Detailed explanation-1: -To implement RAID 10, you need at least four physical hard drives. You also need a disk controller that supports RAID.
Detailed explanation-2: -RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. It requires a minimum of four disks and stripes data across mirrored pairs.
Detailed explanation-3: -The minimum number of disks in a RAID4 group is two: at least one data disk and one parity disk. However, for non-root aggregates with only one RAID group, you must have at least 3 disks (two data disks and one parity disk).
Detailed explanation-4: -RAID 5 groups have a minimum of three hard disk drives (HDDs) and no maximum. Because the parity data is spread across all drives, RAID 5 is considered one of the most secure RAID configurations.
