A technician is implementing a RAID 10 array on a server.
Which of the following is the MINIMUM number of disks needed for this array?

A. B. C. D.C.
RAID 10 is a combination of RAID 1 (mirroring) and RAID 0 (striping). It requires a minimum of four disks to implement.
In RAID 1, data is written identically to two or more disks, which creates a mirrored set of disks. This provides redundancy, as the data can still be accessed if one disk fails.
In RAID 0, data is striped across multiple disks, which improves performance by allowing multiple disks to read and write data simultaneously.
In RAID 10, the disks are divided into mirrored sets, and then those sets are striped together. This provides both redundancy and performance benefits.
To implement RAID 10, a minimum of four disks are needed because it requires at least two pairs of mirrored disks to be striped together.
Therefore, the correct answer to the question is C. Four.
