    (page 99) Introduction to RAID RAID (Redundant Array of Independent Disks) allows multiple disk drives to be combined together in a logical drive. The operating system sees the logical drive as a single storage device, and treats it as such. The RAID software and/or controller handle all of the

    WebPAM User Manual RAID 0 - Stripe When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple disk drives. Performance is increased, since the workload is balanced between drives or "members" that form the logical drive. Identical drives are

    the workload is distributed in the most efficient manner. Whichever drive is not busy and is positioned closer to the data will be accessed first. With RAID 1, if one disk drive fails or has errors, the other mirrored disk drive continues to function. This is called Fault Tolerance. Moreover, if

    Expansion There are limitations to how large you can expand a logical drive, depending on the size of your current logical drive. The current PC Operating Systems support a 10-byte LBA format. This means that a logical drive can have up to 4 billion address blocks or sectors. Multiply the number
