Sata is the future of hard drives. if you are planning on getting buy an new MOBO, make sure it has SATA on it.
I got one of my flatmates that is in the process of upgrading his computer. He was thinking of getting a new hard drive from me, but when i told him half the stuff i heard from this SEAGATE launch last week, i have convinced him to wait until he has money for the new MOBO + CPU + RAM first, with a SATA hard drive.
