The program tests blocks one by one from minimum to maximum. 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.Verify test may have restrictions on Block Size with 256, 16384 or 65536 sectors because of Windows limitations.Author wasn't able to get stable test results with two or more simultaneous tests.

To locate the drivers you want to install for a device, select which of the driver types you wish to use (VCP or D2XX) and then locate the appropriate operating systems. The D2XX driver allows direct access to a USB device via a DLL interface. ![]() The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. Differences in Driver APIįor most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. From revision 2.12.24 with Device Guard Support, the driver will not load on XP or VISTA. NOTE: Microsoft have ended support for certifying XP and VISTA through their WHCK test program.
