Samsung EVO Select 512 GB delivers top-tier read speeds, A2 app performance and full 4-proof ruggedness, making it a premium choice for 4K video, gaming and demanding mobile workloads.
The Samsung PRO Ultimate 128 GB SDXC card offers top-tier UHS-I performance (200 MB/s read, 130 MB/s write) together with a rugged build and an included USB 3.0 reader, making it ideal for demanding photography and video workflows.
