Chapter 3 RAID Levels

RAID 0

RAID 0 provides disk striping across all drives in the
RAID subsystem. 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 drive in the array. 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,
ADAC Ultra2 S466 can use several drives to read or write
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.

Uses

RAID 0 provides high data throughput, especially for large
files. Any environment hat 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 drive
fails.
