QNAP Ts-251a

Product details

The TS-251A features the innovative USB 3.0 QuickAccess port, which allows you to complete the initial installation of the NAS in no time and then directly access the files and data stored on the NAS. It also supports two additional transmission modes: Ethernet NAS mode and block-based iSCSI SAN mode.

The combination of USB QuickAccess, NAS and iSCSI SAN in a single device makes the TS-251A a powerful yet user-friendly storage solution - ideal for backup, synchronization, remote access and entertainment. The TS-251A is powered by an upgradeable, high-performance 14nm Intel® Celeron® N3060 dual-core 1.6GHz processor, supporting 4K video playback and transcoding.

With the mixture of high speed, sophisticated protection for the stored data and more connections, the TS-251A secured second place. This makes it possible to get over the sometimes somewhat awkward operation. Unusual for a NAS: The Qnap can be connected directly to TVs (HDMI) and PCs (via USB).
