Utilizing the Lexar Multi-Card 2-in-1 USB 3.1 card peruser, I ran three benchmark programs on my 2015 iMac.

I utilized Blackmagic Disk Speed Test, ATTO Disk Benchmark, and DiskMark. 

I additionally ran these equivalent tests utilizing similar benchmark programs utilizing the inherent SD card peruser on my 2015 iMac.
