MediaTester can test any media (SD, microSD, thumb, etc) and verify it stores the expected number of bytes. The testing method is similar to h2testw but MediaTester can detect fake or defective media much faster by performing quick reads as data is written. If you buy any storage media, use MediaTester to verify it or risk losing your data.
