People have reported success with 128GB microSDXC cards, and I suppose the same is the case with 200GB microSDXC cards. Personally and on the SDHC front, I’ve had success with a 64GB microSDHC card.
Do note that, if you use “regular” sized files, you’ll hit the player’s database limit–in that case, you can access all the files through the folder view.
Or, even better, load the alternative firmware Rockbox onto the player–no such database limit.
Lastly, I’ve seen that a Clip just might not work with a particular make of card–I’d always be sure that it is returnable or that I have other uses for it, in that (unlikely) case.
