RAID Level “X” (X-RAID)
RAID level “X”, or X-RAID, is similar to RAID level 5, is optimized for large sequential access for
the best possible media streaming performance. The “X” also refers to its natural volume
eXpandability. In X-RAID mode, with one disk, the volume is non-redundant and has the capacity
of the single disk. By adding a 2
nd disk, the capacity remains the same, but the data is now mirrored
between the two disks. With redundancy, your data will not be lost in the event of a disk failure. By
adding a 3
rd disk, the capacity doubles while maintaining redundancy. By adding a 4 th disk, the
capacity triples with redundancy. The process of volume expansion is automatic. When a disk has
been added, you will be notified of the steps being taken, and you will be notified when you will
need to reboot to continue with the expansion process.
