I snipped a lot of what you asked.
I know that Win2Go requires a USB 3.0 drive and that there were only 2 such drives that were certified to be good enough to actually work. I would assume that Microsoft has taken care of some of the thrashing and such to reduce wear on the drive. Even so, the average USB drive would still get chewed to bits by running a system off of it. That is why only certain USB drives will be certified.
I also know that the device will use the computer's processors, peripherials, and such, but will not use the hard drive. From a booted Win2Go system, you can see that a harddrive exists on teh main system, but you have absolutely no access to it. There is a bit of an expectation that if you are using Win2Go, then you are likely to be storing all your data in the Cloud.
I made a few comments in my blog post on the topic (link in previous post). I can try to find out more if there is interest.
Brad!
