Secure Digital cards including SDHC, SDXC and Micro SD cards come pre-formatted in compliance with SD Memory Card standards. Formatting with Windows, Mac or Linux is not compliant with SD Memory Card standards and may cause a performance decrease.
The solution is to either format the card in a device that complies with SDA standards, such as a camera or phone, or use the SDA format utility located here:

Be aware this is only compatible with the following Windows operating systems. It will not work in a Linux computer, so using a SDA compatible device is preferable.
