Asustor Lockerstor 4 Gen3 (AS6804T) vs QNAP TS-464

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

QNAP TS-464 comes out ahead by a narrow margin (4.4 vs 4.5). The gap is mostly about Plex/Jellyfin households running multiple 4K HEVC streams who want hardware transcoding built in — read the strengths below before deciding.

$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

The TS-464 is the right answer if Plex transcoding is the primary use case. The Celeron N5095's iGPU handles four simultaneous 4K HEVC transcodes without choking, and the dual 2.5 GbE ports plus a PCIe slot for 10 GbE expansion give you more network headroom than the Synology DS923+. The trade-off is QTS — functional but less refined than DSM. Power users learn to live with it; casual users may not.

Strengths
  • Intel Celeron N5095 with iGPU — sustained 4K HEVC hardware transcoding for Plex/Jellyfin
  • Dual 2.5 GbE ports stock, port trunking gets close to 10 GbE speeds (~589 MB/s)
  • PCIe Gen 3 slot lets you add a 10 GbE card later
Watch-outs
  • QTS is less polished than Synology's DSM — more menus, less consistent UI
  • QNAP has shipped security vulnerabilities that received late patches in the past
  • Higher idle power than the Synology DS923+

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.

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.
