The Samsung Evo Select is a 512GB microSDXC card rated U3 and Class 10, with claimed read speeds up to 100MB/s and writes up to 90MB/s. That makes it a fit for 4K video in phones, drones, action cameras and the Switch, and the bundled full-size SD adapter lets it slot into a laptop or DSLR. It is rated for water, temperature, X-ray, magnetic and shock resistance. Against SanDisk Extreme and Lexar cards it trades peak speed for capacity and price, and it is not the fastest card for sustained burst shooting.
