I ran several tests both on my computer, and my phone it wrote at 6MB and read at about 6 to 10 depeneding on its mood. I bought this to replace a generic 32GB class 10 card that I lost (so dang small i droped it and could not find it. that Card actual wrote at 11 to 12MB and read at 20MB. I went with sandisk because my phone came with a class 2 that performs more like a class 6. What a waste of time. Refunded this item
