So serious question on what people feel will be the best approach for storage? Will you simply attach an external hard drive; opt for an SD card; or USB drive (does it support USB drives?). Are there any performance considerations that we less technical folks need worry about (i.e. I've read USB 2.0 is not fast enough for good game performance, but then also have read that it is still faster than reading off an optical disk drive so it will be fine for games. Thanks for the help/opinions!!
