The difference between MFM and RLL drives is like the difference
between single-sided and double-sided 5.25" 40 track diskettes.
Physically identical, but the higher capacity item has been
certified to function with the additional storage capacity. A
Seagate ST-225 and ST-238 (for example) differ only in the label.
An ST-225 on an RLL controller holds 30 Mbytes instead of 20, but
Seagate will not warrant that operation and if you lose data,
tough cookies. In the same way an ST-238 on an MFM controller
only formats out to 20 Mbytes.
