This has nothing at all to do with the drive.  MFM or RLL is simply the
method used by the *controller* to encode data that is sent to the drive.
The only difference in the drives is that RLL-compatible drives tend to
be a bit more expensive than their non-compatible brethren, as RLL demands
slightly tighter tolerances than does MFM.  For example, the Seagate 225
drives are something like $25 cheaper than the Seagate 238 drives, and the
only substantive difference between the two is that the 238 is RLL certified.
So, if you can find an RLL-compatible drive at a real good price, you
shouldn't hesitate to go for it; at least, not because it's RLL.
