TerraMaster F4-424 Pro 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

UGREEN NASync DXP4800 Plus comes out ahead by a narrow margin (4.2 vs 4.3). The gap is mostly about buyers who want stock 10 GbE and modern hardware without paying the Asustor Lockerstor Gen3 premium — read the strengths below before deciding.

Ranked #4 in Best 4-Bay NAS Drives

TerraMaster F4-424 Pro

4.2

$700

The F4-424 Pro is the value-per-spec pick — 8-core CPU and 32 GB DDR5 RAM at $500 is unmatched. The catch is TOS, which most enthusiasts swap out for TrueNAS Scale or Unraid. If you were going to do that anyway, this is the platform; if you want a polished out-of-box experience, the Synology DS923+ or QNAP TS-464 are better matches.

Strengths

— Core i3-N305 8-core/8-thread CPU is the highest core count in this round-up
— 32 GB DDR5 RAM stock — far more than the DS923+ or TS-464 ship with
— Dual 2.5 GbE ports stock

Watch-outs

— TOS (TerraMaster Operating System) is the least polished NAS OS in this lineup
— Build quality is plastic where Asustor and Synology use metal
— TerraMaster's reputation for support and patches is mixed

Higher ratedRanked #3 in Best 4-Bay NAS Drives

UGREEN NASync DXP4800 Plus

4.3

$700

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

TerraMaster F4-424 Pro

Highest core count and most stock RAM of any pick here. Less polished software than the Synology DS923+, QNAP TS-464, and Asustor Lockerstor 4 Gen3 — most users end up running TrueNAS or Unraid. The UGREEN DXP4800 Plus runs similar new-OS-young-platform energy but ships with proper UGREEN OS rather than an excuse to wipe and reinstall.

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.
