Look again.  The standard IBM controller handles two 10 MB disks.  They
even provide the cabling; all you have to do is take the second drive and
plug it in.  There isn't physically room in an XT for two hard drives and
a floppy, though, so you need an expansion chassis, which is expensive, or
else some half-height drives.

I have personally plugged two drives into the controller many times (in an
expansion box, because we had them) and it works just fine.
