Planetary Da solemnly promises: All memory cards sold are genuine and of full capacity. We reject expansion cards!!

It is recommended to use the disk software H2testw for detection to reveal the true nature of the expansion card (upgrade card)!

 

Test whether the memory card has sufficient capacity?

Method One

Test using H2testw.

Method Two

A simpler method is to test an 8G card. It can store over 7G of music or videos. If all can be read normally, it indicates that it is a full-capacity card. If it is an expanded card, only the files stored in the front end can be read (the specific size depends on the expansion), while the files in the back end are damaged and cannot be read.

 

 

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

 

The TF card (small card) is different from the SD card (large card). It is about one quarter the size of the SD card and is currently the smallest memory card in circulation. It is suitable for devices such as mobile phones, dash cams, car navigation systems, card-insertion audio systems, learning machines, cameras, and surveillance cameras. TF cards have the advantages of traditional SD cards. When paired with an SD adapter card holder, they can be converted into SD cards and are compatible with devices that use SD cards, meeting the SD specification standards.
