Butterfly Read mode is similar to Read mode difference only in blocks' order.

The program tests blocks one by one from minimum to maximum. The program sends the block of data to the drive and the drive writes the block (All previous data in the block on the drive will be overwritten with the pattern and cannot be recovered after that!) The program measures operation time for each block.

In Erase mode the program prepares block of data field with special pattern and an LBA number.

The program reads block of data into a temporary buffer and measures time of operation for each block.

In Read mode device reads block of data and transfers it thorough interface to the host controller.

The program measures operation time for each block.

In Verify mode device reads block of data into drive's internal buffer only and checks for consistency, there is no data transfer through an interface connector/cable.

Verify test may work in unreliable way on USB/Flash devices.
