As an example of what is coming, the 512MB Microsoft Memory Unit sells for $30 USD while unlicensed storage devices such as the expandable (up to 16GB) 2GB Datel Memory Unit sells for $40 USD.

"If you’ve moved your profile or saved games onto one to 'back it up,' you’d better move it back onto an authorized Xbox 360 storage device prior to taking the update. If you continue to use an unauthorised memory unit after the update, you will not be able to access your stored profile or saved games," adds Hryb.
