Key specifications at a glance

Choose a storage layout that suits your files

The four drive bays support 2.5-inch and 3.5-inch SATA HDDs or SSDs. RAID options include levels 1, 5, 6 and 10, as well as RAID 0 and JBOD. Online RAID migration and expansion let you adjust a supported RAID setup while the NAS remains online.

Hot-swap bays and RAID rebuild support help with drive maintenance. Choose a RAID level to match your priorities for capacity and drive redundancy.

Make better use of your network

The TS-433 has both a Gigabit Ethernet port and a 2.5GbE port. Connect it to a compatible 2.5GbE network to make use of the faster connection for file sharing and collaboration. It also supports Wake-on-LAN, jumbo frames and iSCSI.

Back up and protect important files

QTS 5 provides backup functions, cloud backup support and snapshots. Snapshots record the system’s state, so you can restore files or settings to an earlier point. The NAS also supports 256-bit AES encryption, HTTPS and SSH.

The built-in NPU accelerates on-device AI features, including face and object recognition. QNAP’s Container Station and App Centre also let you add container applications and other tools.
