1x 128GB Crucial M4, because it's one of the most reliable SSD's
1x 1TB WD Green ( WD10EARS)), to store music, movies, etc, which don't really need high performance and the Green is a cheaper drive
1x 2TB Seagate (7200.14), to store games, VM's and other stuff I don't want on my SSD (browser cache, etc). I would have liked to buy a WD Black for this, but that one was too expensive in my opinion, so I went with the cheaper Seagate alternative.
