HTML5 Storage Benchmark

HTML5 Storage benchmark

Measure the speed of the system disk.
Comparisons can be made on different devices such as PCs, smartphones, tablets, ChromeBooks, etc.
All processing is completed within the device. No data is sent to the server.

“Consecutive write and read operations can yield measurements that are quite close to actual performance, but…”
“Random write and read operations result in values significantly lower than the actual performance due to the browser's overhead.”
Please treat this as the access speed within HTML5 only.

In order to measure values close to actual performance, we strongly recommend GoogleChrome as the browser used.

If a benchmark is interrupted midway, it leaves behind meaningless data.
