It won't give you any speed advantage either. Your IDE connector won't run SATA speed just because there's an IDE -> SATA converter attached.
It'd be like having a 52x CD-R drive running off the USB port
You'll never acheive 52X on that thing... USB cannot transfer data that fast...
Same thing here... even if you do get a IDE->SATA converter (which I have seen @ frys (for Desktop pc's only i might add) ), The best speed you'll get is whatever the IDE interface can get... not what the SATA can do.
