The Fujifilm X-T3 has had a few upgrades compared to earlier models which have a significant impact on memory card performance, in this guide, I test the most popular UHS-II memory cards in the X-T3 to see which cards perform the best.
If you want to get the best memory card performance with stills and video in the X-T3, there are only a few great cards that I recommend because of the high bit rate 4k video.
Use this guide to find the best memory cards for the Fujifilm X-T3.

Fujifilm X-T3 | The Speed Test
There are so many UHS-II memory cards now that all perform very well. There were some serious lockup issues with early firmware that seems to have been corrected now. So be sure you grab the latest firmware.
Here is the speed chart showing how fast each card performs in the Fuji X-T3. I’ll list my recommended memory cards below as well as more information regarding what ‘No’ means with 4k Vid.

All the UHS-II cards and a lot of the UHS-I cards record 4k 400mbps just fine. I marked the cards no if they gave me other issues, like “read error” when trying to playback the file in-camera.
I know those Sony M cards are loved by many, but they were causing read errors for some reason when playing back the clips. The footage is fine when imported into Premiere. If you don’t care about playing back footage reliably in-camera then the cards marked 4K ‘No’ are fine as long as they aren’t listed as Yes with lockups.
Every camera and every card is different, if it caused issues for me, it might still be ok for you.
There are different types of lockups that I’ll go over later. Sometimes I get initialization issues, sometimes I get whole camera user resets. I test each card while out shooting for my Fuji X lens reviews to see if they give me issues.
*Be sure to grab the latest firmware, it completely fixed my X-T3 from any memory card lockup issues.
Fujifilm X-T3 Best SD Memory Cards
Based on the speed chart, compatibility issues and memory card performance with video, there are only a few cards left that I recommend. Here is the list.
Top 3 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.
Fujifilm officially recommends the Extreme Pro UHS-II, the Sony G, and the Toshiba cards. I love Toshiba cards but they are harder to find in the USA but are everywhere in Japan.
Sandisk Extreme Pro 300 64GB
Available At: Amazon
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. I’m not sure why Sandisk hasn’t taken up the v60 or v90 rating. While this card is still technically only u3, I’ve tested it and have found no problems.
Sony G UHS-II 64GB
Available At: Amazon
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 downside is they only have a 1-year warranty.
The new Sony Tough card is also very good and I highly recommend it.
Available At: Amazon
Toshiba 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.
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 many 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 Hero7 often have problems, which is why I make these pages to help the community.
Types Of Lockups
There are a few 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.
I’ve even had issues where my camera would lock up and my custom user settings would get reset.
These lockups are rare and sometimes I don’t get them for several days.
Cards That Were Causing Lockups
These cards have been showing no issues with the latest firmware.
Prograde v60 – the slow one – v90 version works fine.
Delkin V60 (1900x / Prime) – slow card causes slow initialization
Adata v90 – camera crash, trouble powering lens, custom menu reset.
Transcend UHS-II U3 – Occasional Lockups
Fujifilm UHS-II U3 – Still Testings
Hoodman UHS-II U3 – Still Testing
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.
Even though the 4k clips will record, I’m getting a lot of issues playing back 4k 400mbps footage with a lot of the slower UHS-II cards. I frequently get “Read Errors.”
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.
ExFat vs Fat 32
While the camera still formats the memory cards to ExFat, it doesn’t actually use the 64-bit architecture and the video files are limited to the 4GB 32-bit file size limit. At 4K 400mbps, 4GB clips end up being about 1 minute and 20 seconds.
There was a rumor at fujirumors about the camera getting an exFat support firmware update which will expand the record times.
Fujifilm X-T3 Memory Card Sound Chirping Phenomenon
When recording video with an attached mic you will hear a very quiet chirping or chattering. With some cards, it’s louder than others.
I can only hear beeping when I set my RODE powered external mic to -10dB. With the Sony G card it’s a clear zzeep … zzzeep … zzeep. I also tested a Lexar 1000x with these same conditions and it also produces some similar sound, except this time it was a long quiet hiss for about 20 seconds, then went into the same pulsing pattern.
I tested the Sandisk Extreme Pro 300MB card, and I get hard loud beeps, chirping at the beginning of the clip, then silent, then I hear what sounds like little crickets moving around. chip chip chip … chip chip chip.
To rule out UHS-II being the problem I tested the Sandisk Extreme 170MB/s UHS-I card. I get a pulsing hiss. hisss … hiss …. hiss.
Nobody would probably hear this if they were using a powered mic with +20dB or 0dB, and I don’t hear it with the internal camera mic. But I definitely hear it with -10dB on the RODE mic loud and clear.
If this is a concern of yours, go with the Sandisk UHS-II memory card since it had the most subtle effect for me, and it also seems to work the best for others experiencing this issue as well.
Be sure to test this with your cards and compensate with a powered mic or external recorder if you have to.
Using Dual Memory Card Slots
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 bottleneck the whole system down to the speed of the slowest card.
Also, if you shoot RAW+JPG, you will not get as good of a performance as you do when only shooting RAW. This is because of the extra work the camera has to do when processing the JPG files.
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.
