Score: 75/100
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.
The SanDisk Ultra 64 GB SDXC card delivers solid read performance up to 99.5 MB/s and broad compatibility with major camera brands. Write speeds hover around 16-22 MB/s and it lacks higher video class ratings, limiting 4K use. Suited for casual to semi-professional photographers.
