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 les.
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 oers 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 oers high bandwidth.
By breaking up a large le into smaller segments, the RAID controller can use both SAS drives and SATA
drives to read or write the le 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 gure 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.
