4-Bay Short-Depth Rackmount NAS
QNAP TS-464eU-8G Short-Depth NAS
A four-bay short-depth 1U NAS with an Intel Celeron N5095 quad-core processor, 8 GB DDR4 memory, dual 2.5GbE and two built-in M.2 NVMe slots.
Short-depth rack storage for space-conscious installations
The QNAP TS-464eU-8G fits four SATA bays, two M.2 NVMe slots, dual 2.5GbE and HDMI 1.4b into a 292.1 mm-deep 1U chassis. Its compact rack design suits smaller cabinets and cable-dense locations, while Qtier, SSD caching, backup, data recovery and hybrid-cloud applications support everyday storage and protection workflows.
Key features and benefits
292.1 mm short-depth chassis
The reduced chassis depth helps the NAS fit smaller media cabinets and space-limited rack installations.
Two M.2 NVMe slots
Two M.2 2280 PCIe Gen 3 x1 slots support compatible NVMe SSDs for Qtier and SSD caching.
Dual 2.5GbE ports
Two multi-gigabit RJ45 connections support faster team access and port trunking.
HDMI output
HDMI 1.4b supports the listed 4K media playback and real-time transcoding use.
High-speed USB
Two USB 3.2 Gen 2 Type-A ports support 10Gbps USB transfers.
QTS and QuTS hero path
The NAS runs QTS by default and supports switching to QuTS hero from QTS 5.2.2.
Who is this model best for?
A strong choice for
- Small-rack and media-cabinet installations
- Business backup and shared storage
- Teams using 2.5GbE networking
- SSD caching and Qtier
- Direct HDMI-connected display use
Consider another model if you need
- You need PCIe card expansion
