What is Micro SD card

A SD card (short for Secure Digital card) is an ultra-small flash memory card designed to provide high-capacity memory in a small size. The Micro SD card developed by SanDisk stands out to be a great choice for people to store favorite photos taken and precious videos recorded with their digital cameras, smart phones and other portable devices.

Now SanDisk Micro SD memory card has been designed to be compatible with not only cameras, but also digital video camcorders, laptops, tablets, audio players and mobile phones with SDHC or SDXC card slots that support SD card format. Usually a Micro SD card should be connected to the computer by putting the SD card into a card reader, but now some new tablets have installed the built-in card reader devices to allow you to plug your SD card into the device directly.

Based on different data transmission speed, the SD card is divided into Class 0, 2, 4, 6, 10 as well as UHS-I and UHS-II. Based on different storage capacity, SanDisk SD card is divided into SD card (<=2GB), SDHC card (2GB – 32GB), and SDXC card (32GB-2TB).
