QNAP TS-464

4.5

3 sources2 derived$639as of Jun 7

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

Watch-outs

— 4GB base RAM is tight for VMs, surveillance or heavy multitasking
— QTS interface is powerful but busier than rivals

Synology DS923+

4.3

3 sources2 derived

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

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

Asustor Lockerstor 4 Gen3 (AS6804T)

4.3

3 sources1 derived$1,517.99as of Aug 1

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

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

TerraMaster F4-424 Pro

4.2

3 sources1 derived$687.99as of Aug 1

The TerraMaster F4-424 Pro is the CPU heavyweight of the media-class 4-bays, built around an 8-core Intel Core i3-N305 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

— Powerful 8-core Intel Core i3-N305 CPU, the strongest media-class chip here
— 32GB DDR5 memory standard for VMs and containers

Watch-outs

— TOS software still feels unpolished next to DSM or QTS
— Poor airflow to CPU and NVMe slots can force heatsink removal

UGREEN NASync DXP4800 Plus

3.9

4 sources2 derived$619.99as of Aug 1

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, which reviewers agree is improving fast but still trails the maturity of Synology and QNAP software.

Strengths

— 10GbE plus 2.5GbE networking included out of the box
— 12th-gen Intel Pentium Gold 8505 5-core CPU is far faster than rivals' chips

Watch-outs

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