I might confuse things with parity here, but does any of the RAID levels except RAID2 employ any means against silent bit corruption in the data? What about checksumming? I am not talking about hardware failures of any sort.

From Wikipedia:
RAID 2 is the only standard RAID level, other than some implementations of RAID 6, which can automatically recover accurate data from single-bit corruption in data. Other RAID levels can detect single-bit corruption in data, or can sometimes reconstruct missing data, but cannot reliably resolve contradictions between parity bits and data bits without human intervention.

1RAID 3, RAID 4, RAID 5, RAID 6 all provide some sort of byte/block/bit striping and some sort of parity. – Ramhound – 2011-12-28T16:44:01.900
