SK0-004 · Question #165
A new server has two drives and a RAID controller. Which of the following is an option for configuring the storage on this server?
The correct answer is A. RAID 0. With only two drives available, the only viable RAID level from the listed options is RAID 0, which requires a minimum of two drives. RAID 5, 6, and 10 all require more than two drives to function.

Why each option
With only two drives available, the only viable RAID level from the listed options is RAID 0, which requires a minimum of two drives. RAID 5, 6, and 10 all require more than two drives to function.
RAID 0 stripes data across a minimum of two drives, distributing read/write operations to improve performance, and is the only option listed that can be implemented with exactly two drives. While RAID 1 (mirroring) also requires only two drives, it is not among the answer choices. RAID 0 is the only valid selection given the two-drive hardware constraint.
RAID 5 requires a minimum of three drives to distribute parity data across the array, so it cannot be configured with only two available drives.
RAID 6 requires a minimum of four drives because it uses dual distributed parity to tolerate two simultaneous drive failures, making it impossible with only two drives.
RAID 10 (1+0) requires a minimum of four drives - at least two mirrored pairs that are then striped together - which exceeds the two-drive limit of this server.
