Crystal Disk Mark review
Crystal Disk Mark is a freeware program which is used to find your hard drive, solid state drive, universal serial bus (HDD, SSD and USB respectively) speed. I have personally used it and it is maybe the best program you can get to find your hard drives speed. I have used it for USB and made a collection of their speeds using this program. It is not famous, but good enough and totally free with some themes to keep you feel better when you try the speeds out.
The program is compatible with all OS, but you better get the latest edition since later in software usually means better. I have downloaded the latest one and made a simple test from the one I had before. Looks like the speeds where not exact, but with the latest version you will surely get the idea. I downloaded the Shizuku theme to find out what is new in the theme and it looks really nice. You can get the latest version from this link
