Test hard drives or SD cards with read and write to find errors"
A review by Flo

There are some factors that determine the quality of storage devices. Some of these factors serve as minimal configuration recommendations for some computer units. Especially the computers that are designated to perform multimedia editing. You might have noticed that the speed of copying content to drives are not the same, that is a typical example write speed which is one of the properties that determine the quality of a drive.

Test read and write speed

You can test the reading speed of a given hard drive, but you can test the write speed too. It is useful for checking the health and capabilities of any storage device. The application can test any type of storage device, be it USB flash drive, memory card, solid state drives, etc. Moreover, the user can expedite the speed of disk check by specifying that the program checks specific sectors or the entire disk.

Test fake sd card

H2testw portable is good to check the health of a local or external storage device, but also to spot fake data for SD cards. You can use it as sd card tester too, for flash drives.

Start the program, then
