With the Sony MRW-S1 Memory Card Reader, UHS-II SD cards like the Sony SF-G series can be read at a faster speed. Super-fast transfer compatibility lets you get the most of your high-speed cards. It also brings out the full performance of UHS-I and non-UHS SD memory cards.
Ideal for high-resolution still and 4K video back-ups from UHS-II SD cards, the MRW-S1 saves transfer time so you can get back to editing fast. The MRW-S1 card reader supports the SuperSpeed USB 3.1 Gen 1 interface to get the most from high-performance SF-G series cards. The result is that copying and backing-up files is far faster than through a conventional SD slot on your PC.
