TS-433eU: 1U shallow NAS with NPU acceleration
The QNAP TS-433eU is a 1U shallow rack private cloud solution that provides local storage and enhanced security to reduce dependency on external networks. The TS-433eU is equipped with a Neural Processing Unit (NPU) to enhance the facial and object recognition capabilities of QNAP QuMagie.

Highlights
- Flexible deployment for installation in small media cabinets or wall-mounted network racks.
- Powerful and energy-efficient: The quad-core ARM Cortex-A55 processor with 4GB RAM consumes up to 80% less energy than similar NAS devices based on x86 architecture.
- AI Image Recognition with NPU Acceleration: The built-in NPU enhances AI-powered facial recognition and speeds up subject identification in QNAP's QuMagie smart album.
- Dual 2.5 GbE LAN: Get faster data transfer and backup speeds by enabling port aggregation or Multichannel SMB.
- Backup and snapshot protection for peace of mind: Centralise all data backups on TS-433eU and create regular snapshots to protect your data from threats.
Improved AI performance
The NPU (Neural Processing Unit), designed to accelerate AI tasks, speeds up organisation and classification in the QuMagie smart album, as well as CPU workloads when executing AI-based queries. When you transfer a large number of photos to the TS-433eU, you'll benefit from photo processing performance provided by the NPU.


Easy data access
- Map the folders on your TS-433eU NAS as network drives on your computer and access files as if they were stored locally.
- Cross-platform File Sharing: Supporting SMB/CIFS, AFP, WebDAV and NFS protocols, the TS-433eU enables seamless file sharing and transfer between Windows, macOS and Linux computers without compatibility issues.
