Works

Just tested a drive in question. One thing this does that the same style program on windows doesn’t require, is you have to specify a read/write folder location. PROTIP: Create a new empty folder. Don’t choose your system library or something.

So MUCH better than BlackMagic Disk Speed

Its a Mac port of the loved CystalDiskMark software. I didn't know this was a thing! I'll be singing the praises of it from here on out.
