The DS923+ is the default 4-bay NAS recommendation for most users, and has been since launch — DSM is the most polished OS in this space, ECC RAM support is unusual at this price, and the platform handles continuous backups, media serving, and a few virtual machines without breaking a sweat. The two main limitations — gigabit-only stock networking and no native hardware transcoding — push power users to the QNAP TS-464. Everyone else gets the easier path with the Synology.
Strengths
- +AMD Ryzen R1600 dual-core CPU with ECC memory support — rare protection against silent data corruption
- +DSM (DiskStation Manager) is the most polished NAS operating system available
- +Two M.2 NVMe slots for read/write caching (or storage pools on DSM 7.2+)
- +Optional 10 GbE upgrade card unlocks faster network speeds for power users
- +Supports 9-drive expansion via the DX517 expansion unit
Watch-outs
- −Ships with only 2x 1 GbE ports — 2.5 GbE is becoming standard at this price tier
- −Synology's drive-compatibility list pushes you toward their branded HAT3300 drives
- −Hardware video transcoding requires a Plex Pass workaround — no iGPU like QNAP
- −Higher MSRP than the QNAP TS-464 and TerraMaster F4-424 Pro
How it compares
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.
Who this is for
At a glance: households and prosumers who want the least-friction NAS experience and value mature software over raw hardware spec.
