#1 · Top Pick
Best for: Plex media-server and home-lab users who want strong hardware transcoding and stock 2.5GbE at a reasonable price.
QNAP TS-464
2 sources$639as of Oct 16
▾Why it's ranked here

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
  • — Two M.2 NVMe slots plus a PCIe Gen 3 expansion slot
Watch-outs
  • — Past QNAP security advisories make hardening important

#2
Best for: Media-server and VM users who want maximum CPU power in a 4-bay and can tolerate less mature software.
TerraMaster F4-424 Pro
3 sources$730.99as of Oct 11
▾Why it's ranked here

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
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

Asustor Lockerstor 4 Gen3 (AS6804T)
#3
★ Premium Pick
Best for: Power users and creative pros who need maximum throughput, multi-10GbE networking and an all-flash pool in a 4-bay.
Asustor Lockerstor 4 Gen3 (AS6804T)
3 sources$1,517.99as of Oct 11
▾Why it's ranked here

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
  • — 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
  • — Total cost climbs fast once you add drives and SSDs
  • — Overkill for typical home file-storage and backup needs

Synology DS923+
#4
Best for: Home and small-office users who prioritize the most polished, reliable NAS software and a deep app ecosystem over raw hardware specs.
Synology DS923+
2 sources
▾Why it's ranked here

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
  • — 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

#5
Best for: Value-focused home and prosumer users who already have 10GbE networking and want maximum hardware for the money.
UGREEN NASync DXP4800 Plus
2 sources$656.99as of Oct 11
▾Why it's ranked here

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
Watch-outs
  • — UGOS software is less mature than Synology DSM or QNAP QTS
  • — Newer vendor with a shorter track record in NAS
