I thought there was no such thing as a MFM or RLL *drive*. I thought that
you only had MFM or RLL *controllers*. The important thing on the hard
drive was the *interface* (in the case of the MiniScribe 3438, a
ST412/ST506 interface).
I seem to have a dim memory of RLL controllers being sold as a way to
increase (double?) your disk space.
As I remember, RLL controllers were much more fussy about cable length and
media quality than MFM controllers, which meant that they didn't work all
that well with cheap hard drives.
Of course, I could be completely wrong...

That is sort of true. Amongst ST-412/506 interface drives, there were RLL
capable and MFM capable. Essentially, all RLL capable drives could be
used with an MFM controller. However not all MFM capable drives could be
used successfully with an RLL controller. As a matter of (sloppy)
shorthand, folks refer to RLL and MFM drives.
