Page 43: About Raid Configurations
There are several RAID configurations available in the computer industry for different types of uses. Your Dell Precicion computer supports RAID level 0, RAID level 1, RAID level 5, or RAID level 10, also known as RAID level 1+0. A RAID level 0...
Page 44: Raid Level 0
RAID Level 0 NOTICE: Because a RAID level 0 configuration provides no data redundancy, a failure of one drive results in the loss of all data. To protect your data when using a RAID level 0 configuration, perform regular backups. RAID level 0 uses a storage technique known as data striping to provide a high data access rate.
Page 45: Raid Level 5
