Windows Volume Types Comparison
 For the pursuit of data redundancy, which can still recover all the recordings after one disk
fails, it is suggested that you make a Mirrored Volume out of two disks of large capacity.
 If there are quite a few high-megapixel live channels in your system, with one or more clients
frequently accessing Live View and Playback, you may consider making a Striped Volume
that provides the maximum possible capacity with high performance but no failure tolerance.
The table below is based on the available configurations of GNR.

N = the number of disks
V= the disk capacity (V
min
= the capacity of the disk with the smallest storage in the array)
(*)This result is obtained based on the assumption that the disks are of the same capacity.
