CMU released a study comparing the MTBF enterprise class drive with consumer drives, and found no real differences. >From the study: "In our data sets, the replacement rates of SATA disks are not worse than the replacement rates of SCSI or FC disks. This may indicate that disk-independent factors, such as operating conditions, usage and environmental factors affect replacement rates more than component specific factors." Google has also released a similar study on drive reliability. Google's sample size is considerably larger than CMU's as well.
