RAID allows multiple disks to be connected in an array. A RAID array allows extra
capabilities like increased speed and performance, or increased data protection and
security. A RAID array is viewed as a single disk by the computer and the operating
system. Details of the different RAID levels are outlined in the sections below.
WARNING!
Irrecoverable data loss occurs if a working drive is removed when
trying to remove a failed drive. It is strongly recommended to mark the
physical connections of all SATA disk drives. Drive locations can be
identified by attaching stickers to the drive bays. If a drive member of a
RAID array should fail, the failed drive can then be correctly identified.
NOTE:
A configured RAID volume (which may consist of multiple hard drives)
appears to an operating system as a contingent storage space. The
operating system will not be able to distinguish the physical disk drives
contained in a RAID configuration.
