Which one should I use?

Hi

I want to test my hdd.

Which one should I use for testing hard drive.

CrystalDiskMark5.2 or anvil's storage utility.

Which is more correct.

most people use cristaldisk mark, use both and compare results

you might find that aida 64 or sandra does a better job, but iirc those are paid testing tools
