These OptiBay‘s are an awesome idea. For $200 you can get a 1TB drive to replace your internal cd/dvd drive and a case to make the superdrive external. The going cost for a 1TB drive is a little over $125 and the knockoff versions without the superdrive case is around $30 so all in all this seems like a great deal. I only have about 80GB free on my brand new MacBook Pro’s 500GB harddrive so I am in the market for more storage, I already have external drives). I think this will be something I look more seriously into getting once the new year starts.
