WHY? Why would you do that? What's the point of SSD if you reduce the
speed to USB? Or just use an old mechanical drive instead.  Any issue
with that drive will show up as IO Wait - my presumption is that you
expect to see that so you're not mentioning it but it's going to be
extremely high.

Remember, USB does not behave like SATA. And you may also find that the
"max speed" in the specification is far from what you get out of your
hardware. Use eSATA if you need it externally - not USB(3 or otherwise).
