Intel SSD 750 Series PCIe SSD Review: NVMe For Desktop Performance
In the following tables, we're showing two sets of access patterns; our custom Workstation pattern, with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and a 4K access pattern with a 4K transfer size, comprised of 67% reads (34% writes) and 100% random access.

The first thing to note here is that Iometer is a tricky beast and the numbers are relative only to the precise test condition and workload you're running. We picked these patterns as a rough swag at common end user workloads for workstation or desktop environments, but by no means should they be compared to quoted IOPS throughput that manufacturers use to characterize their drives for the spec sheets. In our "Workstation" test pattern, which is comprised largely of random read requests (80 percent) of small 8K file sizes, we see the SSD 750 shoot way ahead of the pack, even smoking the SSD DC P3700 at either shallow 12 IO queue depths or deep 1152 IO depths (12 worker threads set to 96 IOs each).
In our "Database" access pattern we see the SSD 750 step out strong again but reach a saturation point at deep queue depths for smaller more write-intensive workloads. Here the P3700 just red lines and keeps chewing through requests, no matter how deep the queue depth was. Regardless, the SSD 750 is easily the fastest consumer-targeted SSD we've seen yet in our Iometer testing.
