All the major ones are good. Its just certain models from each compamny that either suck or rock. Look at reviews from non-partial sites. Check out reviewers on Newegg and such. I personally always hated maxtor but I recently bought a few of their Maxline III Sata HDs w/5yr warranty and am happy with them. I loved Seagate but both of my 7200.8 died recently. Its all a matter of what model. All companies make good drives as well as bad ones.
