Have currently got a Maxtor 160 GIG Sata 2 HDD and it's fine, I know your mobo doesnt have sata 2 but I honestly don't think Maxtor are all that bad. I also have 2 x samsung drives, 1 is a 160 gig and the other 120 gig, and also a Western Digital 120 gig drive aswell.
Out of all the drives I've got the Western Digitals have been the least reliable.
