With up to 4 disk drives, you have the following options for conguring storage volumes:

video recordings to one or more single disk volumes in a consecutive order.

2. RAID0: A RAID0 volume spreads data blocks of each le across multiple disk drives. The
volume provides no redundancy. RAID0 provides high performance by simultaneously reading
or writing to disk drives, but if a drive fails, all data within is lost. Select at least 2 disks to build
a RAID0 volume.
