The cost per GB for two 1TB is the same as one 2TB. Unless you need more than 1TB which is a lot, I would buy a 1TB drive and keep the budget for another drive in the future. Who knows by the time you run out of your 1TB, you could get another 2TB a the same price.
The bottle neck will now be the data transfer, USB 2.0 is just not fast enough.. so look for eSATA. Your PC/Notebook should also have an eSATA port. A NAS box with Gigabit Ethernet would also be fast, provided your network card and your network is 1GBps.
