I didn't do the math recently, but around a year ago when i did it was something like that--ridiculously improbable that you'd still be using the media by the time it failed (though i still have some 15 year old hard drives, i haven't used any of them in at least 10 years...and no longer have a computer with the appropriate ancient scsi connector to do so if i wanted to.) first off, the drives are pretty smart about spreading writes around the drive rather than leaving hotspots pinned to a certain sector. but even if it is pinned to a spot that exceeds the write limit, these drives also typically have some reserved percentage above their listed capacity to migrate failing sectors to, and they notice the failure when it happens and do so automatically under the hood so you don't even ever become affected by it, except that maybe the write takes an extra few milliseconds to complete. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
