Score: 100/100
Samsung PRO Plus 1TB
Score: 75/100Rankings
A 512 GB microSDXC U3/V30/A2 card delivering up to 170 MB/s read and 150 MB/s write, rugged durability and high-endurance options, suited for 4K video, Android apps and demanding outdoor use.
The Samsung PRO Plus 1TB microSDXC delivers massive storage and fast UHS-I performance (180 MB/s read, 130 MB/s write) with robust six-layer protection, making it ideal for 4K video, drones and mobile gaming. Its single-year warranty and lack of UHS-II speeds keep it from being the top choice for professional, write-intensive workflows.
