The Fujifilm X-T3 can take two UHS-II memory cards. The camera performs very well with UHS-II cards so you will see a significant improvement with the V90 cards over the V60 cards. You can set up the camera to run RAW with backup or RAW+JPG backup. If you’re backing up to JPG, you don’t need as fast of a card for slot 2, and I’d run a V90+V60 in that setup.
If you’re shooting video, you do not have the option to run backup, so you can only write to one card at a time. Keep that in mind when buying massive cards; however, with 400Mbps video recording, you can get by with good v60 cards like the Sony M cards.
Memory Card Recommendations For The Fujifilm X-T3
When choosing UHS-II memory cards for the Fujifilm X-T3, there are two different speed classes of cards that will benefit different users. V90 is ideal for shootings that require a lot of bursting and fast speeds.
Video shooters or casual photographers will benefit from V60 cards because of the better price-to-storage ratio. V60 UHS-II cards are more than fast enough for the 4 K video the Fujifilm X-T3 outputs.
Here is a list of the top recommended cards, ranked by In-camera performance and USB read and write speeds.
| Speed Class v90 | In-Camera Speed | USB Write | USB Read | Check Price |
| Sony G Tough Cards | 144.0 MB/s | 229.1 | 270.6 | Amazon |
| Sandisk Extreme Pro 300 | 135.6 MB/s | 242.2 | 293.7 | Amazon |
| ProGrade V90 | 133.6 MB/s | 218.4 | 290.5 | Amazon |

Memory Card Speed Test | In-Camera Test Results
If you don’t like the cards listed above and want to try something else, you can use this chart to compare each card’s performance and price out what you need based on performance.
In-camera speed tests were acquired by measuring the buffer clearing speed, and USB results were taken with Crystal Disk using a USB-C memory card reader.

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 encountering 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 a minimum write speed 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.
Sandisk is still sticking to the U3 rating on their UHS-II cards, but they are still showing more than fast enough results to handle video on the X-T3, and so far, nobody has reported any issues. But theoretically, it is best to stick with the faster speed classes like v60 or v90.
ExFat vs. Fat 32
Fujifilm cameras have been upgraded via firmware to support ExFat files with video. This means you’ll be able to record video clips longer than 4GB if you’re using 64GB or larger memory cards.
If you’re using a 32GB the camera will be forced to use Fat32 and you will have 4GB file size restrictions.
Fujifilm X-T3 Memory Card Sound Chirping Phenomenon
When recording a 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 got hard, loud beeps and chirping at the beginning of the clip, then silent, and then I heard what sounded 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
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 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 would when shooting RAW alone. This is because of the extra work the camera has to do when processing the JPG files.
Overflow
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.
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.

These Angelbird cards are just being released. Not sure what makes them specific for the XT-3 but they’re the v60 verisons. https://www.bhphotovideo.com/c/product/1452854-REG/angelbird_mp_xt3_256sdv60x2_match_pack_for_fujifilm.html
I’ve been testing these in all the newest cameras, the Angel Bird v90 actually ended up being the fastest card in the Olympus EM1X. Their cards have been performing very well and I’ve started recommending them for various cameras.
I think they use similar flash to what Lexar use to use (so Micron), because they have similar issues with the Panasonic GH5 that Lexar had.
As soon as I finish posting the results for the other cameras I’ll test a bunch of the new cards in the X-T3.
I just stumbled upon this post while scouring online for an answer to the “which cheap card will record 4k 10bit?” and I’m feeling a tad discouraged/confused. Technically, if speed were the only factor, any card with V60 would be able to handle it right? So, there are some weird compatibility problems with some cards. When you had with the Delikin V60 and the ProMaster v60 cards, what kind of issues were they and are they still issues with firmware 3.0? Is it possible/likely that Fuji worked out some kinks in newer firmware revisions and just filed those changes under the vague “Fix of slight defects” section of the release notes? *fingers crossed
I haven’t tested the v60 cards with firmware 3 yet, but there seemed to be an issue with continuous burst using v60 cards. Not so much video, they were not serious issues for the most part, just some freezes when pulling the camera out of sleep, things like that. I did have the Adata card once wipe my user preferences but that’s back when the camera was new so maybe that was some glitch with the internal battery.
I have been shooting with the X-T3 a lot lately though with a Lexar 2000x card and a Delkin v90 card without any issues. I’ll switch them out to those v60 cards that gave me issues and see if I still have problems. Fujifilm has fixed a lot of bugs since firmware v1, things like stuck pixels in the EVF or color glitches. Hopefully they’ve included better compatibility to v60 and v90 cards.
