I have the card for memory requirements and speed bought (Continuous Shutter). But also because the transfer annoyed me to the computer in large quantities. Just In: Card does what it should, is felt quickly. And on my new laptop, where the SD / XC slot finally internally depends on the fast bus, I had 8 transmission rates between 90-100 MB / s on the internal SSD in Windows - such figures I have seen with any card previously.
Best value for the price, really :)
Since about 3 weeks in operation, no problems. All good.
