Review on 💨 High-Speed SanDisk Extreme PRO SD UHS-II USB-C Reader - SDDR-409-G46: Unleash Lightning-Fast Transfers by Allison Utschig

I tested the SanDisk UHS-II SD card reader on a 2019 16" MacBook Pro and a 2020 11" iPad Pro . In my test, I connect directly to MBP and iPad. As you go through the hub, it slows down. I moved a 2GB file from SD card to iPad Pro and 7 seconds. The card was Sandisk 300MB/sec. I got 220 MB/s with the same card in MBP. It outperformed the Apple SD card adapter by about 10-15 MB/s. So if you're looking for sheer speed and compatibility, buy one or two if you want to read more than 1 card at a time.
