Hey guys, I have latitude 10 (st-2) and wanted to get a SD to get the desperately needed extra space. But I am not sure if SDXC is supported or only sd cards by this tablet. I have researched quite a bit and only seem to find conflicting info. It only says "SD" only on the dummy card in on it and I asked online on Dell chat and they said that I can only use sd cards up to 32gb. Now thats too low! So can anyone comment on this especially if you have same tablet and used sdxc of 64 or 128gb? That will be great. Also I have seen some complaining about not able to read at speeds at more than 25mb/s. Is that true? I would prefer to know limitations before I spend $100 bucks on a card. Thanks in advance!
