Just wanna say in my experience ATA drives are NOT reliable. What percentage
of drives have you noticed fail in a year? Because all but one of my IDE
drives have failed. So thats 4 gone bad, 1 is still working.
2-3 per year in over 300 systems, none in our own systems in the
office. Drive failure is rare, but we really push people to get
UPSes and we don't buy used drives (well, I do, sometimes. That
drive's been going pretty much 24/7 for two years now, not a hiccup.)
If you're killing three drives in less than a year you're either
getting them from the wrong source (someone selling substandard
drives) or are doing something else to 'em, because, frankly, drives
a lot more robust than that.
Just to add to Bruce's reply...
In general, the drive mechanisms used in IDE/ATA drives are designed
for desktop use - frequent stop/start cycles. SCSI and FC drives are
designed for servers - longer reliability with fewer start/stop
cycles. ...This line is becomming blurred as 15Krpm, non-bridged
Firewire, and SATA use becomes more prevelant in both desktop and
server boxes.
That being said... My overall reliability experiences with ATA drives
<120 GB is about what Bruce describes: failures are rare. But with
these new 200 GB+ drives... ug. Between me and my clients, we've had
8 deaths so far this year. They're just not living up to even 1/4
their MTBF.
So far the manufacturers have been reasonable regarding swapping them
out. And their replacments seem to be (knock wood) more reliable
than the originals.
FWIW,
