First home/SOHO Intel dual-core NAS with a PCIe slot for extending NAS functionality

The TS-251B combines secure data storage and multimedia entertainment into one device. Featuring a PCIe slot, the TS-251B is QNAP’s first home/SOHO NAS that allows you to flexibly extend its functionality and potential applications. You can install a QNAP QM2 card to provide M.2 SSD caching/10GbE connectivity and use with Qtier auto-tiering storage to enhance overall system performance; or install a wireless network card (such as the QNAP QWA-AC2600) to turn the TS-251B into a wireless access point and to wirelessly stream your multimedia throughout your home. The TS-251B supports dual-channel H.264 hardware decoding and transcoding, allowing you to enjoy watching NAS media files smoothly across various devices.

  • The PCIe port supports installing a 10GbE network card, a QM2 dual-port M.2 SSD/10GbE card, a USB 3.1 Gen 2 (10Gbps) card, or a wireless network card.

  • 4K media playback and online transcoding; cross-device multimedia viewing via HDMI output or streaming applications.

  • Snapshots fully record the system status and data. If files are accidentally deleted or modified, you can quickly restore the previously-recorded data.

  • Hybrid Backup Sync consolidates backup and sync tasks into a single app, providing multiple layers of data protection.

  • Remotely access the apps and files on your TS-251B via myQNAPcloud and easily manage and share files.

  • Supports containerized applications and hosting virtual machines with various operating systems.
