This is a micro SD card with a SD adapter included. It was immediately recognized when I popped it into my desktop and laptop. I copied and deleted files. It seemed quick but I don't have a standardized test for these so it is just an impression. Having been around when these were introduced, it is still amazing that you can get 32gb for $18.00. Seems like a great bang for the buck.
