Jack has three hard drives in his Linux system available for a RAID array. Which of the following RAID levels can he configure with these drives?
  1. RAID 0+1
  2. RAID 1+0
  3. RAID 5
  4. RAID 5+1
Explanation
Answer - C - You can configure the RAID 5 level using these drives.

Key Takeaway: RAID 5 stripes both data and parity information across three or more drives. The performance of a RAID 5 array can be adjusted by trying different stripe sizes. RAID-5 requires at least three and usually five disks for the array. It is best suited for multi-user systems in which performance is not critical or which do few write operations.
