Another great feature of the Sony MRW-G2 is its combo slot, which accepts either a CFexpress Type-A card or an SD card.This was deliberate, as those factors would be difficult to reproduce perfectly for each testing series. CFexpress is now the memory card format of choice for professional cameras , as the best CFexpress cards are significantly faster than even UHS-II SD cards. In our testing, this reader hit a mighty impressive 718MB/s sustained read speed when transferring one large 4K video file.

Its combination of high-speed data transfer rates, lightweight and durable design, and compatibility with both CFexpress Type A and SD cards make it an excellent choice for anyone looking for a reliable and efficient way to transfer data.
