 RAID 60 with two parity groups: Capacity of four drives

 RAID 50 with two parity groups: Capacity of four drives

 RAID 10 with four drives: Capacity of two drives

 RAID 1 ADM with three drives: Capacity of two drives

 RAID 60 with two parity groups:

RAID 60 is a combination of RAID 6 and RAID 0. It uses double parity (RAID 6) for fault tolerance and striping (RAID 0) for performance.

With two parity groups, it means there are two sets of RAID 6 arrays, and each set needs two parity drives.

Therefore, the capacity overhead would be the equivalent of four drives used for parity.

 RAID 50 with two parity groups:

RAID 50 is a combination of RAID 5 and RAID 0. It uses single parity (RAID 5) for fault tolerance and striping (RAID 0) for performance.

With two parity groups, it means there are two sets of RAID 5 arrays, and each set needs one parity drive.

Therefore, the capacity overhead would be the equivalent of two drives, but considering both groups, it would be four drives.

 RAID 10 with four drives:

RAID 10 is a combination of RAID 1 and RAID 0. It mirrors data (RAID 1) and stripes it (RAID 0).

For four drives, RAID 10 effectively uses two drives for data and two drives for mirrored copies.

Therefore, the capacity overhead is the equivalent of two drives.

 RAID 1 ADM with three drives:

RAID 1 ADM (Advanced Data Mirroring) typically involves three drives where each piece of data is mirrored across all three drives.

Thus, the capacity overhead is the equivalent of two drives being used for mirroring.
