Storage Speed Test

Measure approximate browser-level disk read and write speeds using IndexedDB.

This test will write and read roughly 25MB of temporary data to your drive.

How it works

This test uses the browser's IndexedDB storage system to read and write temporary blobs of data.

Browser Overhead

Due to browser sandboxing and SQLite abstractions in IndexedDB, these speeds represent what web applications can achieve, but will be noticeably lower than native hardware benchmarks (like CrystalDiskMark).

Testing Tips

Do not perform heavy file copies or installations while running this test to avoid skewed results.
For older hard drives (HDDs), expect speeds under 150 MB/s. Modern NVMe SSDs should score significantly higher.
Running the test multiple times and taking the average provides a more accurate picture of your drive's performance.
