Best Memory Card for Fujifilm X-H2S ?

I have been very satisfied with my transition to Delkin cards for the X-H2S. My personal journey involved testing several brands to find one that could handle the 40fps electronic shutter without lag. I found that the Delkin Devices 128GB POWER CFexpress Type B provides a much more stable experience compared to my older SanDisk cards.

• Focus on the minimum sustained write speed rather than the advertised peak speed.
• Pair your card with a high-quality interface like the ProGrade Digital CFexpress Type B and SD UHS-II Dual-Slot Card Reader to ensure maximum transfer efficiency. It works well for my workflow and I havent run into any of the thermal issues others mention. Definitely a solid path if you want consistent performance.

If you are looking for a CFexpress Type B card, get the Lexar Professional Silver SE CFexpress Type B.

If you are looking for a UHS-II SD card, get the SanDisk Extreme PRO UHS-II V90.

SanDisk CFexpress Type-B and SanDisk V90 SD cards.

Angelbird AV Pro CFexpress Type B card is one of the best choice for X-H2S.

^ This. Also, I would suggest being very cautious about how these cards handle heat during extended recording sessions. I've been thinking about this since I saw your post earlier... in my experience, focusing solely on the maximum speed listed on the label can be a bit misleading. I remember a situation with my first high-speed cards where I didnt account for sustained write performance properly. I was filming a live event and the camera eventually threw a temperature error because the card could not dissipate heat fast enough. It was quite stressful because I had to wait for the hardware to cool down before I could even verify if the footage was saved. Now, I make sure to prioritize reliability and thermal stability over everything else. You might want to consider doing some stress tests at home first just to be safe. It really pays off to be methodical about your storage choices before you are out in the field.
