At Hardware.Info we test SSDs using four identical systems, consisting of an Intel Core i5 7400 (Kaby Lake) processor, an MSI H270 Gaming M3 motherboard and 8 GB DDR4-2400 memory. For the operating system we use Windows 10 Fall Creators Update (version 1709) and the used driver is the Intel Rapid Storage Technologies (RST) driver version 188.8.131.520. We also make sure there is enough airflow in order to prevent any trottling.
First of all we perform some synthetic benchmarks (AS SSD and Atto Disk Benchmark) to find the specific performance characteristics of the SSDs. More important are the real world benchmarks, based on the storage drive usage of real applications. For this we use diverse storage-benchmarks as part of PCMark 8, as well as three workloads that we designed ourselves. With the help of the PCMark8 test we also determine the performance of drives after prolonged periods of heavy load. Based on the different real world benchmarks we determine the Hardware.Info SSD Performance Score 2018 and the Hardware.Info SSD Entry Performance Score 2018; these show the average performance level in a single number.
Aside from performance we also measure the power consumption, both in idle as well as under load
The graphs show the Toshiba XG6 SSD as red bars. For comparison purposes, we have included other current NVMe SSDs in the graphs, where possible in a comparable capacity.
