Kingston DCM1000M Performance Summary: Kingston rates the 3.84TB DC1000M drive we tested for up to 3.1GB/s reads with up to 2.7GB/s writes. Access latency is still low relatively to legacy interfaces / drives, but versus the Samsung and Intel NVMe drives we tested, the DC1000M ends up falling behind a bit. While under load, access latency increases nearly across the board with all drives and at every queue depth, but the Kingston drive's performance took the largest hits overall. A sustained sequential write across the entire volume was initiated, and when performance plateaued, access latency was measured with IOMeter. For this next set of tests, we measured access latency at various queue depths with the same fully random IOmeter 4K access pattern (67% reads, 33% writes), while each of the drives was also under a sustained sequential write workload.
