Today, I have tested the speed of my SD cards together with my Sony A7III. I have tested the Sony SF-G64 300MB in Slot 1 while I have tested the SanDisk Extrem Pro MicroSD 80MB and SanDisk Extrem Pro 32 GB 95MB in Slot 2.
Clearly, the Sony SF-G64 in Slot 1 was the overall winner where formatting the card took just 8 seconds, while the SanDisk Extrem Pro 32 GB 95MB in Slot 2 took 14 seconds and the SanDisk Extrem Pro MicroSD 80MB 22 seconds.
It would be interesting to see how the cards perform with the external Sony MRW-S1 High Speed UHS-II USB 3.0 Memory Card Reader/Writer.
