4. Summary

The Exceria M501 64GB MicroSDXC hit the 210 MB/s and 142 MB/s in the sequential readd and write tests, respectively. The read speed is slower than the 270 MB/s promised by Toshiba, while write was as fast as we expected.

Below you see the performance of the M501 64GB compared to what we measuerd with the Lexar 1800x 64GB UHS-II and the ExceriaPro N101 64GB cards. Generally, the new M501 64GB was a bit slower in the read tests, espacially in the random read tasks.
