Intel Rapid Storage

The Intel Rapid Storage technology supported allows you to

create a RAID 0 and RAID 1 set using only two identical hard disk

drives. The Intel Rapid Storage technology creates two partitions

on each hard disk drive to create a virtual RAID 0 and RAID 1 sets.

This technology also allows you to change the hard disk drive

partition size without losing any data.

RAID 10

RAID 10 is a striped configuration with RAID 1 segments whose

segments are RAID 1 arrays. This configuration has the same

fault tolerance as RAID 1, and has the same overhead for fault-

tolerance as mirroring alone. RAID 10 achieves high input / output

rates by striping RAID 1 segments. In some instances, a RAID 10

configuration can sustain multiple simultaneous drive failure. A

minimum of four hard disk drives is required for this setup.

RAID 5

RAID 5 stripes both data and parity information across three or

more hard disk drives. Among the advantages of RAID 5

configuration include better HDD performance, fault tolerance,

and higher storage capacity. The RAID 5 configuration is best

suited for transaction processing, relational database applications,

enterprise resource planning, and other business systems. Use a

minimum of three identical hard disk drives for this setup.
