Those who value good quality and speed, can not get at SanDisk. I bought the card as additional storage supplement for my Fuji X100s and the difference to 45MB / s version is noticeably. The images are posted almost twice as fast in RAW format and the import into Lightroom also works much faster than the 45MB / s variant. Whether one that is twice the price value, everyone must decide for himself. Anyway, you can go wrong with buying SanDisk memory cards nothing.
