I am setting up a ESXi 4.0 server and have decided to use the CD installers ability to install to a USB key. I have a freebie slow 1GB Newegg USB key and a very fast 4GB Patriot Xporter XT Boost USB key. I'd like to use the Patriot somewhere else, but if speed makes a difference, I'll just buy another one.
Does the speed of the USB key make a noticeable difference when running ESXi?
