Shop around at various online retailers to find the best deal. Someone mentioned RAID for safety and speed - caution, it depends (plus speed is overrated for listening to music). RAID 0 gives you great speed but offers no safety - if one drive fails than the contents of both drives are lost.

I have a media PC with four TB drives in it. I went with Western Digital "Green Power" drives for lower energy use, quieter operation and cooler temperatures. The four drives are arranged as two RAID 1 pairs (each pair acts has two drives with identical content). My media PC case won't hold any more drives so my next step is to move to network storage - either a PC file server or a dedicated network device (I've only just started on the second array so I've got a while to go, plus I keep videos on DVDs for now). RAID 1 has the slowest speed, and the Green Power drives are slower than other drives but I'm able to listen to 48/96 FLAC files with no problems.
