Fujifilm X-T3 | The Speed Test

There are so many UHS-II memory cards now that all work pretty good, however, the X-T3 does still have some lockup issues like the X-H1 and X-T2 so you will have to be selective in which cards you buy.

Here is the speed chart showing how fast each card performs in the Fuji X-T3. I’ll list my recommended memory cards below.

I also checked for 4k playback and recording performance at H.265 at 400mbps. Only a few cards have flawless performance. A lot of cards will record 4k 400mbps fine, but you can’t play back the video clips in-camera.

Fujifilm X-T3 Best SD Memory Cards

Based on the speed chart, compatibility issues and the memory card performance with video, there are only a few cards left that I recommend. Here is the list.


Fujifilm X-T3 Recommended Memory Cards

I will leave Lexar off the list since the brand was purchased by a Chinese memory company Longsys and it will be a completely different card when they release new versions. Lexar is known for having issues in camera like Prograde.

Fujifilm officially recommends the Extreme Pro UHS-II, the Sony G and the Toshiba cards. I love the Toshiba cards but they are harder to find in the USA but are everywhere in Japan.


Sandisk Extreme Pro 300  64GB

Sandisk Extreme Pro UHS-II Recommended Memory Card

Sandisk memory cards really are the best for Fujifilm cameras now. While Lexar, Delkin and Sony did outperform Sandisk by a few MB/s in this particular test, the speed difference is negligible and the Sandisk Extreme 300 cards are really worth it, especially considering they have a lifetime warranty.

Sony G UHS-II 64GB

Sony G UHS-II Recommended Memory Card

The Sony G UHS-II cards came out early 2017 and are one of my top recommended cards. They work great in most cameras especially Fujifilm cameras and even come with data recovery software you can download. The only down side is they only have a 1-year warranty.




Toshiba Exceria Pro Recommended Memory CardToshiba makes great cards, they’re not that popular in the United States and the 64GB size cards are a little hard to find. If you see these come in stock at a good price or if you need a larger size than 64GB, don’t be afraid to pick some up. Often you can find the 64GB model for a better price than the Sony or Sandisk cards.

Cards To Avoid

Of the list of cards the playback 4k 400mbps, there are a few you should avoid until I can do more testing and learn more information.


Cards to avoid include: Prograde, Lexar, Delkin, Adata.

The fastest Delkin card seems to be performing fine for me, but the slower card has slow initialization issues. Hoodman, Fujifilm, Transcend, I believe they are all the same card with private branding and also work great. I’ve seen only one issue in the past with someone having an issue with a Fujifilm UHS-II card, but I haven’t given them my endurance test yet.

The Adata card just started giving me issues. My camera went into a lockup and my custom settings all got wiped out.

I’ll continue going through all the UHS-II cards to see if I can get them to fail after a lot of shooting.

So far bad cards

Prograde v60 – the slow one – faster version is on the way

Delkin V60 (1900x / Prime) – slow card causes slow initialization

Adata – camera crash, trouble powering lens, custom menu reset.



Fujifilm X-T3 Memory Card Lockup Issues


A lot of people are blaming memory cards for the lockup issues Fujifilm is having. I’ve been testing all the memory cards in Fujifilm cameras for over four years now and have noticed some patterns and behaviors of Fujifilm cameras that I will explain.

Every camera brand has memory card problems, bad memory card performance in the Fujifilm X-T3 isn’t unique to Fujifilm. I’ve received may comments and emails from Sony shooters having compatibility issues with U3 cards, Panasonic cameras have some serious issues especially with Lexar, and memory cards for the GoPro Hero6 and Hero5 especially has very serious problems, which is why I make these pages to help the community.


Types Of Lockups

There are two types of lockups I’ve seen. One happens when the card is trying to initialize, when you first turn on the camera, or if the camera goes into sleep then you try to wake it up. You’ll see the image display but no information comes up, even turning off your camera won’t release you from this crash and you have to eject your battery.

The other lockup happens when shooting Continuous H burst mode where the camera will just freeze. 



Fujifilm X-T3 Best Memory Cards 4k Video


All of the UHS-II cards will let you record 4k 400mbps, even a lot of the UHS-I cards on the top of the chart record 4k 400, but you will be inviting problems if you try to use UHS-I cards.

Also, even though the 4k clips will record, you can only play back the footage in-camera with the fastest UHS-II cards.

400mbps is a massive data stream and you need a card that can produce minimum write speeds of 50MB/s. This means U3 or v30 cards do not qualify and you’ll need V60 cards at least, preferably v90 cards for flawless playback and recording.

I recommend the three cards above as the best memory cards for 4k video in the Fuji X-T3.


ExFat vs Fat 32

Right now Fujifilm cameras only record Fat32, so you will have a 4GB file size limit. At 4K 400mbps that ends up being about 1 minute and 20 seconds. 

The good news is, Fujifilm is working on firmware to give their cameras 64-bit ExFat file system which will eliminate the 4GB file size limit.



Using Dual Memory Card Slots


Backup Mode

If you plan on using both memory card slots you will need to use fast cards in each slot if you plan on shooting in backup mode.

When shooting in backup mode, using a slow card will cripple the whole system to it’s maximum speed. 

Also, if you shoot RAW+JPG, you will not get as good of performance as you will by only shooting RAW.



If you’re shooting with a second card in slot two and you’re only set to overflow, then your performance will only be limited to the speed of the card being used at that time.



Best Memory Cards Fujifilm X-T3 | Bottom Line

The three recommended memory cards by Sony, Sandisk and Toshiba are really the way to go with the Fujifilm X-T3. However, if you’re not planning on using the camera for 4k 400mbps video shooting and you don’t do a lot of burst shooting, you can get away with a Sandisk Extreme Pro or any of the UHS-I cards on the top of the test chart as long as they are not, Lexar or Prograde.
