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.)
- Upgrade your network to 10GbE with QNAP's fast and affordable 10GbE Switch
QNAP 10GbE/NBASE-T unmanaged switches allow you to instantly upgrade your network environment at a cost-effective price. With a 10GbE network you can enjoy blazing-fast transfer speeds, empower bandwidth-demanding tasks like virtualization, and enable simultaneous real-time access to large NAS-based files using multiple workstations (ideal for video editing and multimedia). QNAP also provides a 10GbE PCIe network expansion card for the TS-251B and Windows /Linux PCs to take advantage of high-speed LAN environments.
- Real-time 4K video transcoding
Featuring advanced Intel HD Graphics, the TS-251B supports dual-channel 4K H.264 hardware decoding and real-time transcoding, allowing you to convert videos to universal file formats that can be smoothly played across various devices . You can also watch high-quality 4K@30FPS media files on a HDTV using the HDMI output or use with Plex Media Server to stream media files to mobiles devices and media streaming devices (including DLNA, Roku, Apple TV, Amazon Fire TV and Chromecast). The QNAP RM-IR004 remote control (sold separately) can be configured using QButton to customize the actions of individual buttons, providing a more convenient NAS experience.
- Protect important data with snapshots
Snapshots help protect your data by fully recording the NAS system state and metadata. If files are accidentally deleted or modified or the system is afflicted by ransomware, you can use snapshots to quickly restore files to a previously-recorded state. QNAP snapshots are block-based and only record the changed data. Not only does this save storage space but also reduces the time required to back up and restore data. The TS-251B supports up to 1,024 snapshots per NAS and up to 256 snapshots per volume or LUN.
