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.'"

    Wait. You've got a huge Wang, and you're throwing it out? D00d, that's just uncool. Give it to someone else at least. It would be fun to ask people "wanna come see my huge Wang?" just to see their reaction! :)

    I'm about to lug a huge Wang hard drive out to the trash pickup on Monday - weighs over 100 pounds... still runs. Actually it uses removable platters but still...

    The only possible response to that is this Penny Arcade.
