QNAP TS-251A / NAS server / 2 bays / SATA 6Gb/s / RAID 0, 1, JBOD / RAM 4 GB / Gigabit Ethernet / iSCSI | TS-251A-4G
Description With the growing popularity of smartphones and cameras, a staggering amount of digital media is being created and downloaded every day. This media is also becoming increasingly larger in size, with Full HD movies available to download for mobile devices and 4K on the horizon for HDTVs and download services. This rise in file size makes it impossible for limited mobile devices to store large amounts of media, and also forces users to sacrifice quality for storage space. With the improved TS, QNAP offers customers a NAS with a large and scalable storage solution with a powerful processor and HDMI connectivity for home entertainment and QNAP's unique accelerated transcoding, that allows mobile devices to enjoy media with optimized resolutions and saving their local storage space. The TS also features QNAP's exclusive QvPC technology, that allows you to use a TS model as a PC by simply plugging in a keyboard, mouse and HDMI monitor - greatly extending its functionality and providing even more value for home users.
