Couple things, compact flash is IDE. Any vintage computer running CompactFlash as a hard drive will be fast. Vintage I/O is slow. CF CompactFlash to IDE adapters are nothing more than a pin to pin . CompactFlash adapters should only be a dollar or maybe slightly more. Also keep in mind there are various speeds of CompactFlash. If you'd like to obtain some inexpensive CompactFlash , then go to the bay and type in compact flash lot . I bought like 10 CompactFlash cards for next to nothing . They were used but they all formatted and tested perfectly .
