Best Memory Card For The Fujifilm X-T2
The XT2 has two UHS-II slots that can be setup as backup, overflow, or RAW+JPEG.
With the X-T2, UHS-II cards topping out at 157 MB/s, with an average of 153.79. This was with the Lexar 2000x.
UHS-I saw speeds of an average of 73 MB/s.
With a 1GB buffer and memory card speeds like this, we are looking at some really good performance, actually some of the best on the market.
Keep in mind not all cards are created equal, some cards will last longer and have better warranties while often performing slower. You can identify this when you see cards that have ten year warranty vs one or two year. However, many cards offer limited lifetime warranties so you never know how long your card is truly meant to last. That’s why I always just buy the fastest and refresh my cards every few years when prices come down.
These tests are taken out of an average of three, sometimes these cards can perform faster, sometimes slower.

Recommended SD Memory Cards For The X-T2
Best UHS-II Memory Cards
The fastest UHS-II memory card for the X-T2 is the Lexar 2000 UHS-II, In second place is the Toshiba UHS-II.
Transcend is also doing well and Delkin is keeping up.

Using Micro SD Memory Cards
I touch on this subject in the frequently asked question but I wanted to go into a little more detail on my experiences using Micro SD cards since a lot of times they are a less expensive option.
When you use Micro SD cards you have a tiny little card that fits inside an adapter that then fits inside your camera. After using Micro cards for only a few days, I’m already starting to see problems.
With me I’m getting issues with the micro card moves and shifts around in the adapter causes the camera to display Memory Card Errors. You then have to open up the card slot, secure the card and you’re good to go . . . until it happens again.
This won’t happen with every card, and I’m experimenting with different brands, but because it’s happening to me, it means it will happen to other people, so I can’t say I recommend buying micro SD memory cards to save yourself a few dollar. This problem is actually quite annoying.
The other reason I don’t like Micro SD cards is because they are extremely small and easy to lose.
In our cameras we are constantly swapping cards taking them in and out. Micro SD cards are mostly designed for cell phones and other small devices where for the most part they remain in the device permanently. I haven’t lost a card yet, but I could see it being a disaster waiting to happen.
X-T2 Dual Slot Memory Card Configurations
You have a few options for taking advantage of the two UHS-II memory card slots in the X-T2.
Backup: This will mirror the card slot 1 with card slot 2. Keep in mind, when you have this set, you are slowing down your whole system to whatever the slowest card you have is. In other words, the camera can only perform as fast as what’s in slot 2.
Overflow: This is great if you use smaller cards and are worried about running out of space. Once the memory card in slot 1 is full, the camera will start writing to slot 2.
Raw+JPEG: This setting will write RAW to slot 1 and JPEG to slot 2. I haven’t noticed this method slowing down performance of the UHS-II memory card.
Fujifilm X-T2 Frequently Asked Questions
Can I use Micro SD Memory Cards in the Fujifilm X-T2?
Yes you can. There are even UHS-II micro SD memory cards, however, only the newest Micro SD memory cards seem to perform as well as SD cards. I’ve been benchmarking Micro SD memory cards on my GoPro Hero5 memory card page.
I plan on incorporating more Micro SD cards into these tests into the future as I get a lot of people asking me about them.
What Cards Work Best For 4k Video?
This is a huge topic and a very important question. I spend a lot of time testing cards with various cameras on this subject. Especially cameras with high data rate like the Canon 1DX II and the Canon 5D IV. For the Fujifilm X-T2 I’ve yet to really run into problems with cards not working for 4k video. The Fujifilm X-T2 has a data rate of only 100Mbps. While this isn’t terrible data rate to have, it’s also doesn’t pack a whole ton of information and won’t require a very fast card.
100Mb/s (megabits per second) is only 12.5MB/s (Megabytes per second). Based on that alone, almost every card above should work. The only reason they wouldn’t is if you run into maybe some sections in the flash memory that chugs or runs slower. I’ve had some older cards perform very inconsistent with read and write speeds. So just stick with new U3 cards and you’ll never have those problems, as U3 guarantees a minimum of 30MB/s transfer rate.
My Card Isn’t Fast, What’s Wrong?
This is a popular one. Sometimes, some cards are just bad, but there are a few things you can look into.
-You might just have a bad card, send it back. It happens sometimes.
-You could have a fake card! On Amazon and even on Ebay there are a lot of counterfeit cards floating around. It’s sad when I get emails from people who have fallen into this trap. A card will be labeled Sandisk Extreme Pro or something, but it’s actually a crappy old piece of junk. Make sure you always buy your cards from an authorized Amazon dealer, preferably orders that are fulfilled by Amazon themselves, or go with Adorama and B&HPhoto.
-Some cards sometimes perform a little slower until you put a few shots on them. Don’t ask me why, I haven’t been able to figure this out. I get this with some of my Lexar cards and some Transcend cards. Throw a few shots on your card see if that fixes some problems when bursting.
-If your UHS-II card is running really slow, shine a flashlight into your X-T2 and make sure none of the pins are bent. I’ve seen this happen. So be careful when inserting your cards into your camera, never force them.
-Make sure the gold-plated connectors on your memory cards are clean. Every so often when I put a card into the camera doing these tests it will run super slow. I’ll take it out, wipe it down, then everything is fine again. So check your pins on your card and give them a nice wipe down with your shirt or something.
Do I really need a UHS-II memory card?
Honestly, probably not. The Fujifilm X-T2 has a nice 1GB buffer that takes awhile to fill. The UHS-I do run pretty quick as well, some UHS-II cards often don’t even run much faster than UHS-I cards anyway. So unless you do a lot of burst shooting or even a lot of HDR photography where you’re bracketing a lot, you can likely get by just fine with UHS-I.
What Size Memory Card Should I Get – 32GB or 64GB?
Personally, I rarely fill a 32GB card. In my X-T2 I run two 32GB cards, so if I do fill one, it will just overflow to the other card. This almost never happens unless I’m shooting video. So if you do find yourself shooting a lot of video, go with the 64GB cards, otherwise two 32GB has been working great for me.
Best SD Memory Card Fuji X-T2 Conclusions
After finishing the test, I had to double-check my results, I’ve never seen a camera perform this well with SD cards and it surprised me it did so much better than the X-Pro2. This makes the Fujifilm X-T2 one of the fastest cameras at writing to memory cards on the market, completely destroying all of the competition. Aside from the Canon 1DX II with its insanely fast CFast memory cards of course.
To truly maximize the potential of your X-T2 you should stick with the Lexar 2000x or Toshiba UHS-II memory cards. Nothing else compares to the speed you get from these two cards. However, if you just need a card to run in your second slot as a backup or overflow, then a fast UHS-I card may suit your needs just fine.
