Q

This is also called striping. It uses two or more disks and improves the disk subsystem
performance, but it does not provide fault tolerance.

Q

This is also called striping with parity. It uses three or more disks with the equivalent of one disk holding parity information. If any single disk fails, the RAID array will
continue to operate, though it will be slower.

Q

_______ is configured as
two or more mirrors configured in a striped configuration. It uses at least four disks but can support more as long as an even number of disks are added. It will continue to operate even if multiple disks fail, as long as at least one drive in each mirror
continues to function.

Q

This is also called mirroring. It uses two disks, which both hold the same data.
If one disk fails, the other disk includes the data so a system can continue to operate after
a single disk fails.
