Real world benchmarks
To get a good picture of the performance of SSDs in practice, we run several so-called real world benchmarks, tests that are based on the disk use of real applications.
First of all, the storage test of PCMark8. This benchmark uses so-called traces of Adobe Photoshop, Adobe Illustrator, Adobe Indesign, Adobe After Effects, Microsoft Word, Microsoft Excel, Microsoft PowerPoint, World of Warcraft and Battlefield 3. Scores of all individual tests can be found on the next page.
In the graphs below you will first find the bandwidth score, which is the average read and write throughput rate, measured over all the different test items. Traces are played back in real time, including idle time during the original recording of disk use. The total score is based on the geometric mean time it takes to run all tests, including that idle time. That is why with the standard score the results of all modern SSDs are very close to each other.
The WD Black 2018 NVMe just barely passes the Samsung 970 Evo, but it has to yield to a couple of competitors (including the 970 Pro).

In addition to the PCMark8 real world tests, we also run three in-house developed real world benchmarks. These are traces based on a gaming workload (GTA V and Rise of the Tomb Raider), a light desktop workload (Windows startup, Microsoft Office and Google Chrome) and a heavy desktop workload (Adobe Photoshop and Adobe Lightroom). Whereas PCMark8 disables all operating system-level caches during testing, we leave Windows read and write caches intact for our own real world benchmarks. As a result, these benchmarks may give an even better picture of the performance of discs in practice.
Here, too, the WD Black 2018 NVMe consistently plays a role in the top. In heavy workload, it's even the fastest SSD after the Intel Optane.
