Uses Provides high data throughput, especially for large files.Any environment that does not
require fault tolerance.
Strong points Provides increased data throughput for large files.
No capacity loss penalty for parity.
Weak points Does not provide fault tolerance or high bandwidth.All data is lost if any drive fails.
Drives 1 to 32
RAID 0 Drive Groups
A RAID 0 drive group provides disk striping across all drives in the RAID drive group. A RAID0
drive group does not provide any data redundancy, but the RAID 0 drive group offers the best
performance of any RAID level. The RAID 0 drive group breaks up data into smaller segments,
and then stripes the data segments across each drive in the drive group. The size of each data
segment is determined by the stripe size. A RAID 0 drive group offers high bandwidth.
By breaking up a large file into smaller segments, the RAID controller can use both SAS
drives and SATA drives to read or write the file faster. A RAID 0 drive group involves no parity
calculations to complicate the write operation. This situation makes the RAID 0 drive group ideal
for applications that require high bandwidth but do not require fault tolerance. The following
table provides an overview of the RAID 0 drive group. The following figure provides a graphic
example of a RAID 0 drive group.
NOTE
RAID level 0 is not fault tolerant. If a drive in a RAID 0 drive group fails, the entire virtual drive (all drives
associated with the virtual drive) fails.
