QNAP TS-464 vs Synology DS923+

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 (4.4 vs 4.6). The gap is mostly about Home and small-office users who prioritize the most polished, reliable NAS software and a deep app ecosystem over raw hardware specs. — read the strengths below before deciding.

The QNAP TS-464 is the Plex-and-transcoding sweet spot, pairing an Intel Celeron N5095 with dual 2.5GbE ports, two M.2 NVMe slots and a PCIe expansion slot. StorageReview called it great value for SMBs and home users at its base price and praised its HEVC transcoding. The 4GB base RAM is the main pinch point, and QTS, while deep, is busier than the competition's software.

Strengths
  • Dual 2.5GbE ports out of the box with port trunking to 5Gbps
  • Intel Celeron N5095 handles Plex HEVC/H.265 transcoding well
  • Two M.2 NVMe slots plus a PCIe Gen 3 expansion slot
Watch-outs
  • 4GB base RAM is tight for VMs, surveillance or heavy multitasking
  • QTS interface is powerful but busier than rivals
  • 2.5GbE needs compatible switch gear most homes lack

$639.99as of Jun 7

The Synology DS923+ remains the safe default 4-bay NAS thanks to DSM, the most mature operating system in the category, and a deep app ecosystem. StorageReview measured strong RAID-5 throughput and sustained 1,000+ MB/s once a 10GbE module is added. Its weak spots are dated networking (dual 1GbE stock) and a modest CPU, but for households who want it to just work, it is still the most recommended pick.

Strengths
  • DiskStation Manager (DSM) is the most polished, mature NAS OS available
  • Deep, well-supported app library for backup, sync, photos and surveillance
  • Two built-in M.2 NVMe slots for SSD caching or a storage pool
Watch-outs
  • Ships with only dual 1GbE ports; 2.5GbE rivals beat it out of the box
  • AMD Ryzen R1600 is an older, modest dual-core CPU
  • NVMe storage-pool support is limited to Synology-branded drives

How they stack up

QNAP TS-464

The TS-464 ships with 2.5GbE like the TerraMaster F4-424 Pro, beating the Synology DS923+'s stock 1GbE, but it trails the 10GbE on the UGREEN NASync DXP4800 Plus and Asustor Lockerstor 4 Gen3. Its Celeron handles Plex transcoding better than the Synology's AMD chip but not as strongly as the UGREEN's Pentium.

Synology DS923+

The DS923+ wins on software maturity over the UGREEN NASync DXP4800 Plus and QNAP TS-464, but its stock dual 1GbE networking trails the 2.5GbE on the QNAP and TerraMaster F4-424 Pro and the 10GbE on the UGREEN and Asustor Lockerstor 4 Gen3. Its CPU is older and weaker than every rival here.
