Instead of going with a Toshiba or Seagate branded HDD as we have seen with the previous models, this time Silicon Power has included a Western Digital WDC WD20NPVZ-00WFZT0 (WD Blue Mobile) drive, which features an 8MB cache and a 5400 rotational speed. This particular model does feature NoTouch Ramp Load Technology, so the recording head never touches the disk media, ensuring less wear to the recording head but also better protection during transit. Additionally, Silicon Power has included a slim and elegant chassis with it that is IPX4 waterproof and scratch resistant thanks to the rhombus surface pattern on the top cover; on the top we do also have a LED included which signals the transfer mode along with the power status.
