After looking at prices, I think I'm definitely going to go with a SSD for my OS/App drive. 128 aren't too bad in price and from the looks, does wonders for performance.
As for my storage drive, should I look at possibly the WD Caviar Green? I know the Black has the highest performance, but if it's just storage, maybe not needed. I do plan on doing some coding and video editing so I would be read/writing often so the better performance with the Black might be good.
