[edit] Features

[edit] Additional Information
Each test can be run with 512 bytes, 4096 bytes, or 16384 bytes per chunk, and in either sequential or random order. The time to read each chunk is displayed in CPU cycles and in microseconds.
If the data read from test_sectors.bin doesn't match the expected data, it will warn you that the driver is malfunctioning.
Because some flash cards have internal blocks larger than the standard ATA 512-byte sector, some chunks may be read more quickly than others, especially sequential reads of 512-byte chunks following the first chunk in a block. For this reason, the tester displays the maximum read time over the last four chunks, as well as the average read time over the whole test.
