A technician wants to employ RAID to store a large amount of data and has a large number of drives available. Which of the following RAID levels should the technician utilize to achieve maximum…

RAID 0 is pure striping with no redundancy, so a single drive failure causes total data loss.

RAID 1 only mirrors data between two drives, does not scale to a large number of drives, and wastes 50% of raw capacity.

RAID 5 can only tolerate a single drive failure and carries a significant risk of data loss during array rebuilds when additional errors occur, making it less fault tolerant than RAID 10 across many drives.

RAID 10 (1+0) stripes data across mirrored pairs, meaning it can tolerate multiple simultaneous drive failures as long as no single mirrored pair loses both drives. With a large number of drives, RAID 10 scales well and provides a higher level of fault tolerance than RAID 5, which can only survive a single drive failure before the array is at risk. This combination of redundancy and scalability makes RAID 10 the preferred choice when both fault tolerance and usable capacity across many drives are required.
