Reliable memory card (with a decrease of one month but for now access every day on the data). The card functions as a second drive or a key so I can quietly put over my documents and erase the memory of my 128GB MacBook. the transfer is immediate for standard documents (Word, Excel ...) and as a USB key 3 for videos. All this does not overflow at all on the side so no risk of tearing the map by arranging his camera in his bag and it remains aesthetic. Would recommend for those who have acquired lots of memory and want to optimize their storage. Eventually I certainly take several cards to store my documents if needed (pro, personal, leisure ...). Remove / reset is easy.
