Hitachi Hard drives are going for a bargain at the moment:

You can also cheat a bit by exploiting a partition. Since data is recorded on cylinders, and that hard drives are organized to read/write to the outside first (which is why they are somewhat faster new), you can make a 'small' partition first for your operating system and applications, and a second partition for your data.
If you make a 300GB partition with a 2TB 7200rpm drive to store your OS, you'll actually be out performing the 10,000rpm drives of the same size--in that partition.
It's a clever trick.
