I was curious to find out just how much faster the new UHS-II SD card is in an Fujifilm X-T1 than an older type card. So I performed a down-and-dirty face off using a stop watch. I set the camera to all manual settings on the ISO, shutter speed, and also set it to manual focus so there would be no delays there, and performed the test shooting in RAW on high speed (8fps), starting the timer the instant the camera speed slowed down and began writing to disc, which was after 22 images.
The results?
My older SanDisk Extreme rated at 80MB/s took 15.46 seconds to write the images to disc. The newer SanDisk Extreme Pro SDHC UHS-II did the same thing in 8:49 seconds - almost twice as fast.
Funny thing is that when transferring the images to my hard drive over a USB 3.0 connection, both SD cards took about the same about of time, 47 sec for the older SD and 43 for the newer UHS-II.
Once the buffer filled in the camera and the card continued to shoot at a slower frame rate, the newer UHS-II card was still twice as fast writing to disc and slowed down to a frame rate at almost 3fps, while the older card slowed to a rate of only 1.4fps.
Admittedly, all this was done with a hand held stop watch and prone to some user error, but after several trials with consistent results, I'm convinced the speed difference is sufficient to justify the newer card.
Yet one more side benefit of the new X-T1 camera!
