RAID 0
RAID 0 links each drive in the array as one huge drive. Storage capacity is determined by the
smallest drive in the array. That capacity is then applied to format all other drives in the array.
If using a 40 GB, 60 GB, and 50 GB drive in a RAID 0 array, your system will see one huge
drive of 120 GB (40 GB×3).
RAID 0 offers double or more performance under sustained data transfers when one drive per
ATA port is used. In such a configuration, unlike SCSI, ATA drives are always available to the
system. SCSI requires more management of the SCSI bus.
RAID 0: Striped disk array without fault tolerance
Characteristics: Recommended
use:
RAID 0 implements a striped disk array, the data
is broken down into blocks and each block is
written to a separate disk drive.
I/O performance is greatly improved by spreading
the I/O load across many channels and drives.
Fastest and most efficient array type but offers no
fault-tolerance.
Storage capacity = (No. of disks) × (capacity of
smallest disk)
