Asustor Lockerstor 4 Gen3 (AS6804T) 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

Asustor Lockerstor 4 Gen3 (AS6804T) comes out ahead by a narrow margin (4.4 vs 4.3). The gap is mostly about prosumers, content creators, and small business buyers who need 10 GbE networking, ECC RAM, and four NVMe slots in one box — read the strengths below before deciding.

Asustor Lockerstor 4 Gen3 (AS6804T)
$1,299

The Lockerstor 4 Gen3 is the premium pick — Ryzen V3C14 CPU, ECC DDR5, dual 10 GbE + dual 5 GbE, and four M.2 NVMe slots. It's a different price tier than the rest of this lineup, but if you're building a small-business backup target or a prosumer Plex+everything box, the networking and CPU headroom matter. TechRadar's only real criticism is the price; the hardware is unambiguously top-tier in this segment.

Strengths
  • AMD Ryzen V3C14 quad-core with ECC DDR5 RAM — enterprise-grade memory protection
  • Dual 5 GbE + Dual 10 GbE ports stock — fastest networking in this round-up
  • Four M.2 NVMe slots — most flexible caching/storage tier setup here
Watch-outs
  • $1,299 puts it at 2x the Synology DS923+ price tier
  • ADM still trails DSM and QTS in polish and third-party app catalog
  • Overkill for households or small office use — this is a prosumer/SMB tier
UGREEN NASync DXP4800 Plus
Ranked #3 in Best 4-Bay NAS Drives

$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

Asustor Lockerstor 4 Gen3 (AS6804T)

Most expensive pick here — 2x the Synology DS923+ and TerraMaster F4-424 Pro, but the only one with both 5 GbE and 10 GbE networking. ADM is more capable than UGREEN's UGOS Pro and TerraMaster's TOS but still trails DSM and QTS. The QNAP TS-464's iGPU transcoding is the one feature you give up versus the Lockerstor — its server-grade Ryzen lacks an iGPU.

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.
