A technician is configuring a desktop RAID to allow for the best I/O performance and the most storage capacity possible. Which of the following RAID types should the technician use?

The correct answer is A. 0. RAID 0 (striping) writes data across all drives simultaneously, delivering the highest read/write performance. It also uses 100% of the combined disk capacity since there is no parity or mirroring overhead. The trade-off is zero fault tolerance - if one drive fails, all data is l

Explanation

RAID 0 (striping) writes data across all drives simultaneously, delivering the highest read/write performance. It also uses 100% of the combined disk capacity since there is no parity or mirroring overhead. The trade-off is zero fault tolerance - if one drive fails, all data is lost. RAID 5 (B) loses one disk's worth of space to parity. RAID 6 (C) loses two disks' worth. RAID 10 (D) mirrors half the drives, cutting usable capacity in half. For maximum performance and capacity (without concern for redundancy), RAID 0 wins.
