Crystal Disk Mark and how it work (question)...

[HORNO]

So, when I run a test on a mechanical hard drive with Crystal Disk Mark, will I get a very different reading on a drive that has more data on it? Lets say I run a test on a 1TB drive and it has 100 GB loaded... will I get a completely different reading if I ran the test on the same exact drive if it had 900 GB loaded?

Was just wondering if the amount of a data on a drive has any impact on the tests.

thanks for any info!