So, I took a chance and purchased a Delkin 256GB V60 and gave it a whir. I didn’t do a full and proper test but I recorded about 17minutes without any issue before I stopped the recording myself. I’m actually only running firmware 2.0 as well. I could have just got lucky with the card.
That’s good to hear! The only issue I ever got with Delkin cards was occasional lockups, usually when the camera came out of sleep.
Will Lexar pro 1000x V60 do the job in 4k 400mb/s ???
I just tested the latest version of the Lexar 1000x by longsys for you. It works great! I tested burst shots, 4k 400mbps with both 10-bit and 8-bit H.265 and H.264.
Thank you Mr. Alik
I can now safely do my purchasing
Hey Alik, nice test! What do you tell me about the LEXAR SDXC 1667x V60 250Mb/s 64GB for 4k DCI / 4k 400mb/s? I’m thinking of getting an XT3.
I actually don’t have that card yet so I just ordered it. All the cards have been working great lately, I think Fujifilm fixed all the issues they were having. I’ve been cycling through the different brands as I shoot and haven’t had a single issue lately.
One thing that has been discovered, If you’re shooting video with a quiet mic, some cards cause a louder chirp, or clicks than others. So try to use a powered mic if you’re going into camera. Lexar cards were actually one of the quieter brands in my last test.
I’ll test this card when it arrives in a day or two. I just tested the Lexar 1000x again to see how it does with 400mbps and it’s working fine so I would think the 1667x would work as well.
Thank you, Alik. Your precise information is very powerful for help us to build a solid budget. I leaving Canon and see in Fujifilm a new work tool. I waiting for your results. Have a nice day!
I tested 400mbps video in the 1667x and it works great. No Issues.
I was thinking about it right now hahaha
Thanks for testing, Fuji really seems to have made some firmware updates that help solve potential problems.
I’m looking for XT3 lenses now (or adapters).
Thank you very much!
No Prob!
Hi Alik. There was a doubt. How this card worked with
4096 x 2160 @ 60p (or 50p) / 200 Mbps H.265?
Let’s find out, one sec. Everything just so happens to be sitting in front of me.
Ok, I let it roll for awhile against my monitor which should max out that bitrate. It’s working fine.
Lots of bad reviews on Amazon though…seems like quality control issues.
Hi Alik. Just bought an x-T3. Splurged, so looking to save some money now. I am thinking of buying a SanDisk 64GB Extreme Pro SDXC UHS-I/U3 V30 Class 10 Memory Card, Speed Up to 170MB/s (SDSDXXY-064G-GN4IN). You have some great experience and was wondering if I should wait and go UHS II? Thanks, Jeff
Go with the UHS-II if you plan on shooting 4k 400Mbps video. UHS-I will be fine for everything else. A lot of people are shooting 200Mbps video on this camera because it gives them 60fps in 4k and 400Mbps can be a little overkill with file sizes.
Thanks Alik. Will a UHS-I do 200Mbps? Most of what I do will be portraits and landscape but want to get into video at an amateur level. Thanks, Jeff
Yes they will. They can sometimes do 400Mbps, but as the cards age they can slow down and UHS-I is just at the limit of 400Mbps performance. The Sandisk Extreme Pro UHS-I might do 400Mbps. Mine actually do but it’s probably better to do 200 just so it doesn’t cut out mid recording from a slow down. Try to still record with the HEVC or H.265 though. You’ll get a lot nicer compression even at 200. Most cameras (Except the Canon EOSR and Panasonic GH5) only record 4k at 100mbps and only H.264, so even at 200mbps with h.265, you’ll completely blowing away the competition with performance.
im using 2 lexar x1677 256gig sd cards with a write speed of 78MB/Sec tested on crystal disk…ill be in the middle of shooting 4k 24fps 200mbit and the camera will just…stop recording 10-15 mins into recording ……go to “storing” then give me a “write error” …sometimes ittl record for the whole 30 mins..sometimes it wont….its driving me crazy, and now i hear that lexar is the worst card you can buy for fuji xt3…..my cards are more than fast enough to record 4k at 400 mbit…so why does it keep stopping and storing and giving me write errors when trying to record only 4k 24fps 200mbit??? both cards do this….and also, why am i having such a hard time to find a 256gig capacity v60 card that has a write speed over 120 that will
work without stopping all the time in the x-t3? i see 64, 128, 32, but those arent nearly big enough…this shouldn’t BE this hard =(
When I tested that Lexar in the X-T3 it had a low 57MB/s and a high of 75MB/s which is pretty extreme. It should be fast enough for 200Mbps though.
