The QNAP TS-433EU in depth

Short-depth 1U chassis

At only 292.3 mm deep, the TS-433eU fits space-limited environments such as factories, small offices, audiovisual rooms and surveillance rooms, maximising rack space. It comes with two 2.5GbE ports as standard to avoid the bottleneck of 1GbE-only NAS.

Efficient ARM with NPU

An energy-efficient Cortex-A55 quad-core CPU and 4GB RAM handle multitasking, AES hardware encryption protects data, and the NPU accelerates AI image recognition in QuMagie. In QNAP's testing it reached 282 MB/s read and 286 MB/s write over 1 x 2.5GbE.

Business backup and security

Backup apps support Rsync, FTP and CIFS/SMB with secondary backup and restore, Qsync keeps teams in sync, and Qsirch adds AI-powered search. QVPN, QuWAN SD-WAN, AD/LDAP integration and Security Center help secure the NAS, and DA Drive Analyzer predicts drive failures.
