CHAPTER 4: USING YOUR DESKTOP
RAID Level 10
RAID 10, a combination of RAID 1 and RAID 0, uses disk striping across mirrored
disks. It provides high data throughput and complete data redundancy. RAID 10
can support up to eight spans, and up to 32 physical disks per span.
RAID Level 5
RAID level 5 uses data parity. RAID level 5 stripes both data and parity information
across three or more drives. It provides data striping at the byte level and also
stripe error correction information (rotating parity array). is results in excellent
performance and good fault tolerance.
If a drive failure occurs, subsequent read and write operations are directed to the
other surviving drives. A replacement drive can then be rebuilt using the data
from the surviving drives. Since data is duplicated on the primary and additional
drives, four 120-GB drives collectively have a maximum of 360-GB on which to
store data.
