Sequential Throughput

Our first batch of synthetic tests looks at sequential throughput with a large block size of 1 MB. We test the drive at various queue depths, ranging from 1 to 128. Besides sequential read and sequential write, we also test a mixed workload that randomly issues a read or write request with equal probability.



To provide some context, the charts below compare these results with other drives. We report a combined and weighted score that should cover real-life consumer workloads very well. Accordingly, the weighting factors were chosen to represent these mostly low queue depth loads (not the absolute maximum possible by the drive, which won't make any difference for real-life usage).

Random Access Performance

Next, we test 4K random IO, which transfers small chunks of data and spreads the accessed areas over the whole workspace of 8 GB. As before, a third data point is provided, for a mixed workload that randomly issues a read or write request with equal probability. Please note that the vertical axis uses non-linear scaling to improve visibility of the low queue depth values—which are more relevant for daily workloads.



Using the same weighted scheme as for sequential IO, the charts below provide comparison data against other drives in the test group.
