Testing Drive Read/Write Speed Via Terminal

Thu, 23 Nov 2023 00:00:00 -0500

Just a quick example of how to use dd to test drive read/write speed. NOTE: Dont do this a lot or you could shorten the live of your drive since youre making arbitrary writes.

Reading

sudo dd if=/dev/zero of=/tmp/test.img bs=1G count=1 oflag=dsync

This command will write 1G of zeros to an arbitrary file of your choosing. Feel free to delete it when you’re done.

Your output will look a little like this.
