If you are looking for a simple, free, reliable tool to measure your stick speed and test its integrity, you can trust Check Flash. This is a simple, portable application that allows us to measure the write and read speed of any USB stick while checking for any problems. To get started, download the program, unzip it and run the application, select your stick and press Start to start the test.
The user can select one of the three types of access types available. Each type of access allows you to perform specific tests and provide useful data. At the end of the test you will see the average write and read speed for your stick and information about any errors found on your disk.
However, prior to testing, it is recommended that your stick is blank and free of data. otherwise, make sure you back up all data contained therein because the device needs to be configured after the test procedure.
