According link bellow, SD CARD performance could be optimized if used this software, instead standard OS formatting tool.
However, I wish know what aspects may be affected ( speed access / total size / etc... ) and what is the achieved gain.
"...The SD Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. It is strongly recommended to use the SD Formatter instead of formatting utilities provided with operating systems that format various types of storage media. Using generic formatting utilities may result in less than optimal performance for your memory cards.."
