SATA is pretty much IDE with a few features added (like NCQ) and a new
physical interface. The physical interface is the issue. It's serial,
differential, and VERY fast (lowest spec SATA is 1.5Gbps).

Your interface options are as you've discovered, with the addition of
FPGAs. MANY cheaper FPGAs now contain the necessary hardware to
interface to SATA.=20