I’m seeing a lot more issues from people with Lexar as a brand since Micron sold them off to Longsys. Likely some quality control issues with the flash they are getting. The new Lexar is pretty much ProGrade, some of the same guys that ran Lexar, but even Prograde has issues sometimes with Fujifilm and are usually not the top performers.
Right now I would say the best UHS-II memory cards brands are Sandisk, Sony, Delkin, Toshiba. They are always the top performers and always have the least issues and always seem to work in no mater what camera I test them in.
Look at how much better they run in the Sony A7rIV than everything else: https://alikgriffin.com/best-memory-cards-sony-a7riv/
Look at replacing your cards with a Sandisk Extreme Pro (the 300MB/s), Sony G Tough, or standard G, a Delkin Power, or a Toshiba Exceria the UHS-II. The Sony M should be able to get the job done for 200Mbps video as well and they just released a Tough M now.
In general there is a certain type of flash or memory controller in some cards that some cameras do not like. The Lexar cards won’t even work in some Panasonic cameras and firmware v1.00 of the X-T3 or even X-H1 had so many issues with so many cards.
All the cards still cause audio chirping during writing while recording video so it seems like there is possibly some sort of frequency interference or bad ground going on inside the X-T3. Some of the power is maybe surging and it just causes the data signal to get interrupted. I use to get a lot of lockups and other weird issues. Since they released a firmware fixing early 2019, I’ve noticed all the cards run a little slower, so likely they’re throttling some things to alleviate this issue. Totally just my guess.
I’m going to retest everything one more time, hopefully soon. I didn’t post the data from my last retest because it came in so much slower and I only tested my new cards. So I need to restest everything to get a good comparison.
Also, it’s hard to find these issues because not everyone has the same problems. Since cameras source different little chips from different factories during different product runs, it could be some chips they’re getting from Tawian, or where ever, just aren’t performing well. So some people have a perfect camera and some people have a camera with little bugs. The X-H1 was really bad with this. There was a product run of the camera that just had so many lockup issues no matter what you did. You had to use the perfect battery with the perfect cards.
One last thing, try using your official fujifilm battery when recording video instead of anything third-party. Sometimes that helps.
Hi Alik, greetings from Mexico, I recently purchased a X-T3, specially for video, I would like to shoot in 4K 60fps 10bit 4:2:0 and I’m looking for an SD card to handle that, I saw the Adata V90 256gb in a good price (around $120 dollars) but I saw many bad comments about this memory, so I’m able to buy the Lexar X2000 (128gb) or the Sony G (64gb) but they are more expensive, so, could you please help me? Adata is really that bad? Which one should I buy? Thanks a lot.
I had lockups with the Adata card with XT3 firmware 1.0. But I haven’t had issues since. I just recorded the spec you mentioned for the duration of a 64GB card to see if there was any issues and everything was fine.
I would take Adata over Lexar right now since I’ve been seeing a lot of people having issues with Lexar.
If you can, go with Sony G, Delkin Power, Sandisk or Toshiba.
Or, some of the slower UHS-II cards can handle the 400mbps. Look at Sony M, Delkin Prime, even ProGrade v60, but for some reason those slower UHS-II cards make the camera always takes a few extra seconds to boot up as it tries to initialize the card, however recording 400Mbps still works fine. This drives me nuts when trying to shoot street photography though.
$120 for a 256 card seems a little too good to be true. Make sure it’s not counterfeit. Maybe bring your camera to the store and test it at the store. Check for bootup times when the card is in the camera, also you need to max that capacity of that card right when you get it to make sure it’s not counterfeit.
I hope this helps.
Hi, Just got an XT3 to use for video and bought the Lexar 1667 256gb v60 and I couldn’t get 4k 400mbits to work at all. Was just greyed out. I connected the memory card to my computer and ran a speed test and it was peaking at 17mb/s read. I bought it direct from Amazon so didn’t think it would be a fake. Seen the Sony M 256gb card pretty cheap so would this do 4k 24 or 60 at 400mbits?
Hey Matt, You know, I’m not sure what’s going on with those Lexar cards these days. They are not owned by the same company ‘micron’ and it seems their quality may have slipped. It could just be a dead card? Even a counterfeit card should perform better than that. Go with the Sony M cards if you can they can do 400Mbps.
Also, I rewrote the memory card suggestions for the X-Pro3 based on the X-T3 tests, I haven’t updated this article yet but there is some good information there that applies to the X-T3 based on the T3 test results. https://alikgriffin.com/best-memory-cards-fujifilm-x-pro-3/
