Rockbox disk driver speed

test_disk

The plugin we use to measure the disk & disk driver speed and reliability. It is not built by default, so you need to add it (test_disk.c) to your apps/plugins/SOURCES file and rebuild in order to use it.

Speeds

Deactivate dircache during measurement (some of the following results were obtained with dircache enabled). It's recommended to use a "best of three" scheme, i.e. run test_disk three times and take an average of each measurement. The KB/s speeds are given corresponding to the chunk size order: 512/4096/1048576
