Benchmark - Winsat

'Winsat'  (open an administrator CMD prompt in any version of Windows Vista and above and run 'winsat disk' command) is an internal benchmark built in to every copy of Windows Vista,7,8 and 10 which Microsoft used to give an index of performance for CPU, Memory, Disk and Graphics hardware components.

Originally, especially with Vista, 7 and 8.0, this tool was run in the background on windows install or if a graphics card/driver was changed and generated a user readable index called the Experience Index which was originally up to a score of 8. These scores were also used internally by windows to adjust certain settings such as Windows Graphical Effects based on the result achieved. For disks, Windows can detect whether SSD or HDD was used, adjust super-fetch and other things. Winsat will clearly show the difference when a RAID array is setup, if that RAID array uses caching or not the result will also be evident plus Winsat reports disk LATENCY including percentile calculations, something other tools do not do. The better the latency, the quicker the drive can fetch data or perform maintenance. Winsat also scales correctly for high speed NVME drives.
