Please don't forget that data transfer rate is heavily influenced by
lots of factors, including track-to-track seek time, and the interleave
factor.  I had a drive interleaved at 3 in my (XT-class 8MHz) machine;
it would only give a transfer rate of 25K/sec, according to CORETEST.
I reformatted it with an interleave of 4, and the transfer rate went up
to 130K/sec, over a tenfold increase.
