RAID 1 or (mirroring) is meant for redundancy not performance.An even number of drives are needed for this configuration since the drives are mirrored onto each other for the purpose of redundancy. If you have 2 drives in your RAID 1 array and one drive fails your data is still safe on the other drive.
When most people hear the word RAID they imagine this type of array and think they are now bulletproof against data loss. The main reason they end up needing data recovery is due to the fact that the RAID goes unmonitored allowing multiple drives to fail. A perfect example is a 2 drive RAID 1 array where 1 of the drives failed quite some time ago and goes unnoticed allowing time for the second drive to fail which results in catastrophe.
