Why use RAID 0

RAID 0 allows you to combine multiple disks into one large disk. Provide much faster read and write as data is read or written on multiple disks same time.

Disadvantages of using RAID 0

If one of the disk in your RAID 0 array fail, all data in your RAID 0 array will be lost.

If your date is important, don't use RAID 0.
