While I use a desktop, the files I end up using tend toward the GIG range... a couple are 6.8... not long ago, I added an external HDD... this helps a lot, but even with usb 2.0, it's a little slow... one of the things I learned early is to use purge OFTEN... this helps to keep things moving... ALSO, PS doesn't like to be on the same partition as the OS.... it can cause problems like, "Oops, we have encountered a problem, and must shut down..... have a nice day"... one thing, if you use undo a lot, beware of just how often you purge. Good luck.
