All newer motherboards support SATA, so you can go for SATA.
SATA is theoritically faster than PATA, greatly removes the Cable clutter (only 7 conductor cable), SATA drives have CRC check on data and commands also, so data protection is more.
PATA drives offer speeds upto 133MBytes/Sec and they have already reached the limit.
But SATA drives start from 150MBytes/Sec, and in near future they can go upto 600MBytes/Sec.
