Agreed, someone recently posted that for a raid-5 composed of 1TB drives the odds of a rebuild failure are 1 in 67 even if the remaining drives are within spec. (ie. the unrecoverable bit error rate is slowing succumbing to the ever increasing size of drives.) You have 500GB drives, but you have 3 left to rebuild from, so that's 1.5 TB your trying to read. I'm not sure how the original calculation was done, so your odds of failed rebuild were either 1 in 134 or about 1 in 42. Either not very good for something that is supposed to protect your data.
