One of those functions is performing a read and write speed test. It’s like a Swiss army knife for USB drives because it can do so many different things. RMPrepUSB is a tool we have mentioned several times before. The result will show any recoverable or fatal read and write errors along with the final average speed. Therefore, we’d probably recommend stopping after five minutes or so to get a score. As Flash Drive/Card Tester is a testing tool it will keep going until the entire drive has been tested. The program is able to perform a read test, a destructive write test, or a combined read, write and compare test. It’s the only tool here that specifically needs installation.

Check Flash is portable and also has some command line options in Switches.txt.įlash Drive/Card Tester is more of a tool to check your removable USB flash drives, Compact Flash cards or SD cards etc for read and write errors, but also shows the speed of the drive while it’s being tested. Because all the available space is utilized, this test could take a while on empty larger flash drives.

The file will be limited to 4GB for FAT/FAT32. The “Use temporary file” method is non destructive and will fill all the remaining space on the drive with a temporary file and then perform an error check on it while recording the read and write speeds.

In addition, using the more advanced logical or physical Access types allows flash drive erasing, backup and restore and also partition editing. The main function of Check Flash is to scan a USB flash drive for possible errors, but it also runs a read and write speed test while doing so.
