Zoom Computers offers WD Hard Drive that is equipped with All Frame technology which works with ATA streaming to reduce frame loss, improve playback and increases the number of drive bays supported. All Frames reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missed frames and lost footage is a critical problem when an event occurs and surveillance footage needs to be retrieved. WD provides the confidence you should expect when it is time to play back and review critical surveillance footage. WD builds hard drives to the demanding requirements for durability, shock tolerance and long-term reliability.
