About PCMark 8

PCMark 8 is the latest version in our series of popular PC benchmarking tools. It is designed to test the performance of all types of PC, from tablets to desktops. With five separate benchmark tests plus battery life testing, PCMark 8 helps you find the devices that offer the perfect combination of efficiency and performance. PCMark 8 is the complete PC benchmark for home and business.

PCMark 8 Storage Consistency Test is one of our favorite benchmarks, but also one of the more taxing ones too. Nowadays, many drives are well optimized for high benchmark scores when they are empty, but what separates the professional players from the amateurs is how it stands up to a truly punishing workload. PCMark 8's Storage Consistency Test is designed exactly for this purpose. Going through five phases -- precondition, degradation, steady state, recovery, and clean up -- to extend beyond real world application simulations, this benchmark takes around two days to complete, but the results are revealing of a SSD's true capabilities.

Up to this point, the Western Digital Blue SN550 NVMe SSD 1TB has shown notable improvements from its predecessor as well as the other drives in this price range. However, all of these results were given with the drive being empty, if not near empty. With these tests, we can see what happens to the performance when the drive starts filling up. Interestingly enough, while the previous WD Blue SN500 was relatively stable in each of the degrade, steady, and recovery phases, the SN550 was not as stable, with larger peaks and valleys in each of the stages. The first graph shows the comparison between the original WD Blue NVMe SSD and this one, showing the numbers on average were mostly the same in the degrade and steady phases, while being notably faster in Recovery. Compared to the Crucial P1 1TB, the WD Blue SN550 1TB absolutely smoked the poor performing QLC NAND drive, despite the P1 having onboard DRAM. The final graph shows off the excellent performance of the WD Black SN750, though this is not surprising considering the price gap between the two drives. Even so, I am glad to say the Western Digital Blue SN550 NVMe SSD 1TB still produces good numbers in this test, even if it is a bit less consistent.
