“Is there a difference in memory access speed between internal memory and microSD chip access, assuming a class 10 chip? If internal is much faster that could lead me to choose a 64GB Tab S2. Thanks!”

It depends on system bus speed. I read on Android developers forum that all devices read the same speed from storage and internal vs external makes no difference, even in the SD card is a Class 10 card it will only read at the speed of the Bus the device has. The S2 only writes 9mb, then the S2 itself doesn't support the higher speeds. So, no matter ability the card has, if the device's bus doesn't support the higher speed, then the card's ability is meaningless. Any card you use is going to be limited by the bus speed of the device. Paying extra for a better card is pointless if the device doesn't support the higher speed.
Sorry, there was a problem. Please try again later.My tablet is superfast as it is and I did not upgrade to the 64GB --- I do everything on it that I do on my PC - and it's faster.
