I can enjoy playing games online now, because before online updates wouldn't fit on my XBox Arcade hard-drive. I can also download apps, now that I am on XBox live. I have downloaded so many things onto the USB, and it still has about 6 GB remaining. Even better thing about this product is that it is completely portable, I can take it around with me and use stored apps and saves on other XBox.
I didn't opt for the 16GB USB because you don't really need so much space, unless you're a hardcore game, which I am not. Also it is aboUt double the price of the 8GB option. All in all, it is for me the best option if you need extra storage for your XBox. GREAT BUY!!!
