I'm going to be purchasing either for the new loader released. I was thinking of going flash drive as the read times are much faster than an external HD's, though you pay much more per gig. Then I thought, would the flash drive choke on the USB 2.0 throughput anyway? It doesn't matter how fast it's being read if it's being transferred at the same USB 2.0 speed that an external HD is loading from. Does anyone know if there would be no difference due to USB 2.0 bandwidth?
