Score: 40/100Rankings
The ProGrade Digital 512 GB UHS-II SDXC V60 card offers solid read/write performance and robust durability for 4K video and fast burst photography, but its speed is modest compared to higher-end UHS-II cards and it requires a compatible host.
The ProGrade Digital Iridium 512 GB SDXC UHS-II V90 card delivers ultra-high read/write speeds and rugged durability for demanding 6K/8K workflows, but its premium price and need for a UHS-II host limit casual use.
