You can use SD cards and USB HDD's to increase the storage.

You can use any standard USB hard drive?

Yes.

No, they won't.   Law of diminishing returns hits pretty heavily after 2 GB on a home console.

Hope I'm not asking for too much but could you go into a little more detail as to what you mean by this?

Once you get to a certain point, you no longer gain any benefit from having more RAM.   Say, for example, your stage, textures and gamecode take up 1 GB...what benefit do you get from having 2 GBs?   Say you max out your rendering capabilities with 2 GB's of RAM.  Another GB won't do much for you.

These are very simplistic examples simply to make it easy to grasp my point.  Actual details are much more technical.

This is further exasperated by the proliferation of texture streaming.
