Reed-Solomon
Last modified: Thursday, October 23, 2008 

Abbreviated as RS, Reed-Solomon is an algorithm for Forward Error Correction (FEC) that was introduced by Irving S. Reed and Gustave Solomon of MIT Labs. It does not specify a block size or a specific number of check symbols, instead these variables can be set to the best variables for each transmission medium. Reed Solomon codes are used in a wide variety of commercial applications such as CDs, DVDs, and in data transmission technologies like DVB and WiMAX.

Reed-Solomon Coding for Fault-Tolerance in RAID-like Systems
It is well-known that Reed-Solomon codes may be used to provide error correction for multiple failures in RAID-like systems. The coding technique itself, however, is not as well-known. To the coding theorist, this technique is a straightforward extension to a basic coding paradigm and needs no special mention.
