Synology DS923+ vs UGREEN NASync DXP4800 Plus

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Synology DS923+ comes out ahead by a narrow margin (4.6 vs 4.4). The gap is mostly about Home and small-office users who prioritize the most polished, reliable NAS software and a deep app ecosystem over raw hardware specs. — read the strengths below before deciding.

Higher ratedRanked #1 in Best 4-Bay NAS Drives

Synology DS923+

4.6

$639.99as of Jun 7

The Synology DS923+ remains the safe default 4-bay NAS thanks to DSM, the most mature operating system in the category, and a deep app ecosystem. StorageReview measured strong RAID-5 throughput and sustained 1,000+ MB/s once a 10GbE module is added. Its weak spots are dated networking (dual 1GbE stock) and a modest CPU, but for households who want it to just work, it is still the most recommended pick.

Strengths

— DiskStation Manager (DSM) is the most polished, mature NAS OS available
— Deep, well-supported app library for backup, sync, photos and surveillance
— Two built-in M.2 NVMe slots for SSD caching or a storage pool

Watch-outs

— Ships with only dual 1GbE ports; 2.5GbE rivals beat it out of the box
— AMD Ryzen R1600 is an older, modest dual-core CPU
— NVMe storage-pool support is limited to Synology-branded drives

Ranked #2 in Best 4-Bay NAS Drives

UGREEN NASync DXP4800 Plus

4.4

$619.99as of Jun 7

The UGREEN NASync DXP4800 Plus is the clearest value proposition in the category, pairing a 12th-gen Intel Pentium Gold 8505 with 10GbE and 2.5GbE networking and 8GB of DDR5 out of the box. ITPro found it among the fastest enclosures it tested on ATTO benchmarks. The catch is UGOS, which reviewers agree is improving fast but still trails the maturity of Synology and QNAP software.

Strengths

— 10GbE plus 2.5GbE networking included out of the box
— 12th-gen Intel Pentium Gold 8505 5-core CPU is far faster than rivals' chips
— 8GB DDR5 RAM, expandable to 64GB for VMs and containers

Watch-outs

— UGOS software is less mature than Synology DSM or QNAP QTS
— Newer vendor with a shorter track record in NAS
— App ecosystem still trails the established players

How they stack up

Synology DS923+

The DS923+ wins on software maturity over the UGREEN NASync DXP4800 Plus and QNAP TS-464, but its stock dual 1GbE networking trails the 2.5GbE on the QNAP and TerraMaster F4-424 Pro and the 10GbE on the UGREEN and Asustor Lockerstor 4 Gen3. Its CPU is older and weaker than every rival here.

UGREEN NASync DXP4800 Plus

The DXP4800 Plus is the hardware-value leader, beating the Synology DS923+ and QNAP TS-464 on CPU and including 10GbE that the DS923+ charges extra for. It costs far less than the Asustor Lockerstor 4 Gen3 while offering similar 10GbE, and its DDR5 CPU outclasses the TerraMaster F4-424 Pro's, though its UGOS software is less polished than all of them.
