Only stock apps and a few others not can write to the SD card, on my 10.1 (I have two, I can't even put a pdf from dropbox in my pdf folder on my card, I plan to root for the first time once the 8 gets to kitkat, I like how the battery life went way up but the SD card is a big issue.
Though you can always take it out and write via computer, it will read, it just wont write.
PS; On the 10.1 there is already a root program that restores writing to the card but since a few app updates can now write to the card I am waiting a bit on the root. (Pocket Casts now allows writes to the card but only because the android team let them)
