Standard RAID levels - Wikipedia, the free encyclopedia
according to this article, the probability of dual disk failure is 0.0004%
one of our servers at work had a disk crash yesterday and we found out that it had been set up in raid 1 (mirror/mirroring) so there was no need to try to retrieve the data from the crashed disk (it was easy to do using linux) because all we had to do was put in a new disk and then it copied its index to the new disk and everything started up fine as if nothing had happened. sweetness.
