| 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 http://www.dailytech.com/article.aspx?newsid=6404

| 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.
