Keion works as a freelancer creating websites and designing logos for clients. He recently had a hard drive failure and lost work for a client, and he would like to prevent the same type problem from happening again. Keion does not want to rely on a backup but would like a way to ensure that his data is safe on his computer. You recommend that he create a RAID array that will duplicate his work onto two disks.
What RAID configuration should you recommend to Keion?
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 10

Question

Quizplus · Accepted Answer

RAID 1 is the correct choice because it mirrors the data across two or more disks, providing redundancy and ensuring that if one disk fails, the data is still available on the other disk(s). This setup is ideal for preventing data loss due to hardware failure, which is Keion's concern. RAID 0 focuses on performance and does not offer redundancy. RAID 5 requires at least three disks and provides redundancy through parity, not duplication. RAID 10 combines the features of RAID 0 and RAID 1 but requires a minimum of four disks and might be more complex and costly than necessary for Keion's needs.
