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.'"

  1. My drives work great ... by buchner.johannes · · Score: 0, Offtopic

    My drives work great ... until someone comes along and puts stickers on other drives that say they are more "ready" than my drives.

    No Offense, but I currently have a Core 2 Quad, 4 GB RAM, 2 500 GB Seagate Drives, 1 250 GB Hitachi Desk Star, 1 80 GB Maxtor, a GeForce 8800 GT and i'm pulling 270-300 watts while GAMING. My PS is a 430 watt antec and i've had 0 problems from my rig in general, and i game A LOT. I also overclocked my Core 2 Quad to 3 Ghz recently. The system is rock solid stable. I've NEVER lost a hard drive. Even the hard drive in my old IBM PS/2 still works. The key is a nice clean energy source and proper cooling.
