5 Select a RAID Level from the drop-down list. This can be

either:

• RAID 0 - RAID 0 is a striped disk array without fault

tolerance. Provides data striping (spreading out blocks of

each file across multiple disk drives) but no redundancy.

This improves performance but does not deliver fault

tolerance. If one drive fails then all data in the array is lost

• RAID 1 - RAID 1 provides disk mirroring. Level 1 provides

twice the read transaction rate of single disks and the

same write transaction rate as single disks

• RAID 5 - RAID 5 provides data striping at the byte level

and also stripe error correction information. This results in

excellent performance and good fault tolerance. Level 5 is

one of the most popular implementations of RAID.

6 Select a Chunk Size (KB) from the drop-down list. This is the

size of the data chunks written to each disk.

7 Select the disks you wish to be members of the RAID from the

Disks available for new RAID list. The new RAID will

allocate all available storage space on those disks to the RAID.

8 Click to add the new RAID.
