Asustor Lockerstor 4 Gen3 (AS6804T)

Averaged from + undefined
The verdict

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.

Asustor Lockerstor 4 Gen3 (AS6804T)

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
  • +Aluminum chassis with proper thermal design for sustained heavy loads
  • +ADM (Asustor Data Master) has improved meaningfully across recent versions

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
  • Larger physical chassis than the other picks here

How it compares

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.

Who this is for

At a glance: prosumers, content creators, and small business buyers who need 10 GbE networking, ECC RAM, and four NVMe slots in one box.

Why you’d buy the Asustor Lockerstor 4 Gen3 (AS6804T)

Synology DS923+
#1 · Top Score

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.

QNAP TS-464
#2

QNAP TS-464

Beats the Synology DS923+ on hardware transcoding and stock 2.5 GbE, but loses on operating system polish. Less raw CPU than the TerraMaster F4-424 Pro (which offers 8 cores vs the TS-464's 4), but the Celeron's iGPU is a meaningful advantage for media work. Cheaper than the Asustor Lockerstor 4 Gen3 and UGREEN DXP4800 Plus while still offering credible 2.5 GbE.

UGREEN NASync DXP4800 Plus
#3

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.

TerraMaster F4-424 Pro
#4

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.
