SANDISK EXTREME PRO SDHC/SDXC UHS-I
In our synthetic benchmarks, the SanDisk Extreme PRO SDHC/SDXC UHS-I SD card performed the fastest of the lot. In real-world tests, it recorded 4K footage without judder and plays it back swimmingly too. We could nitpick that it was actually the slowest in the RAW+JPEG shooting test, but the fraction of a second differences are mostly imperceptible; the Sony being the only card that broke the four-second mark. However, the SanDisk is also the most affordable. Because of its combination of top-class data transfer rate and value, the SanDisk Extreme PRO is our clear winner.
