I know the next gen has just started, but I buy a lot of games and download a lot as well. I pretty much used my 500GB rather quickly. I came across this, bought it and installed it. It fits perfectly, just the process of removing the 2TB HD is annoying to remove from the external casing. There is a review in the link of how to remove the hard drive carefully. For $100 this is an awesome deal!! If you have the Far Cry cover Game Informer, it explains how to remove your 500GB HD and replace it with your new one. :)
Personally I feel that this is great to have being over this generation I will need tons of space due to the size of games. Has anyone else seemed to have a space issue and considering to buy this? Hope this was some sort of help to some people!
