[quote name='Wolfpup']I guess it is possible to install games to a USB drive?
It would be slower than the hard drive, as USB 2.0 is slower than SATA, and flash memory sticks are slower than hard drives. I guess it should be faster than the optical drive...probably...although USB requires the CPU to do a lot more work, so there's at least some chance it could impact game performance (although I'd guess so long as one of the three CPUs has a lot of cycles doing nothing, it could use that for USB access without issues).[/QUOTE]
Not sure why you think USB uses more CPU than any other data transfer method, not true at all. What will make a difference is the quality of the USB drive, you want a highspeed one. When you format the USB stick for use, the xbox will actually complain if the USB is a slower type. I ended up taking one brand back due to that message. The usb does work even when you see the error message, but I assume issues may arise later on.
