I bought this card based on your recommendation, received it yesterday. However, in my SP3 in writes max. 20Mb and reads 70Mb. Same speeds with the USB3 adapter. So I returned the card and stick with my Samsung 64Gb pro Microsd card. It is 50% smaller, but writes nearly 70Mb/s (350% faster than the Lexar) and reads nearly 90Mb.The fastest 128GB microSDXC card just got released by Lexar at 95MB/s. Adorama has it for $129.99 with free shipping. This is the card I plan on purchasing since it's made by Micron, which is very good quality in my opinion. Just note that this card is available for pre-order, and should be released in a few more weeks.
