Is that why SCSI HD prices always stayed higher than IDE? Controllers
too? I don't think the limited adoption of SCSI was as much determined
by industry as it was by the market, unless industry was artificially
keeping SCSI prices high. But why would they do that?
Well, SCSI was always faster than IDE of the same generation. This
meant that it took more cutting edge chips and cables. It also took
terminators (until active termination took hold about 1989).
This all adds into expense.
In addition, IDE controllers often published their controller specs and
people could write better drivers. I remember the BusLogic SCSI
controller being one of the best Linux SCSI controllers precisely
because BusLogic was willing to give out their controller programming info.
Alas, BusLogic got bought by Adaptec ...
