Question What free software should I use to test the performance of 500 GB SSD

[KCav45]

When partitioning my 500 GB SSD into 2 logical drives a message popped-up telling me to check the dive and see that it is working properly. What free software should I use?

I downloaded and ran HDDScan - no errors found. What else should I do?

Which SSD ? More than likely there would be utility for checking it.
