The short answer

Synology DS923+ comes out ahead by a narrow margin (4.3 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.

Ranked #4 in Best 4-Bay NAS Drives
Asustor Lockerstor 4 Gen3 (AS6804T)
$1,319.99as of Jun 7

The Asustor Lockerstor 4 Gen3 (AS6804T) is the no-compromise power-user pick, with an AMD Ryzen V3C14, ECC DDR5, dual 10GbE plus dual 5GbE, USB4, and four M.2 slots. TechRadar measured 3.1–3.5 GB/s using both 10GbE ports and USB4 together. The catch is the $1,299 diskless price, which TechRadar called a tough pill when capable 4-bays cost around $800 less.

Strengths
  • — AMD Ryzen V3C14 with ECC DDR5 is the most powerful CPU here
  • — Dual 10GbE plus dual 5GbE ports for up to 30GbE of bandwidth
  • — Two USB4 Type-C ports at up to 40Gbps for Thunderbolt storage
Watch-outs
  • — At $1,299 diskless, it is more than twice the price of midrange rivals
  • — Total cost climbs fast once you add drives and SSDs
  • — Overkill for typical home file-storage and backup needs

Synology DS923+
Higher ratedRanked #1 in Best 4-Bay NAS Drives
Synology DS923+
$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

Asustor Lockerstor 4 Gen3 (AS6804T)

The Lockerstor 4 Gen3 is the performance king, with a stronger CPU and far more networking (dual 10GbE + dual 5GbE) than the UGREEN NASync DXP4800 Plus, Synology DS923+, QNAP TS-464 or TerraMaster F4-424 Pro. Its price is also more than double theirs, so it only makes sense when you genuinely need the throughput.

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.
