Answer : A, C, D

A: Triple parity RAID, wide stripes. RAID in which each stripe has three disks for parity. This is the highest capacity option apart from Striped Data. Resilvering data after one or more drive failures can take significantly longer due to the wide stripes and low random I/O performance.

C: Double parity RAID is a higher capacity option than the mirroring options and is intended either for high-throughput sequential-access workloads (such as backup) or for storing large amounts of data with low random-read component.

D: RAID0 does not provide redundancy.
