Test HDD, SSD, and USB Read/Write Speeds with dd
I have found a fancy way to test the speeds of my media devices by using the dd tool. For those that don’t know what the dd command stands for or does, Disk/data Duplicator is a tool that was used in the old BSD/AT&T days but still has great functionality today.
Mostly dd is used for writing a .iso to a USB to be used to boot into a Linux distro or what have you.
