This Xbox 360 memory card is a smaller memory card. Regardless, this 64MB card works great if you're transferring a profile to another 360. You can also transfer photos from your hard drive to a card and then to another system. This card is worthwhile if you want to transfer your profile to an additional console. So you can play games like Gears Of War 3 etc. with system connection instead of split screen. Instead, my son and I played split screen games (although we have 2,360 and 2 sets of Gears 1-3). So I finally managed to get this card so I could put my SN profile in his system with Gears saves. Then play the system link, each has a full screen in horde and campaign mode. However, you cannot copy a profile and use it on both systems. This will remove your profile from the original one. However, you can always revert it back to the original system. Also, I don't think you can use them on the new ("thin") 360s. My brother has a newer system and wanted to transfer music from my hard drive to his but we couldn't. I would still recommend buying this memory card. Especially at Amazon prices! You can place a profile on your map. Plug it into your desktop/laptop and copy the profile to your processor. Then save the profile that is still on the card to the hard drive. If so, that would be great as a backup. My old profile somehow got corrupted and I lost all my saves, achievements etc. It would be nice to use a backup card on my CPU!
