The controllers I have examined or used (Xebec, WD, Adaptec) have separate
jumpers for each drive, so you CAN use different size drives. This feature
is supported by the ROM BIOS on the controller card.

Actually, there is a 34 pin cable (the data cable) that connects to both
drives, and a 20-pin cable (the control cable) for each drive.
Also, don't forget to remove the termination resistor pack on all drives
except the last one on the 34-pin cable chain. Things usually work without
this precautionary measure, but the drive and controller makers want you
to do it anyway.
