Microsoft Windows 10 vs. Windows 8.1 SSD Storage Performance Analysis

By: Jon Coulter | Editorials in Storage | Posted: Aug 18, 2015 5:10 pm

Moderate Workload Model


We categorize these tests as indicative of a moderate workload environment.



PCMark Vantage - Hard Disk Tests


Version and / or Patch Used:


The reason we like PCMark Vantage is because the recorded traces are played back without system stops. What we see is the raw performance of the drive. This allows us to see a marked difference between scoring that other trace-based benchmarks do not exhibit.


OS Volume 75% Full - Lightly Used







These results are what we would expect to see based on the 4K random performance we saw from our synthetic testing. Windows 8.1 takes the win here, followed once again by Win 10 with RST 13.6 and the Win 10 with RST 14.5.



PCMark 7 - System Storage


Version and / or Patch Used: 1.4.0


We will look to Raw System Storage scoring for an evaluation because it's done without system stops and therefore allows us to see significant scoring differences between drives.


OS Volume 75% Full - Lightly Used






Win 8.1 wins again, but this time Windows 10 with RST 14.5 edges out Win 10 with RST 13.6 for the second best performance.



PCMark 8 - Storage Bandwidth


Version and / or Patch Used: 2.4.304


We use PCMark 8 Storage benchmark to test the performance of SSDs, HDDs, and hybrid drives with traces recorded from Adobe Creative Suite, Microsoft Office, and a selection of popular games. You can test the system drive or any other recognized storage device, including local external drives. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices.


OS Volume 75% Full - Lightly Used






PCMark 8 is the most intensive moderate workload simulation we run. With respect to moderate workloads, this test is what we consider the best indicator of a drive's moderate workload performance. We weren't expecting this; Windows 10 with RST 14.5 significantly outperforms our other two configurations. Now let's see if there is a difference between Win 10 running RST 13.6 and 14.5 on a more mainstream capacity SSD, the highly popular Samsung 850 EVO 500GB.
