When you have 60GB to download (as I often do after a day’s shoot), SD card speed is a big deal if I’ve been out hiking all day and want to download and backup and then get to bed.

This is about as fast as this SD card ever reads; the OWC ThunderBay FLEX 8 delivers outstanding read and write speeds for the 128GB Sony SF-G TOUGH card, far faster than the built-in card slot of the 2019 iMac 5K.
