Compact edge storage for tight spaces
The 1U chassis is 292.3mm deep and is designed for small media cabinets, wall-mounted network racks and other locations where a conventional rackmount server may not fit.
- Four hot-swappable SATA bays support 3.5-inch hard drives and 2.5-inch solid state drives.
- The supplied deployment examples include factories, small offices, audiovisual rooms and surveillance rooms.
- Three 40mm cooling fans are specified.
ARM processing, onboard memory and NPU acceleration
A 64-bit ARM Cortex-A55 quad-core 2.0GHz processor, 4GB onboard memory and hardware-accelerated encryption support everyday backup and application workloads.
- The 4GB memory is non-expandable, and some RAM is reserved for shared graphics memory.
- The built-in NPU accelerates image recognition and subject identification in QNAP QuMagie.
- The supplied information reports face recognition up to six times faster while reducing CPU workload.
Dual 2.5GbE networking and supplied throughput
Two 2.5GbE ports support file access, backup, restore and container application traffic. Port Trunking or SMB Multichannel can increase available bandwidth and connection resilience.

The figures were measured in QNAP laboratories with the stated TS-433eU test environment and may vary.
Backup, snapshots and supplied expansion example
The supplied information lists centralised backup, regular snapshots and Docker container applications. A QNAP short-depth USB JBOD TR-004U is identified as an expansion option.
- The supplied example supports up to 144TB using 24TB hard drives in RAID 5.
- Two USB 3.2 Gen 1 ports are included.
- Wake on LAN and Jumbo Frame support are listed.
Important deployment and capacity notes
- The supplied source does not state whether drives are included, so no diskless claim has been added.
- The 4GB onboard memory is non-expandable.
- The 144TB figure is a supplied example using a TR-004U, 24TB hard drives and RAID 5.
- Performance and NPU acceleration figures were measured or stated under supplied conditions and may vary.
