I am assuming you are looking for a 3.5" hard drive. If your budget is small and you only need a small hard drive like you said you could get the
Western Digital Caviar Blue 80GB. Western Digital is actually a very reputable hard drive company.
For 20 Dollars more you could get the
Western Digital Caviar Blue 640GB (currently the highest rated hard drive on Newegg). There is no need to worry about either of them bricking as the 80GB comes with a 5-year warranty and the 640 comes with a 3-year.
If you have a few hundred dollars to spend, I would highly recommend getting an SSD such as the
Intel X25-M 80GB for your OS and programs. It will speed up load times by a ton.
