I would probably just find the best GB for the buck from western digital, segate or hitachi. Samsung are suposed to be good too but I'm not farmiliar with them. I would avoid maxtor though. All drive manufactures have had good and bad models, and quality has gone up and down (the nature of hard drives I guess). I wouldn't fault a company because they made a bad drive model (because at some time, they have all made a bad model). I honestlly don't think the drive manufactures have a good and complete picture of how good the drive is till the users have used it for a while.
I dislike maxtor because they have show a track record for a few years of crap drives (not all models but many). I have maxtor drives that are older than that that work perfect and I trust them (even though several years old). Some have claimed that the newer maxtors are beter, but only time will tell, and I'm not going to be a guinea pig.
storage review is a very good site to check out a particular model of drive (you need specific info on the drive, and have to enter info for one of your drives before you can see the reliability survey, but trust me, it is worth the effort).
Fyi, if you are not in a hurry, hard drives defanatlly seem to be a loss leeder item at many stores. They are willing to bulk purchase or sell below cost to pull customers in. If you are patient, there are some incredible deals on hard drives locally (in the US). frys (as mentioned) is a great place to look. They had a maxtor 300 gig (pata or sata) which was a good price at the time (prices seemed to have dropped in the last few months), for 80 or 90$ (cannot remember), no rebates. As I had to go to micro center for a gpu cooler, I asked if they would price match. they said that they would if it was not below cost. I probably wasn't suposed to be looking over his sholder looking at the screen, but thier cost was about 130$. So I went to frys and got it, and they had a whole pallet of the pata drives (bulk purchase for low price I am guessing if one store had a pallet of them on the floor). Also, having a friend that works at fry's (and thier employee discount is based on margin), certain ad items are sold just above cost, at cost or just below (they don't loose much money as it is just below cost so they can sell a lot and hope you buy something else I'm guessing).
Look for the deals. There have been a lot of segate deals lately and current segate drives are very good and carry a 5 year warranty!!!!
