Working with RAID
A redundant array of independent disks (RAID) is a disk storage
configuration that increases performance or data redundancy. There are four
basic RAID levels discussed in this section.
NOTE:
RAID requires multiple hard drives. The number of hard drives required
varies depending on the RAID configuration.
•
RAID level 0 is recommended for higher performance (faster throughput).
•
RAID level 1 is recommended for users who need a high level of data
integrity.
•
RAID level 0+1 is recommended for higher performance and data
integrity
•
RAID level 5 is recommended for higher performance and fault tolerance.

levels (5, 10, 50). For information about these levels, see

RAID Level 0
NOTICE:
RAID level 0 provides no redundancy. Therefore, a failure of one drive
results in the loss of all data. Perform regular backups to protect your data.
