Method Two:

A simpler approach: for example, testing 8G, you can store music or videos that are over 7G. If everything is read properly, it indicates that the card has sufficient capacity.If it is an expansion card, only the files stored in the front section can be read (the exact size of the expansion will need to be determined), while the files in the back section are damaged and cannot be read.

Warm reminder: Due to significant fluctuations in chip prices, the quotes are for reference only.

TF card (small card), different from SD card (large card), is approximately 1/4 the size of an SD card. It is a small memory card that is currently in use and suitable for devices such as mobile phones, car dashcams, car navigation systems, card-mounted speakers, learning devices, cameras, surveillance cameras, etc. The TF card has the advantages of traditional SD cards; when paired with an SD adapter card sleeve, it can be converted into an SD card and is compatible with devices that use SD cards, meeting SD specification standards.
