1 6 and 5.
1 is mirroring which adds redundancy by creating a mirrored drive to fall back on.
5 is using a distributed parity saves a block of each disk to create a fall back.
6 is using dual parity to save multiple blocks on each disk for a fall back.
B,C and D
RAID 1 consists of an exact copy of a set of data on two (most common) or more disks. Read performance
and reliability are the main goals. Write performance is not increased because data needs to be mirrored to
all disks. RAID 1 includes fault tolerance, so if one disk fails the other one can keep working since it
contains a complete copy of the data.
• RAID 5 consists of block-level striping with distributed parity. Data and parity are striped across three or
more disks. This RAID level provides better performance than mirroring as well as fault tolerance. It can
withstand the failure of a single drive, as subsequent reads can be calculated from the distributed parity, so
that no data is lost.
RAID 60 combines block-level striping of RAID 0 with the distributed double parity of RAID 6. Write
performance is affected, but the enhanced redundancy provides peace of mind. Dual parity allows the
failure of two disks in each RAID 6 array.
