Which requirement is true for all RAID 10 setups on an HP Z Workstation?

In a RAID 10 configuration, also known as RAID 1+0, the setup requires both mirroring and striping. This means that the data is mirrored across pairs of drives for redundancy (just as in RAID 1), and those mirrored sets are then striped for improved performance (similar to RAID 0).

For RAID 10 to operate correctly, it must consist of an even number of drives, as each drive must be paired with another for the mirroring process. The minimum requirement is four drives, as this allows for at least two pairs of mirrored drives. Using fewer than four drives would not provide the necessary pairs to create both mirroring and striping. Thus, the requirement of having an even number of drives with a minimum of four drives is essential for RAID 10 setups on an HP Z Workstation to function effectively.
