There was a nice paper published recently (at OLS or maybe I got the link from one of OLS presentations) about an "iron ext3", ext3 modified to withstand various data corruptions caused possibly by hardware failures. In there is also a nice table with comparisons on how different linux file systems stand up to those corruptions:

Very good reading to anyone who's concerned about digital data storage.
Also, for discussion about cheap storage there's a mailing list called "linux-ide-arrays":

But remember ... "Cheap, fast, reliable. Pick any two, you can't have all three" ... is even more true for storage than for anything else ;)
