The Fujifilm X100VI features a single SD card slot that is UHS-I only. Believe it or not, UHS-I cards are fast enough to support the 6k 200Mbps videos as long as they are rated with the V30 or U3 speed class.
Since Fujifilm moved up to a 40MP sensor, I recommend 128GB cards as a starting point.

Here are the best memory cards for the Fujifilm X100VI.
Top 5 Best SD Cards Fuji X100VI
A few great brands are making UHS-I cards that I trust and recommend after benchmarking cards in cameras for over a decade. These UHS-I cards have the new and faster 160MB-200MB/s read speeds technology.
I’m going to start with the Sony E-cards as my first recommendation. They are technically UHS-II cards but they feature write speeds similar to UHS-I cards with much faster read speeds, this brings the cost down very close to the price of the best UHS-I SD cards but gives you all the benefits of UHS-II when it comes to PC transfer speeds. Of course, if you don’t have a UHS-II reader, don’t bother.
Sony E UHS-II 128GB SD Card
The Sony SF-E Series Is a UHS-II v60 SDXC Memory Card from Sony.
Rated Write Speed: 100MB/s
Rated Read Speed: 270MB/s
Rated Sustain: 60MB/s
Note: SD memory cards have various performance specs that differ depending on the capacity of the memory card. Typically, the cards smaller than 128GB capacity do not perform as well as the 128GB and larger cards, which is another reason to use the 128GB cards or larger for the X100VI.
Getting into the standard UHS-I cards, the Lexar Silver series has the fastest write speed, although the read speed is slightly slower than the Sandisk offerings.
Lexar 1066x Silver UHS-I 128GB SD Card
The Lexar Silver Series 1066x UHS-I SDXC memory card sizes 128GB and higher have a write speed rated at 120MB/s.
Rated Write Speed: 120MB/s
Rated Read Speed: 160MB/s
Rated Sustain: 30MB/s
Sandisk has always made great UHS-I cards; these are great values, but not necessarily the fastest cards, as Lexar has been stealing that crown lately.
Sandisk Extreme Pro UHS-I 128GB SD Card
The Sandisk Extreme Pro UHS-I SDXC Memory Card at 128GB is rated with a 90MB/s write speed. The 256GB and larger cards are rated at 140MB/s.
Rated Write Speed: 90MB/s
Rated Read Speed: 200MB/s
Rated Sustain: 30MB/s
Kingston is another solid brand that makes UHS-I cards. I used to use Kingston in one of my older X100 series cameras.
Kingston CanvasGo! Plus UHS-I 128GB SD Card
Kingston CanvasGo! Plus SDXC UHS-I SD cards 128GB or higher have a rated write speed of 90MB/s and a rated read speed of 170MB/s.
Rated Write Speed: 90MB/s
Rated Read Speed: 170MB/s
Rated Sustain: 30MB/s
Transcend has also been around for a very long time. They are less known for their UHS-I memory cards, but they are always top performers.
Transcend Ultra 340s UHS-I 128GB SD Card
Transcend Ultra 340s UHS-I SDXC SD cards at 128GB or higher have a rated write speed of 90MB/s and a rated read speed of 160MB/s. The lower-capacity cards are slower.
Rated Write Speed: 90MB/s
Rated Read Speed: 170MB/s
Rated Sustain: 30MB/s
All these cards will give you a fairly similar performance to the Fujifilm X100VI, so be sure you buy the best deals and cards that have been getting good ratings. Sometimes, bad batches get out into the public, so if you start seeing a bunch of one-star reviews, avoid that card until the batch clears out.
If you shoot a lot of JPGs, buying the fastest memory card for the Fuji X100VI might not be as important as you’ll hit a processor bottleneck if you get into the Clarity and Grain settings, but these are still great cards.
You also don’t need to worry about an A1 or A2 rating with UHS-I cards for cameras. That rating is only useful for running applications.
Fujifilm X100VI Memory Card Capacity
Fujifilm hasn’t specified the maximum size cards that the X100VI can use. However, their compatibility chart only shows that they are testing SDXC cards between 64GB and 512GB in size.
The hardware in this camera can possibly handle cards up to 1-2TB, and there is no limit, but if you are concerned with compatibility, limit your selection to 512GB cards as a maximum size.
