The closer your data storage is, the faster you can access your data
or applications! With its sleek 1U short-depth rackmount design, the TS-433eU
, fits perfectly into tight spaces, making it ideal for flexible installation.
Install the TS-433eU closer to your operations to effortlessly create edge storage
and enjoy intelligent file management, secure backup, and seamless Docker container applications.

Space saving
Flexible installation for installation in small media cabinets or wall-mounted network racks.

Powerful yet energy efficient
The quad-core ARM Cortex-A55 processor with 4 GB of RAM consumes up to 80% less energy than a similar x86-based NAS.

AI image recognition with NPU acceleration
The built-in NPU enhances AI-powered face recognition
and speeds up subject identification in QNAP’s QuMagie smart album.

Dual 2.5 GbE as standard
Achieve faster data transfer and backup speeds
by enabling port bonding or multi-channel SMB.

Easy storage expansion via USB
Connect the QNAP short-depth USB JBOD TR-004U to the TS-433eU to support up to 144TB of capacity (using 24 TB hard drives in RAID 5).

Backup and snapshot protection for peace of mind
Centralize all your data backups on the TS-433eU and create regular snapshots
to protect your data from ransomware threats.

*NPU is optimized for:

Face, object, and scene recognition (e.g., in applications such as QNAP QuMagie for photo classification).

Real-time image and video analysis.

Acceleration of AI algorithms that would otherwise place a heavy load on the CPU (central processing unit) or GPU (graphics processing unit).

Advantages of NPUs:
Faster processing of AI tasks
Lower power consumption than GPUs
Reduced CPU load, which improves overall system performance
