UGREEN positions this as a personal cloud, media server, and backup hub rolled into one box. After two weeks of daily use, that pitch mostly holds up.

Unboxing and First Impressions

The retail box is compact and clean. Inside you find the NAS, a 90W external power brick, a Cat 6 Ethernet cable, drive screws, and a small quick-start card. No fluff, no padded marketing inserts.

The chassis feels denser than expected for the price. The front panel uses a brushed dark finish with a subtle UGREEN logo and a soft white LED strip. It does not scream “server rack” which matters if it lives on your desk or living room shelf.

Drive trays slide out with a satisfying click. Tool-less mounting works for 3.5-inch drives, while 2.5-inch SSDs still need four small screws. Setup took roughly 12 minutes from unboxing to web dashboard.

Build Quality and Design

The DH4300 Plus uses a steel inner frame with a plastic outer shell. It weighs around 2.6 kg empty, light enough to move but solid enough to feel premium. The vent pattern on the sides and rear handles airflow without dust traps.

A single 120mm rear fan does the cooling. During idle it spins near silent at roughly 21 dBA. Under sustained 4-drive load it climbs to around 32 dBA, audible but never distracting. This is noticeably quieter than older Synology 4-bay units I have tested.

Ports on the back include the 2.5GbE LAN, HDMI 2.0, one USB-C 3.2, one USB-A 3.2, and the DC power input. The lack of a second LAN port is the most obvious omission at this price.

Performance and Real-World Speeds

Over the 2.5GbE link, large-file transfers averaged 278 MB/s read and 264 MB/s write using two Seagate IronWolf 8TB drives in RAID 1. Smaller mixed workloads dropped to around 180 MB/s, still well above what 1GbE NAS units deliver.

The Rockchip RK3588 handled six concurrent Plex streams without breaking a sweat, including one 4K HEVC transcode using hardware acceleration. Photo indexing across a 45,000-image library finished in roughly 9 hours, with face grouping running quietly in the background.

Power draw measured between 5 watts in standby and 32 watts under full disk activity. That translates to under $40 per year in electricity for typical home use, a strong argument over paying monthly cloud fees.

UGOS Pro Software Experience

UGOS Pro is the heart of the device. The dashboard borrows visual cues from Synology DSM but feels lighter and a bit more colorful. Navigation is intuitive enough that my non-technical partner set up her own user account and shared folder without help.

The built-in apps cover the essentials: Files, Photos, Drive, Sync, Backup, Docker, and a Plex installer. The AI photo album is the standout, offering semantic search like “beach sunset” and automatic duplicate detection that actually works.

The app store remains thinner than competitors. Third-party titles like Jellyfin, Immich, and Home Assistant install via Docker, but native packages are still catching up. Power users should expect to spend time in the command line.

Storage, Backup, and Data Protection

Four hot-swap bays support up to 32TB drives each, totaling 128TB raw capacity. The system supports RAID 0, 1, 5, 6, 10, JBOD, and UGREEN’s own SHR-style flexible array. Most home users will land on RAID 5 for the right balance of space and redundancy.

Backup options are generous. Time Machine works natively for Mac users, while Windows clients use the included UGREEN Backup tool or standard SMB. Cloud sync ties into Google Drive, OneDrive, Dropbox, and S3-compatible buckets for 3-2-1 backup strategies.

Snapshot support and Btrfs filesystem options arrived in a 2026 firmware update, addressing an early complaint. Encrypted shared folders use AES-256 with hardware acceleration, keeping access fast even on this ARM chip.

AI Photo Album and Media Features

The AI features run entirely on-device, which matters for privacy. Face recognition grouped family members accurately after about 50 tagged samples. Object search returned solid results for common queries like “dog,” “mountain,” and “birthday cake.”

HDMI 2.0 output supports 4K 60Hz playback directly to a TV, turning the NAS into a basic media box without needing Plex. The remote control is sold separately, which feels like an upsell given the feature is advertised front and center.

Plex Media Server runs as an official app and handles 1080p transcoding well, though 4K HEVC to 1080p transcodes can stutter under heavy library scans. Direct play remains the safer route for 4K content creators.

