Why not? A lot of companies operate that way. Less expenses for
studies, research, not having to come up with anything ground breaking
in their field, cheaper parts, cheaper labor and so on. That is
unfortunately a fact in every industry, including computers and
hardware.... which explains why some brands and models suck.

What I wonder is this. Semi-hypothetical.

Imagine that Maxtor makes a line of high quality SCSI hard drives and a line of cheap low quality EIDE hard drives. Since the stuff that spins is pretty much the same in each, why go to the expense of designing two of these instead of just one? Why not use the same for both. Of course, they could just skip the testing of the cheap ones.

The PC boards would probably have to be different, unless they just put a different ROM and connectors in one than the other. But I doubt the electronics are that simple.

and the mechanical parts I have not had the nerve to examine. I assume if I open a drive
to see the platters and the heads, etc., that dust would get in. Maybe
I will open one once one fails.

Well, I've taken several apart once they've completely failed, but never
one that wasn't dead already. I have taken one drive with a bad circuit
board and good data, and taken the circuit board off the same drive
model of one that had the data gone, and saved a drive that way without
any hassle or having to expose it to an unclean environment. Also,
some soldering work on another one, but never fully opened up a working
one to that sort of degree. Ironically, these were all WD drives.

Did you happen to take apart both a SCSI and an EIDE/ATA drive? If so, could you detect any difference in quality and workmanship between the two?
