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.

Intel® Celeron® J3355 dual-core processor and AES-NI hardware encryption

Powered by a 14nm Intel® Celeron® J3355 dual-core 2.0GHz processor (burst up to 2.5 GHz), 2GB/4GB DDR3L RAM (up to 8GB), a single Gigabit LAN port, and supporting SATA 6Gb/s hard drives, the TS-251B provides dependable performance of up to 672 MB/s read/write speeds. The TS-251B features Intel® AES-NI hardware-accelerated encryption for both full NAS volumes and shared folders, boosting system performance while ensuring the security of sensitive data stored in the TS-251B.

Extend NAS functionality with the PCIe slot

With a PCIe expansion slot, the TS-251B provides flexibility in extending NAS functionality and potential applications. Install a QNAP QM2 card to provide M.2 SSD caching/10GbE connectivity and use with Qtier tiered storage for optimal system performance; use the TS-251B as a wireless access point by installing a compatible wireless network card (such as the QNAP QWA-AC2600) to create a wireless media streaming environment; or boost the USB connectivity of the TS-251B by installing a USB 3.1 Gen 2 (10Gbps) card.

A tailor-made private wireless network that meets your needs

By installing the QWA-AC2600 and WirelessAP Station app, your NAS will evolve into a high-performance wireless access point that can be connected to from multiple devices. The QWA-AC2600 can also be used to extend your wireless network coverage. Combined with useful features (including DHCP and NAT) provided by the Network and Virtual Switch app, the QWA-AC2600 can be used for a variety of applications, delivering private, fast, low-latency and secure connectivity across your home and/or workplace. (WirelessAP Station requires Container Station to be installed on your QNAP NAS.)
