1.2.1 RAID 0 Description
RAID 0 provides disk striping across all disk drives in the array. 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
segments, and then stripes the data segments across each drive in the
array. The size of each data segment is determined by the stripe size,
which is 64 Kbytes.
Note: It is possible to create each disk as a single-drive RAID 0
array. However, spanning across single drive RAID 0 arrays
is not supported.
By breaking up a large file into smaller segments, Embedded MegaRAID
Software can use both SAS/SATA drives to read or write the file faster.
This makes RAID 0 ideal for applications that require high bandwidth but
do not require fault tolerance.
Figure 1.1 shows a RAID 0 array with two disk drives.

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; all data lost if any drive fails
