How to specify disk path for e7db/diskmark app

General Discussion
1

I have the e7db/diskmark app running on my NAS. I was able to run it but did not know how to specify a specific drive. Here is the command that worked but probably tested my HDD and not SSD: docker run -it --rm e7db/diskmark
I want to test my M.2 SSD drive. The app is running on my Raid1 hard drives. This is the command I need to run but need help with the path:
docker run -it --rm -v /path/to/disk:/disk e7db/diskmark
I did try running this:
docker run -it --rm -v /dev/nvme0n1:/disk e7db/diskmark
It error out.
Here is the error I get: Target directory is not writable: disk1

I found the solution. To get the correct drive path, create a folder in lower case with no spaces in the name. Then right click on it and select properties. There you will find the drive path. Note, folder name must be in lower case and have no spaces for it to work in the app. So for my SSD, the command line is:
docker run -it --rm -v /volume2/tmp e7db/diskmark
