I am not interested in RAID. RAID increases availability, but does not
archive data
You have a mirror - that's RAID. RAID is about smoothly surviving
drive failures. With any storage system there are two important factors -
mean time to data loss and probability of data unavailability.
Ignoring whether its RAID or not, mirroring will protect you against a random failure of one of the drives, which was more useful in the spinning rust days when random mechanical failures were an issue.
With SSD, write life is the main issue, and if you have two identical mirrored drives, you may find any write life issues, which are not random, occur at exactly the same time.
So with any type of mirrored arrangement, make sure they are different makes or models of drive, so it is less likely they fail together.
