If you are looking for a new storage medium, you will quickly find surprisingly good offers on well known websites. However, these storage media are often devices that offer significantly less storage space than specified by the manufacturer. This is achieved by changing the firmware, which causes the operating system to assume that, for example, two terabytes are available - but in reality only 32 GB can be written. Drive Capacity Tester can verify the manufacturer's specified size of USB sticks and SD cards. Counterfeit storage media can be found quickly. Drive Capacity Tester offers the following features: • Verifying USB sticks USB sticks can be verified. • Verifying SD cards SD cards can also be verified. • Progress indicator The current progress is displayed. There is also a display of the remaining time. • Simultaneous testing Several drives can be verified at once (this function is only available in the Pro version). • Resume a test Is your storage medium very large? Don't want to leave the computer running overnight? No problem! Simply continue the test you have started later (this function is only available in the Pro version). The app icon was designed by Hugo Santos.
