Don't be surprised if your Seagate does start to chatter after a few years though. I've had mine and it's gotten louder here and there, but it still is a very rock solid, stable drive.
If you're going SATA, make sure you have all the bells and whistles too such as NCQ2, SATA2, etc, depending on what you're looking for. This way, when you do upgrade your controller that supports all those features, you'll be able to take advantage of them! PATA drives generally will not have the fancy features SATA will. So if you are looking for a PATA drive, any Seagate will work fine. WD's are dodgy unless you have to spend the big bucks on the raptors (overrated in my opinion).
