SD memory cards are a user-exchangeable form of non-volatile digital storage. They're 24mm by 32mm and 2.1mm thick. They all have nine-pin interfaces, a write-protect switch, and operate at 2.7 to 3.6 volts. UHS-II and UHS-III cards have slightly different specs. The latter features a second row of pin interfaces.
Secure Digital
Secure Digital (SD) memory cards are a type of flash memory cards that are used in portable devices. They were developed by Panasonic, Toshiba, and SanDisk as an upgrade to MultiMediaCard (MMC). They also offer high memory density and digital rights management. The logo of SD cards resembles an optical disc. This means that they are compatible with the majority of portable electronic devices. Unlike MMC cards, SD memory cards are not rewritable.

Data transfer rate
The data transfer rate of SD memory cards depends on the device that is using it. This is measured in megabytes per second. SD memory cards other than SDIO have a clock rate of 25 MHz. The speed of the card depends on the operating system and device. It is possible to set the maximum speed by commanding the host device. However, it is not necessary to use the maximum speed of the card. The host device may use a lower clock rate to save power or it may completely stop the clock in between commands.
Write-protection notch
To prevent unauthorized access to your SD card, first make sure that it is physically locked. The lock button will be a plastic slider. Look for the word "lock" on the slider, followed by an arrow pointing down. If the lock is not in place, your PC will not be able to write to the SD card. You should then remove the lock and format the SD card. Then, you can access your data and delete the write-protection notch.
