I purchased a Cosair 256gb USB 3.0 Flash Drive. It connects with no issue, but when I tried to run a windows 8 VM (4gb of ram dedicated to the VM), it ran EXTREMELY SLOW.

^^ I'll echo what AtomicGreg stated. First, benchmark the USB3 device using something like Black Magic to get a feel for its performance. Second, test the VM on internal storage.
I don't run VMs from USB3, but I have run one from an SD card with "ok" performance. With that said I'm going to test running a VM from my USB3 flash drive (32 gig Sandisk Extreme) as well as run Black Magic against it. Will report back when done.
I copied 12 gig worth of Ubuntu VM to my flash drive and ran a few things - firefox, software updater (downloaded 114 meg), rebooted etc. It's not as fast as internal storage, but it's not slow either.
