Reply to Which USB stick and what size? (CDJ)

My 900s arrive today. I have a few old USB sticks lying around, but I figure I should get a decent 3.0 for some faster speeds.

That said, I'm also not sure what size to buy. I'll mainly be bedroom DJ'ing, so I'm not sure that I need to spend a bunch on something too large. How much do I need? I also feel like I read that the Pioneer CDJ's only "officially" support up to 32gig.

Thoughts?
