Once core memory became common, fast speeds are relative to other I/O
at the time, of TTY and punch card speeds.
Actually, the FASTRAND was used on the 1107 machine which used thin-film
memory, so memory was pretty fast already.
Didn't the FASTRAND have "ping" detectors that would register a count
every time a head hit the surface? I recall that the binary-encoded
positioner mechanism was composed of a bunch of solenoids and levers
that could convert a binary input to a head position. (The FASTRAND was
a moveable head, not a head-per-track drum).
