Appendix C : RAID
107
RAID 0
RAID 0 provides disk striping across all hard disk drives in the volume. RAID 0 does not
provide any data redundancy, but does offer the best performance of any RAID level.
RAID 0 breaks up data into smaller blocks and then writes a block to each hard disk drive
in the volume. The size of each block is determined by the stripe size parameter, set
during the creation of the RAID set. RAID 0 offers high bandwidth.
By breaking up a large file into smaller blocks, StorTrends NAS Software can use
multiple IDE/SCSI channels and hard disk drives to read or write to the file faster. RAID
0 involves no parity calculations to complicate the write operation. This makes RAID 0
ideal for applications that require high bandwidth but do not require fault tolerance.
Point Description
uses RAID 0 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. All data lost if any hard disk drive fails.
