Introduction
1-4
By striping the drives in the array with stripes large enough so that each record
falls entirely within one stripe, most records can be evenly distributed across all
drives. This keeps all drives in the array busy during heavy load situations. This
situation allows all drives to work concurrently on different I/O operations, and
thus maximize the number of simultaneous I/O operations that can be performed
by the array.
Definition of RAID Levels
RAID 0
is typically defined as a group of striped disk drives without parity or data
redundancy. RAID 0 arrays can be configured with large stripes for multi-user
environments or small stripes for single-user systems that access long sequential
records. RAID 0 arrays deliver the best data storage efficiency and performance
of any array type. The disadvantage is that if one drive in a RAID 0 array fails, the
entire array fails.
