Measuring the speed of the system disk.
Comparisons can be made on different devices such as PCs, smartphones, tablets, ChromeBooks, etc.
Continuous writes & reads can be measured fairly close to actual performance, but
Random writes & reads are considerably lower than actual performance due to high browser overhead.
Please treat this as the access speed within HTML5 only.
To measure values close to actual performance, we strongly recommend using Google Chrome.
