Review on KODAK 64GB Micro SD Card, High Speed Memory Card, up to 100MB/s Read Speed, 4K Video Recording, Microsdxc UHS-I A1 U3 Class 10 TF Card for Nintendo Switch, Wyze Cam, and Drone by Braden Douville

The card came in bubble wrap which was easy to cut open to remove the card. There is no reading adapter included. The write speed I got was closer to 10MB/s when I ran the test. However, to be completely honest, I didn't have any modern readers (mostly USB 2 holders for a microSD card and were quite old). On the other hand, I reached about 80 MB/s in a short time, I tried another reader. That wasn't during the benchmark, but during "real" data transfer. (I would expect it to be slow in this situation due to the nature of the data being transferred to the SD card). The bottom line, while I didn't have good microSD card readers, my use of the card indicated that the card had the right rating. That said, in the right situations and with the right types of data transfer, read/write speeds can approach 100MB/s, but closer to 10-20MB/s in other situations.