Mobile App and Remote Access

The UGREEN NAS mobile app covers iOS and Android. It handles file browsing, photo auto-backup, and remote streaming through UGREEN’s relay service. No port forwarding is required, which is a real win for non-technical users.

Auto photo backup worked reliably during testing, uploading roughly 1,200 phone photos overnight. The interface is clean but occasionally slow to refresh thumbnails on older Android devices.

Remote streaming of 1080p video over a 50 Mbps upload connection played smoothly. 4K remote streaming is hit or miss and depends heavily on your home internet upload speed.

Downsides and Who Should Skip It

The single 2.5GbE port is the biggest hardware flaw. There is no upgrade path to 10GbE, which limits professional video editors and multi-user offices. A dual-LAN design at this price would have been welcome.

UGOS Pro is improving fast but still trails Synology DSM in third-party app variety and documentation depth. Users wanting Surveillance Station-grade camera support or advanced virtualization should look elsewhere.

This NAS is not for: enterprise users, heavy 4K transcoding workflows, Windows Server replacements, or anyone planning to run multiple VMs. It is squarely a home and small-office machine.

The 8GB RAM is soldered and not upgradeable. While plenty for current workloads, this caps future-proofing for memory-hungry containers down the road.

Pricing and Value Verdict

At roughly $379 diskless, the DH4300 Plus delivers four bays, 2.5GbE, and 8GB RAM for less than a comparable Synology DS423 with similar specs costs at $499. Over five years it pays for itself versus a 2TB iCloud plan, and you get four times the capacity.

The included two-year warranty is standard for the category. UGREEN’s support response time during my testing averaged under 24 hours via email, which is reasonable for a value-tier product.

For first-time buyers and families moving away from cloud subscriptions, the value math is straightforward. Power users chasing maximum flexibility should budget for the Intel-based DXP4800 instead.

Expert FAQs

Does the UGREEN DH4300 Plus support Plex 4K transcoding?

Yes, the Rockchip RK3588 offers hardware-accelerated decoding for H.264 and HEVC. Direct play of 4K content works flawlessly. Transcoding 4K to 1080p runs but can stutter under heavy library activity. Direct play remains the recommended setup for 4K media libraries.

Can I upgrade the RAM in the DH4300 Plus?

No. The 8GB LPDDR4X RAM is soldered to the motherboard. This keeps costs down but limits future expansion. For most home users running file sharing, photo backup, and Plex, 8GB handles the load comfortably without swapping.

Is the DH4300 Plus loud enough to disturb a bedroom?

In idle states the unit registers around 21 dBA, quieter than most laptop fans. Under heavy disk load it reaches 32 dBA, similar to a soft whisper. Most users find it acceptable for living rooms, though light sleepers may prefer a closet or office placement.

Does it work with Time Machine for Mac backups?

Yes. UGOS Pro includes a native Time Machine setting in the control panel. Create a dedicated shared folder, enable Time Machine support, and your Mac discovers it automatically over the network. Backups run reliably in the background.

Can I access my files remotely without port forwarding?

Yes. UGREEN’s relay service handles remote access through the mobile app and web portal. No router configuration is required. For power users wanting faster direct connections, port forwarding and dynamic DNS are also supported.

What drives are compatible with the DH4300 Plus?

The unit accepts standard 3.5-inch SATA HDDs and 2.5-inch SATA SSDs up to 32TB per bay. NAS-rated drives like Seagate IronWolf, WD Red Plus, and Toshiba N300 are officially recommended for 24/7 reliability and vibration tolerance.

How does it compare to Synology DS423?

The DH4300 Plus offers faster networking with 2.5GbE versus the DS423’s 1GbE, more RAM at 8GB versus 2GB, and a lower price. Synology’s DSM software remains more polished with a larger app catalog. UGREEN wins on hardware value, Synology on software maturity.

Does it support Docker and self-hosted apps?

Yes. UGOS Pro includes a Docker container manager with a graphical interface. Popular self-hosted apps like Immich, Jellyfin, Nextcloud, Home Assistant, and Pi-hole run well within ARM-compatible image limits.
