storage vendors have a credibility problem. i think the big storage vendors, as referenced in the op, sell you on many things you don't need for much more than one has to spend. so i understand one is not inclined to believe a storage guy about the need for something that's more expensive. however, unlike your refrigerator, the hard drive vendors claim different reliability numbers for enterprise drives than consumer models. they claim (a) lower ure rates (b) greater mtbf (c) 100% duty cycle. typical enterprise drives today have a 10x smaller claimed ure rate, 2-5x greater mtbf and are warrented to run 100% of the time. you may not believe them, but when we see drive failures, chances are very good that it's a consumer drive. from what i can tell without any nda access, there's different hardware on enterprise drives. there are different chips on the pcbs of most enterprise drives, claimed extra accelerometers and temperature sensors (to properly place the head). - erik
