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 4.3). The gap is mostly about households and prosumers who want the least-friction NAS experience and value mature software over raw hardware spec — read the strengths below before deciding.

The DS923+ is the default 4-bay NAS recommendation for most users, and has been since launch — DSM is the most polished OS in this space, ECC RAM support is unusual at this price, and the platform handles continuous backups, media serving, and a few virtual machines without breaking a sweat. The two main limitations — gigabit-only stock networking and no native hardware transcoding — push power users to the QNAP TS-464. Everyone else gets the easier path with the Synology.

Strengths
  • AMD Ryzen R1600 dual-core CPU with ECC memory support — rare protection against silent data corruption
  • DSM (DiskStation Manager) is the most polished NAS operating system available
  • Two M.2 NVMe slots for read/write caching (or storage pools on DSM 7.2+)
Watch-outs
  • Ships with only 2x 1 GbE ports — 2.5 GbE is becoming standard at this price tier
  • Synology's drive-compatibility list pushes you toward their branded HAT3300 drives
  • Hardware video transcoding requires a Plex Pass workaround — no iGPU like QNAP

The DXP4800 Plus is UGREEN's challenger to Synology and QNAP — 10 GbE stock, modern Pentium Gold 5-core CPU, built-in OS SSD, and 8 GB DDR5 RAM are unusual at this price tier. The hardware is genuinely competitive. The trade-off is UGOS Pro, UGREEN's NAS operating system, which is the youngest in this round-up and still catching up to DSM/QTS on app ecosystem and feature depth. Solid pick if hardware spec matters more than software maturity.

Strengths
  • Intel Pentium Gold 8505 5-core CPU with integrated graphics
  • Built-in 128 GB SSD for the OS — no need to consume a drive bay
  • 10 GbE port stock — no upgrade card needed
Watch-outs
  • UGOS Pro is the newest NAS OS in this lineup — feature parity with DSM/QTS not yet there
  • UGREEN's NAS warranty and long-term software support are unproven
  • Plus tier pricing approaches Asustor Lockerstor territory without the same software maturity

How they stack up

Synology DS923+

DSM is materially more polished than QNAP's QTS, Asustor's ADM, UGREEN's UGOS, and TerraMaster's TOS. Loses on raw spec to the QNAP TS-464 (4K transcoding, 2.5 GbE stock), the UGREEN DXP4800 Plus (10 GbE stock), the TerraMaster F4-424 Pro (8-core CPU), and the Asustor Lockerstor 4 Gen3 (5/10 GbE dual). The software gap closes the hardware gap for most non-power-user buyers.

UGREEN NASync DXP4800 Plus

Most modern hardware in this lineup — newer CPU than the Synology DS923+, QNAP TS-464, and TerraMaster F4-424 Pro on launch date. 10 GbE stock undercuts the Asustor Lockerstor 4 Gen3's dual 5/10 GbE setup but at almost half the price. The bet is software: if you're comfortable with a younger OS, this is the most hardware-per-dollar pick.
