Ever since Microsoft released the dashboard update for the Xbox 360 that allows it to read and write to USB drives, I’ve been searching for any information on compatible USB sticks storage. The last I read, a list was “forthcoming”.
In addition to that update, Microsoft also announce that they would be selling preconfigured, Xbox branded, USB sticks by Sandisk. In typical Microsoft fashion, they will be overpriced at around $70 for 16GB, and $35 for 8GB. I wouldn’t hold your breath on MS providing a list of compatible USB sticks.
I already tried a 4GB “Energizer” brand that I had lying around on my Xbox and it gave me a warning that it did not pass the performance tests. Despite that, it has been working fine.
I noticed that the part number on the Xbox sticks was similar to Sandisk’s own Cruzer flash drives, so I had a look around for those. I found 16GB Sandisk Cruzer USB sticks at Best Buy for $40 each. It wouldn’t surprise me if they are the exact same drive in different cases. The one linked above on Sandisk’s own page says “new design” but looks pretty much the same as the one at Best Buy.
I ordered a couple and they arrived today. They seem to work great and they pass the Xbox’s performance test.
It should be noted that these drives come with some program installed called U3 Launcher and a hidden partition. If you plan on only using this on your Xbox, it might be worth removing it and freeing up the space. You can find information and a removal tool by searching Google.
