I don't know if you guys are aware of what's new in the data storage space. Expensive still, but great; the new computer models sporting solid state hard drives had made their appearance in the market. The new "disks", differently to the ones that we are used to see on our machines, are more or less flash memory banks like a "pen or thumb-drive"; but with more capacity and a higher read & write speed. A good example of what can be achieved in term of design with these new hard drives is the MacBook Air. Check out Apple and Sony models with SSDs.
