I'm looking for a way to test random read and write speeds on a Samsung QVO 870 SSD

Does anyone know of an app that does this.

I know windows users can use Crystal Disk Mark to test random read and write speeds, but I don't want to use that since I have already formatted the drive HFS+ and have stuff on it.

I like AmorphousDiskMark, it is in the Mac App Store.

Blackmagic benchmark
Are you referring to Blackmagic Disk Speed Test? BMDST is good for sequential speeds, but unless the app recently changed, it does not do random read and write speeds.

BMDST is really popular on the forum, but I wished more people would use AmorphousDiskMark as it has additional information.
