Neither one is parallel, right? As I understand them, they look like
SCSI once you get up to the packetized commands and responses, but
nothing like it below that.
The major reasons I prefer SCSI amount to "simplicity". Like USB
versus real serial ports: I can interface to a serial port using
discretes (though a little SSI helps); I can count the transistors
used. It's really hard to speak USB without thousands-to-millions of
transistors. (Admittedly, USB can do more than a serial port. This is
most relevant when trying to do the simple sort of task that a serial
port can serve for. It's a little bit like firing up a full Lisp
engine to add 3 and 4.)
In SCSI's case, the protocol is complex enough that the comparison
isn't so clear-cut, but the basic pattern I see is more or less the
same. Have I misunderstood?
