27ft/s seems high, see here:

Many years ago [50] in school physics we were told 27 feet per second
for 'electrons' in wire and to treat "data/information" transfer like
a long tube full of ping-pong balls where you push one in at this end
and one falls out at the other.

What I find particulary amusing is that the drift velocity of the
actual electrons is of the order of a cm/s if I remember correctly. Jens

Yes, that is correct! Because electricity travels
through a wire at the approximate speed of 1 nanosecond per foot!

Processor chips
may have gotten a little bit bigger but not by much but could you
imagine the size of a computer based on the ENIAC
<https://en.wikipedia.org/wiki/ENIAC> technology and the power
requirements? The original consumed 150KW and weighed about 30
tons, a
modern day version would need its own power station and would take
up a
football stadium
Ah but you are forgetting as Admiral Hopper liked to point out, the
size
of a nanosecond. A football stadium sized computer could not get out
of
it's own way.
