Test ends in the middle of the testing area. The first block in the first pair will be Block 0, the second block in the first pair will be Block N (where N is number of last block for testing).

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.
