Yes, you forked over the extra cash to buy the Xbox 360 with the hard drive ( the real one ). Pretty soon, though, you may find that the spacious 20 GB hard drive is not quite enough for all of your downloading needs, especially since you really only have access to 13 of those GBs. This is where Datel steps in. Plugging right into the 360 s USB 2.0 port and being treated as a flash drive, Datel s 4 GB portable hard drive aims to give your 360 just a little bit more wiggle room. For the industrious, you can modify it to use any USB 2.0 external hard drive. Not too shabby for only $133.
