I think it's exactly the other way around. High demand, home use
products tend to become commoditized leading to cheaper and cheaper
manufacturing processes as right through the supply chain there is
I've got to say that apart from a few IBM's that I salvaged out of a
IDE RAID unit for home use, which eventually failed, and came as no
suprise that my disks at home have generally only been retired due to
size constraints. With SCSI this isn't a problem, IDE you are somewhat
limited (without performance loss) to a single drive per channel. I've
been through 2x40GB (IBM DeskStars) to 2x80GB (Seagate Barracuda
III's) to 2x120GB (Western Digital Caviar). replaced at approximately
12 month intervals on a machine that rarely powers down and has
filesystem integrity checks done every month or so. Typically I find
that at retirement they are in about as good condition as when they
I have found that IDE disks that get very heavy read/write tend to die
much faster than SCSI. As an example the h/w IDE RAID in the office
which used 6 disks in RAID 5 and was getting hit very hard 24 hrs /
day would chew a disk about once a month.
