Which RAID level best meets this customer’s needs?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 6
Correct Answer: A
Explanation/Reference:
Industry Standard Architecture – Student Guide 1 – Page 225:
RAID 0 — Disk striping
RAID 0 is not fault tolerant and is often used in situations that are not mission-critical, where performance and capacity are more important than uptime. RAID 0 is the only non-fault-tolerant RAID level supported by HP.
Because RAID 0 has no overhead associated with duplication of information, it provides the highest performance. Both read and write requests can use all member disks simultaneously.
