Which RAID level provides the most redundancy?
A.
RAID4
B.
RAID5
C.
RAID1
D.
RAID0
Explanation:
RAID Level 1 is called mirroring and also requires two RAID Partitions. The resulting RAID device
is virtual partition the size of the smallest of the member RAID partitions. All RAID partitions which
are members of the RAID device contain identical data. IF any disk in the RAID device fails, the
RAID device continues to function without losing data. This is useful for fault tolerance, but is
costly terms of disk space.
