Since I am stuck with an 80GB hard drive for the time being, I can't install the game client to my main drive. I do, however, have a 16 GB flash drive that will do the trick. I was wondering if I would run into technical or performance issues if I install the game to the drive and run it through there. My next drive will be a 64GB SSD to supplement my 80GB HDD. Should I go ahead with the USB drive or wait until the SDD gets here? The SDD won't arrive for several months when my budget allows it.
