The short answer

TerraMaster F4-424 Pro comes out ahead by a clear margin (4.3 vs 3.7). TerraMaster F4-424 Pro is best for: Media-server and VM users who want maximum CPU power in a 4-bay and can tolerate less mature software. Read the strengths below before deciding.

TerraMaster F4-424 Pro
Higher ratedRanked #2 in Best 4-Bay NAS Drives
TerraMaster F4-424 Pro
3 sources$730.99as of Oct 11

The TerraMaster F4-424 Pro is the CPU heavyweight of the media-class 4-bays, built around an 8-core Intel Core i3-N300 with 32GB of DDR5 standard and dual 2.5GbE. Neowin called it the most powerful media-class 4-bay on the market. The trade-offs are TerraMaster's still-maturing TOS software and some build quirks like weak internal airflow and non-locking drive trays.

Strengths
  • — 32GB DDR5 memory standard for VMs and containers
  • — Dual 2.5GbE ports with link aggregation to 5Gbps
  • — Often the cheapest way to get this much CPU in a 4-bay
Watch-outs
  • — TOS software still feels unpolished next to DSM or QTS
  • — Drive trays do not lock, so a drive can be pulled from a running system

UGREEN NASync DXP4800 Plus
Ranked #5 in Best 4-Bay NAS Drives
UGREEN NASync DXP4800 Plus
2 sources$656.99as of Oct 11

The UGREEN NASync DXP4800 Plus is the clearest value proposition in the category, pairing a 12th-gen Intel Pentium Gold 8505 with 10GbE and 2.5GbE networking and 8GB of DDR5 out of the box. ITPro found it among the fastest enclosures it tested on ATTO benchmarks. The catch is UGOS: KitGuru and PetaPixel both found its app catalogue sparse next to what Synology and QNAP offer, and ITPro judged it capable but lacking the depth of Synology's DiskStation Manager.

Strengths
  • — 10GbE plus 2.5GbE networking included out of the box
  • — 8GB DDR5 RAM, expandable to 64GB for VMs and containers
  • — OS preinstalled on a dedicated 128GB SSD, unusual at this price
Watch-outs
  • — UGOS software is less mature than Synology DSM or QNAP QTS
  • — Newer vendor with a shorter track record in NAS
  • — App ecosystem still trails the established players

How they stack up

TerraMaster F4-424 Pro

The F4-424 Pro has the strongest CPU of the 2.5GbE-class units, beating the QNAP TS-464's Celeron and the Synology DS923+'s AMD chip, and matches the QNAP on dual 2.5GbE. But it lacks the 10GbE of the UGREEN NASync DXP4800 Plus and Asustor Lockerstor 4 Gen3, and its TOS software trails all of them on polish.

UGREEN NASync DXP4800 Plus

The DXP4800 Plus is the hardware-value leader, beating the Synology DS923+ and QNAP TS-464 on CPU and including 10GbE that the DS923+ charges extra for. It costs far less than the Asustor Lockerstor 4 Gen3 while offering similar 10GbE, and its DDR5 CPU outclasses the TerraMaster F4-424 Pro's, though its UGOS software is less polished than all of them.
