I know I'm late to the party, but I finally upgraded to a WD, 1TB SSD in my main DJ laptop. I have about 350gigs that had to be transferred. It took about an hour. I left the player running last night in a loop, still working this morning. I was pretty shocked at how fast the box comes up, just crazy. Of those here who have already made the jump, how much did you gain in battery life? Anything? Any pitfalls to watch for?
