Interrupt driven mass storage was (and is) pretty
uncommon, because it
requires so much CPU. But of course, for those who do, you transfer only
at interrupt time, so you are not bound by the disk speed anyway.
For other systems maybe, but for the PDP-8, not so much.
And of course, you also have things like OS/8, which
runs with
interrupts off at all times, to which the answer to the original
question would be "OS/8". :-)
Exactly :-)
