Samsung EVO Select 512GB
Score: 78/100
SanDisk Extreme PRO 128GB
Score: 84/100Rankings
The SanDisk Extreme PRO 128 GB SDXC offers top-tier read performance and rugged durability, making it ideal for 4K UHD shooting and burst photography. Its write speed is modest for sustained high-bitrate video and it carries a premium price. Best suited for professionals needing reliability and fast off-loads without UHS-II support.
Samsung EVO Select 512GB provides ample high-capacity storage with solid UHS-I performance up to 100 MB/s read and 90 MB/s write, plus robust durability features. However, write speeds can fluctuate and the warranty excludes intensive write-heavy uses. It's a good fit for casual users seeking large capacity at a value price.
