Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. AS-SSD Benchmark uses compressed data, so sequential file transfer speeds are reported lower than with other tools using uncompressed data.
AS SSD Benchmark: Intel X99 Platform
Beginning with sequential transfer performance, the 512GB Samsung SSD 950 PRO M.2 solid state drive produced speeds up to 1940 MB/s for reads on the X99 test system, and 1953 MB/s on Z170. Write speeds reached 1433 MB/s on X99, and 1444 MB/s on the Z170 platform.
AS SSD Benchmark: Intel Z170 Platform
Single-threaded 4K IOPS performance tests delivered 32 MB/s reads with 950 PRO on X99, and 44 MB/s reads on Z170. 4K IOPS writes measured 67 MB/s on X99, and a remarkable 167 MB/s on Z170.
64-thread 4K IOPS reads recorded 1125 MB/s on X99 and 1175 on Z170, while write performance reached 361 MB/s on X99 and 374 on the Z170 test system.
In the next section, we continue our testing with Iometer to measure input/output performance…
