In short RAID 5 can survive one disk failure, but not two or more. Update: See why RAID 10 is better choice for database server instead of RAID 5 for performance and reliability.

However, to cover your larger question, RAID1 can (maybe) handle two disk failures -- technically, an N disk RAID-1 array can handle N-1 failures, so whether a given RAID-1 will handle two failures depends on your configuration. can potatoes over winter in the ground
