Wear on a hard drive is caused by bearing wear. A drive running
at 4200 or 5400 rpm will last much longer than a drive running at
7200 rpm or faster.
The same thing with any mechanical item, like a car's engine - wear down
the bearings and it dies. The faster the engine turns, the sooner it dies.
Same with hard drives.
So I thought id ask here to see what your opinions/experiences are
regarding this. My worry is that I am about to add a 200GB drive, this
will hold a lot of files (and will be on for ages) but will not have any
redundency so i'm worried about it failing.
If it's an IDE drive running at 7200 rpm or faster, with continous running, it
should be replaced every 1.5 yrs. If it's a SCSI drive running at 10,000 RPM
or faster continously, then replacement should occur in 2 yrs. Yes, I know
about warranty and all. If you have a good backup system and don't mind
having a drive offline for hours on end until the restore is done, then wait
for it to die.
If you have a RAID 5 or better, just wait until the a drive dies.
