Some tests on the other hand – like the read stability test – will keep the existing data structure unharmed. Several different test modes are available including a full erase test. The test length can be selected as well ranging from one full cycle to a manual cycle selection, a burn it mode or until the first error has been found.

The application comes with several command line parameters that can be used to control the application from the command line or batch files. The parameters could be important if the removable drive is not properly identified by the software program. The /all switch will display all drives that are currently connected to the computer system making it easy to pick the removable devices that would not have been found otherwise.

Users should be aware though that the all parameter makes it possible to pick a hard drive for testing as well which can lead to data loss.

Check Flash is an excellent program to test the speeds of USB flashdrives. The program can be directly downloaded from the developers homepage and should run on most Windows operating systems.
