Which of the following BEST describes RAID 0?
The correct answer is D. Striping. RAID 0 is a RAID level that distributes data across multiple disks in blocks, a technique known as striping, to enhance performance. It does not provide any data redundancy or fault tolerance.

Why each option
RAID 0 is a RAID level that distributes data across multiple disks in blocks, a technique known as striping, to enhance performance. It does not provide any data redundancy or fault tolerance.
Striping with parity describes RAID 5 or RAID 6, which include fault tolerance through parity, unlike RAID 0.
Striping with mirroring describes RAID 10 (or RAID 0+1), a nested RAID level that combines both techniques for performance and redundancy.
Mirroring describes RAID 1, where data is duplicated for redundancy, which is not the function of RAID 0.
RAID 0 employs striping, where data is broken into blocks and written sequentially across multiple disks in a parallel fashion. This significantly improves both read and write performance, but it offers no fault tolerance, as the failure of any single disk results in the loss of all data in the array.
