^* Please note that with RAID5, total available capacity = (N*drive)-(1*drive) so if one has a 960GB(3x320GB) RAID5 system, available/usable capacity is 640GB((3*320GB)-(1*320GB)). Read the product specs carefully because unlike many other DVR manufacturers, we clearly list both total and usable capacity of our RAID-equipped DVRs.

^** May require additional accessories. Email or call for details.
