Now just suppose all the work that's been put into developing successive
generations of IDE/ATA had been put into improving SCSI instead, and
building less expensive SCSI hardware. It's interesting to speculate
what the price/performance of SCSI would be right now. I'm betting it'd
cost little, if any, more than IDE does.
I gotta admit, though, it'd be sweet to get rid of all these damned
ribbon cables and have little tiny 8mm ISDN-ish disk cables instead.
Imagine how much less cluttered PC cases would be if instead of being
full of airflow-blocking 50- and 68-pin ribbon cable, you just had an
input and an output port on each disk and little jumper cables that you
plugged from drive to drive, with an active terminator plugged directly
into the last disk's output port.
