My local Staples has the 500 GB FreeAgent GoFlex portable hard drive on sale for 39 bucks this weekend. It is USB 2.0 Does anyone have any experience with this drive hooked up to their S10, or S9 for that matter? Is USB 2.0 fast enough? I know there have been issues with certain HDD's not working well with the Openbox STBs, so I want to make sure I'm not wasting my 39 bucks. Thanks everybody.
