The XBox 360 Memory Unit holds 64mb of memory in a small white unit, probably 2" x 1.5" x .5". This compares to the hard drive that holds 20 gig. This memory unit is meant to be portable - and luckily for gamers, this little memory is WIDELY available so even if you can't find a hard drive for your machine, you should be able to easily find a memory unit.

The nice portability means you can bring the unit along to friends houses to play games that you've partially finished. The unit comes with a solid plastic full-surround case that is relatively sturdy. The case even has a hole cut in one corner, so that you could lock it shut or tie it to your backpack. Of course if someone REALLY wanted to get into the case to steal your memory card, it's not that hard to cut through it with a sharp knife. Still, this should at least deter the casual thief.

The cost for the memory unit is currently $39.99. The memory unit does NOT come with the XBox 360 console so you really need one if not two of them, depending on how much you like to game. In our house we usually like to have at least one memory unit per gamer. That way there aren't any arguments about "You overwrote my game file that I was working on for 1000 hours!!!" It can just take one slip of the finger to lead to sure disaster in the gaming world.

Note that the cards are REALLY easy to use. There are two memory card slots - with built-in covers - right on the front of the XBox 360 console. You simply stick a card into the slot and you're set. The cover automatically folds in when you do that. When you remove the memory unit, the cover automatically slides back into place, to keep dust out of the system.

Highly recommended for every XBox 360 owner!

NOTE: We find that the XBox "System info" that is automatically put on your memory unit cuts down the available memory to 51mb.
