In conjunction with a UHS-I compatible device, such as the Nikon D7000, the improved write performance compared to the SDHC Class 10 20MB / s and 30MB / s Edition of Sandisk definitely makes positive impact. While the buffer is full and a file size of 10.5 MB, the continuous shooting speed with the 30MB / s version 1.5 - drops 2 frames per second, it is with the 45 MB / s version with stable 3 frames per second. Positive also be noted that the cards in standard SDHC readers can be read - although there reduced performance compared with UHS-I but it works.
In my view, highly recommended for devices with UHS-I controllers and applications that require the performance. Space upwards is still given enough and so we wait for the first card with 85 MB / s
