Meh... You could say the same thing about single ended SCSI though.
Sure...then we moved to LVD.
There was a brief hop to just differential SCSI (higher voltage then LVD
which is how LVD got its name). HVD and SE/LVD don't like each other while
the other SCSI standards did with some tweeking.
The
reason SCSI was able to last is that it continued to evolve. Parallel
ATA on the other hand, evolved differently, mainly because of the
consumer computer market.
