Friendly interface: The different interfaces are pretty explicit and straightforward to use. Every piece of data is clear, and you can easily find all the additional actions you can perform. In addition, you can choose the interface look among several fun themes.
Export: You can copy the result of the benchmark to the clipboard or save it to a file or as an image.
Programmer-friendly: You can even test drives on different networks by executing CrystalDiskMark by a standard user. That's pretty useful to benchmark your float of drives remotely.

How to use CrystalDiskMark?

Once launched, you will see different dropdown lists at the top of the main window. In that order, select the number of tests to run (1-9, default is 5), the test size, and the drive to test. To start the passes, click on the All button. You will see different rows named SEQ1M Q8T1, SEQ1M Q1T1, RND4K Q32T16, and RND4K Q1T1. SEQ1M Q8T1 is for lots of long sequential operations, SEQ1M Q1T1 is the same with only 1 task on a thread (instead of 8), RND4K Q32T16 performs many random tiny operations, and RND4K Q1T1 is the same but with only one process on one thread (instead of 32 processes on 16 threads).
