I can confirm your observations on the thumb drive installations. But
I would lay it more to the poor read/write speed of a standard flash
drive. I intend to pick up a high speed flash drive in a month or two
and try it with that. I would suspect that with a 16 GB high speed
flash drive it should do much better.
