[quote name='metaly']Thinking of picking one of these up to maybe use on my friends' 360s and then my own later on. Sorry for being totally Xbox-ignorant, but can I store just my profile settings on the memory unit and keep all my save game data on the HD? Also, is the 64MB unit worthwhile? I noticed at the store they had a 512 unit with free Worms, which is always welcome.[/QUOTE]
I actually keep a lot of my save data on the MU, too, so I can have access to it elsewhere. Save data is pretty small, and I keep all the DLC on the HDD. The 512 is definitely for people without hard drives.
