Quicklinx: D7Z9WS00 Mfr#: TS-253B-4G
  • Celeron


The TS-253 is a powerful, reliable, secure and scalable NAS solution, designed for mission-critical business applications and to meet fast growing data storage needs. The TS-253 supports SATA drives and delivers high performance with persistent throughput, providing a comprehensive storage solution for SMBs to build a reliable private cloud.

  • High performance

    Powered by excellent processor with energy-efficient memory, coupled with the support of SATA, 2 Gigabit LAN ports and HDMI output, the TS-253 is a powerful NAS, that delivers fast read and write speeds. The TS-253 can also automatically increase the processor's clock rate when needed for CPU-intensive tasks. The TS-253's fast encryption and decryption performance provides high transfer speeds with AES 256-bit volume encryption, boosting system performance and security, while ensuring the safety of sensitive business data, stored in the TS-253. When installed with the Wi-Fi network card, the TS-253 can offer remarkably high speeds for transferring large amount of files and streaming bandwidth-consuming multimedia.
  • Comprehensive security solutions

    In open-network environments, business data may be exposed in a potential hack. The TS-253 provides numerous security solutions, such as encrypted access, IP blocking, and more. IT administrators can also control the access rights of each user to different folders, preventing unauthorized access to important files. The TS-253 is validated with military-level AES 256-bit encryption, preventing sensitive business data from unauthorized access and breach, even if the hard drives or the entire system were stolen.
  • Real-time and offline HD video transcoding

    The TS-253 delivers superior real-time Full HD video transcoding to convert videos to formats, that can be smoothly played on PCs, mobile devices and Smart TVs. It allows for a few devices to simultaneously view different videos, stored on the TS-253, with on-the-fly hardware accelerated transcoding. The TS-253 allows you to enjoy instant videos on multiple devices - even those, that lack computing power or have limited file format support - without the need for complicated and time-consuming file conversion. With the benefit of offline transcoding, if you can only connect to an Internet connection with limited/restricted bandwidth, you can still enjoy smooth videos by selecting a pre-rendered lower resolution to play the videos without affecting the TS-253's system performance running other applications. This also allows more people to play videos via streaming. The TS-253 also allows you to set a dedicated folder for automatic video transcoding.
