Vantage PCMark 8 - Storage Test:

PCMark 8 is a complete benchmark for Windows. It includes five benchmark tests, each designed around a specific scenario. The storage benchmark measures drive performance using real-world traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games.

PCMark 8 also includes a consistency test which measures the performance consistency and degradation tendency of a storage system. The test reports the performance level at the start, the degraded steady-state and the recovered state as well as the number of iterations required to reach them. For this test, we are focusing on the Adobe Photoshop (Heavy) trace and will look at both the bandwidth and latency of the drive

The 870 QVO's performance was hit and miss in this test. During the degradation and steady phases, the drive's bandwidth dropped below 100 MB/s, pushing its latency well above the 400ms mark. The 870 QVO recovered quickly though, topping out at about 232 MB/s.
