Tablet comes in tomorrow, thinking I would need a microSD for the extra space. The HD in the Venue 8 Pro supposedly is only 68 MB/s read and 33 MB/s write. However, I've been thinking about getting the Sandisk Extreme 32GB microSD, which is up to 80/50MB/s read/write speed. Since it's faster than the tablet itself, would the speeds therefore be bottlenecked down to what the tablet can do? And are there any other microSD cards you'd recommend to get the best speed possible?
