Well, if you want to use SATA you have to buy a SATA HDD. They have a complete new connection method. From my understanding there is no converter from parrallel (ultra) to serial ata. The SATA hdd are generally 10 - 20 $ more expensive than your regular hdd. They have their own cables (which new Mother boards come with) Very nice cables by the way, slim and and compact. THere is no Master and Slave option, so each hdd has its own cable connection, which obvisouly results in better performance. They power connection cable is also new and you can get a converter for that one from the normal power supply 4 pin power to the new slim design of the same cable. I dont know if all of the SATA hdd have that new power supply connection, but my seagate does and it makes it look more compact and stylish.
