The RD54 is a Maxtor XT2190, which, as you say, is quite similar to
the XT1140. Both have 15 data heads (eight platters), but the XT2190
has a higher cylinder count (1224 vs 918), reportedly at least in part
due to use of a better head design.

Maxtor pioneered the use of the drive motor integrated in the spindle,
which is what allowed them to fit eight platters into a 5 1/4" drive
in 1983, when other vendors were limited to four platters.
