Awesome! Well, except for mac users ignorant of command line :D Gee, mac is unix, too! On linux my weapon of choice for testing sd cards, sticks (usually contain cards!) and even SSD/NVMe. However, despite constantly showing the speed during tests and at the end, it would be nice if it would show also the speed per each h2w-block: Thus one could see when a device starts throttling. Perhaps in some future version?^^ *pretty-please* Havent seen corrupt cards/stick in years now but speed is more...

Perhaps in some future version?^^ *pretty-please* Havent seen corrupt cards/stick in years now but speed is more and more a serious issue (and false advertising thereof). Until then one can always fall back to gnome disks and benchmark accordingly the whole 100% and get a nice graph, of course...
It says it's available for Mac but this is misleading. You really need to know how to run commands via terminal, and there's no DMG file at all. You need to be quite savvy to run this on your Mac, I was unable to run it at all.
You do not know how to use your computer, just get a smartphone ,maybe ? :s
