Fw: Disk Failure Rates More Myth Than Metric

Lucas123 writes "Using mean time between failure rates suggest that
disks can last from 1 million to 1.5 million hours, or 114 to 170
years, but study after study shows that those metrics are inaccurate
for determining hard drive life. One study found that some disk drive
replacement rates were greater than one in 10. This is nearly 15 times
what vendors claim, and all of these studies show failure rates grow
steadily with the age of the hardware. One former EMC employee turned
consultant said, 'I don't think [disk array manufacturers are] going to
be forthright with giving people that data because it would reduce the
opportunity for them to add value by 'interpreting' the numbers.'"
