Random Access Performance

Our first batch of synthetic tests looks at 4K random IO. We test the drive at various queue depths ranging from 1 to 128. Besides random read and random write, we also test a mixed workload that randomly issues a read or write access 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. The weighting factors were chosen accordingly to represent these mostly low queue depth loads.

Sequential Throughput

Next, we test sequential throughput with a large block size of 512 KB. Just like above, a third data point is provided for a mixed workload that randomly issues a read or write access request with equal probability.



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