Study says failure rates 15 times that of what manufacturers indicate
 

A study released this week by Carnegie Mellon University revealed that hard drive manufacturers may be exaggerating their mean-time before failure (MTBF) ratings on hard drives. In fact, researchers at Carnegie indicated that on the average, failure rates were as high as 15 times the rated MTBFs

interesting...

ot they just quoted the google results


but the important thing is this:

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.

people don't buy SCSI/FC disk for lower replacements, they are already running in RAID 5 at least, with support contracts to swap the disks without cost if one breaks down. :)

As I recall the Google results differed a good bit in some areas, especially in regards to temperatures.

google results indicate lower temps give higher failure...
