4-Bay Short-Depth Rackmount NAS
QNAP TS-464eU-4G Short-Depth NAS
A four-bay short-depth 1U NAS with an Intel Celeron N5095 quad-core processor, dual 2.5GbE, two built-in M.2 NVMe slots and HDMI output.
Compact 1U storage with NVMe caching options
The QNAP TS-464eU-4G places four SATA bays, dual 2.5GbE, two M.2 NVMe slots and HDMI 1.4b in a short-depth 292.1 mm rack chassis. It is designed for business file storage, backup, data recovery and hybrid-cloud workflows where rack depth is limited, while the built-in M.2 slots provide a direct path to compatible SSD caching and Qtier.
Key features and benefits
Short-depth 1U design
The 292.1 mm chassis is designed for smaller media cabinets and rack spaces with substantial cabling.
Built-in M.2 NVMe slots
Two M.2 2280 PCIe Gen 3 x1 slots support compatible NVMe SSDs for Qtier and caching.
Dual 2.5GbE networking
Two RJ45 ports support multi-gigabit access and port trunking.
Intel UHD Graphics
Integrated graphics supports the listed hardware-accelerated transcoding capability.
HDMI 1.4b output
A built-in HDMI connection supports direct display and the stated 4K playback use.
Backup and hybrid cloud
The product positioning includes endpoint backup, data recovery and cloud-storage gateway use.
Who is this model best for?
A strong choice for
- Space-limited rack installations
- Four-bay shared business storage
- Backup and data-recovery workflows
- Teams adopting 2.5GbE
- NVMe caching without a PCIe adapter
