CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using V3.0.3.
Testing the SSD 860 QVO with CrystalDiskMark, we see that the drive falls just short of the other two 4TB SSD 860 drives we have tested when it comes to reads. When it comes to writes it sits between the 860 EVO and the 860 PRO.
