But I’ve yet to have my camera overheat because of this.

When doing these speed tests in my MacBook Pro they would get very hot to touch. The only downside I see to UHS-II is they do get extremely hot. If you only shoot JPEG then speed won’t matter as much since each file is usually only 4-7 megabytes. If you don’t shoot bracketed or burst then it’s less of an issue and your average decently fast card like Samsung or PNY will be fine. This happened to me on the beach once when I use using a card that came in a bundle with the camera.

You’ll need a USB 3.0 UHS-II memory card reader to go with your card. Sandisk 64GB Extreme Pro UHS-II – ( Amazon) Sandisk 32GB Extreme Pro UHS-II – ( Amazon) These are the best-performing memory cards based on my test.

Shooting RAW+JPEG only slows down write speeds of about 3-5 MB/s. I might be able to get that faster a little if I turned noise reduction to -2 but I’m not entirely sure how all that affects speed. JPEG-only write speeds were at around 20-21MB/s no matter what card I used. However, this wasn’t the case with the Lexar 1000x. This tells me that oftentimes the contacts can get dirty or there simply isn’t a great connection. If I take the card out and insert it again the speed will improve. I’m starting to notice sometimes cards will give me slower speeds at random times. Although the Kingston performed slowly on the Fuji X100T.

Of the UHS-I cards, the Sandisk Extreme Pro Class 10 / U3 cards are the fastest. I think it could possibly be a card from a bad production run if such a thing exists. It seemed to perform slower than even some UHS-I cards.

The UHS-II cards perform significantly faster except for the Lexar 1000x. These results can also vary from card to card so your results could be slightly different than mine. Sandisk Extreme Plus 64GB SDXC Class 10 / U3Įxpect the 32GB and 128GB versions of the cards listed above to perform about the same. Sandisk Extreme Pro 64GB SDXC Class 10 / U3 An average of three runs per card were done. The video was recorded with another camera to capture the time it took to clear the buffer, and then the total amount of bytes captured per run was calculated against the time. These tests were done by shooting a burst of RAW images for a dedicated amount of time. The third speed listed is the Fuji X-T1 real-world write speed test. The UHS-II USB 3.0 speeds are done with a UHS-II card reader. The USB 3.0 read/write test is done with the SD card slot in the MacBook Pro. The results are impressive, but not all the UHS-II memory cards will outperform regular UHS-I cards so use this chart to guide you when making a purchase decision. I’ve ordered several of the most popular UHS-II memory cards and have included them in the Fuji X-T1 memory card speed test.

Fujifilm X-T1 is one of the original cameras that can take advantage of the UHS-II memory cards.
