QNAP TS-433EU 4-Bay Short Depth Rackmount NAS, 4 Core 2GHz CPU, 4GM RAM

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

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

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

Dual 2.5GbE as standard
Attain faster data transfer and backup speeds by enabling Port Trunking or SMB Multichannel.

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

Backup and snapshot protection for peace of mind
Centralize all data backups to TS-433eU and regularly create snapshots to safeguard your data against ransomware threats.

The TS-433eU has a shorter chassis depth of only 11.51 inches (292.3mm), making it easy to install in various space-limited environments, including factories, small offices, audiovisual rooms, or surveillance rooms, offering flexibility and maximized space utilization.

2.5GbE as standard for enhanced performance
In modern business IT, a NAS with only 1GbE is a performance bottleneck. The TS-433eU comes with 2.5GbE connectivity as standard, enabling businesses to facilitate bandwidth-demanding applications, such as large file access, backup/restore, and container applications.

Built-in 2.5GbE
The TS-433eU comes with two 2.5GbE ports, outperforming similar competitor NAS that only provides 1GbE.

Enhance overall bandwidth
Obtain increased network speed and fault tolerance by configuring Port Trunking or SMB Multichannel.

NPU accelerates on-device AI performance. 6x faster face recognition
NPU (Neural-network Processing Unit), designed to speed up AI tasks, not only accelerates organization and classification in QuMagie smart album, but also reduces CPU workloads when fulfilling AI-driven requests. When uploading a large number of photos to the TS-433eU, you will enjoy high-speed AI performance of photo processing brought by NPU.

Real-time sync for seamless team collaboration
Whether you're in the office or on the go, you can access the latest files synchronized to TS-433eU on multiple devices for efficient teamwork. Version Control keeps track of document changes, simplifying file management and restoration.

Cross-Device Sync
Sync NAS files across multiple devices, including desktops, laptops, tablets, and phones.

Custom Sync Rules
Set rules for automatic file sync and conflict resolution.

Team Folders
Share folders with specific teams for collaborative file management.

Secure data access at your fingertips
Access NAS data like from a local folder
Map your TS-433eU NAS folders as network drives on your computer, and access files like 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 across Windows®, macOS® and Linux® computers, without compatibility concerns.

Secure remote access
Use QVPN to create a secure virtual private network to access to the TS-433eU. Businesses can further leverage QuWAN to swiftly set up Mesh VPNs, allowing employees to easily join VPN and systems on intranet.
