If a user plans on storing video or large photos on their SD Card or microSD card...get at least a Class 6 card...and even better...a Class 10 card. I see those on sale all the time. Shop around, and get a brand name (only) product.
Nope sd cards will not be in the note 6 as it will be slower than the s6 due to ufs I think the reason maybe that people use low class sd cards which degrades. Schematic Micro Sd Card Class 4 Vs Class 6. MicroSD pinout, connector pin out, Signal names and MicroSD Description...
3Samsung 32GB Class10 vs Sandisk 32Gb Ultra class 10 Hi guys!
My recommendation after playing with all sorts of microsd cards and speeds is to get a sandisk 32gb card ( the new sandisk cards do not show a class speed , except for their ultra and extreme cards - This is their new policy ).
The even-numbered class designations for SD and microSD cards, like Class 6 or Class 10, were supposed to provide an easy way to see if a card was fast enough for a particular use. And they did . . . for a while.
