What do these storage benchmarks measure?

Jazz Disk Bench measures sequential and 4 KiB random read/write speed. Each entry groups measurements by Model, capacity and platform. The values shown are means; the sample count describes recorded tests, not unique devices.

Open a Model to see every recorded capacity, or compare two configurations side by side. Learn about the tests and units.
