Best Memory Cards Fujifilm X-S20

The Fujifilm X-S20 has a single SD card slot that will utilize UHS-II V90 cards.

While V90 UHS-II cards are the best SD memory cards for the Fujifilm X-S20, you only need V60 cards to take full advantage of the camera’s features. While V90 cards will give you improved speeds when clearing the buffer (useful when bursting at 20fps since the camera has a small buffer), they won’t be necessary for anything else.

To handle the X-S20’s max 6.2k video bitrate of 360mbps, you’ll need at least a UHS-II V60 card. However, if you shoot video at lower bitrates (anything under 240 Mbps), you could switch to UHS-I cards for significant cost savings.

Recommended Memory Cards Fujifilm X-S20

This chart shows the speed at which each card performs in Fujifilm cameras (tests taken from the Fujifilm X-H2s in this sample). You can compare the card’s and minimum sustained speeds against the camera’s video bitrate.

Here are more details for the top 7 recommended cards for the Fujifilm X-S20.

There are a few great Tough cards on the market now. For example, the Sony Tough and the Lexar ARMOR cards. These cards are great since they are so durable, but there are a few downsides. For one, they are a little thicker than your standard plastic card, so in Fujifilm cameras, where the memory card slot is next to the battery door, they can be a little difficult to remove. You can use these cards, but I wouldn’t recommend them if you regularly remove your card from your camera.

Using Film Simulators

If you’re shooting JPGs with settings like grain and clarity enabled, processing time will be your bottleneck more than card speed. So, having v90 speeds might not be a huge advantage if you’re shooting a lot with highly edited film simulators.

Fujifilm X-S20: What Size Card To Buy?

I’d recommend starting with a 128GB card for photo and video usage. For those focusing more on high-bitrate video, you may want to move up to a 256GB card.

Best SD Cards Fujifilm X-S20 | Conclusions

The Fujifilm X-S20 is a fantastic camera that can deliver outstanding results with the right SD cards. Sony, Lexar, or Delkin all offer dependable 128GB UHS-II SD cards that work seamlessly with the Fuji X-S20.

Remember, the camera will only need faster-than-V60 cards if you want to clear the buffer quickly when bursting. And if you’re shooting film simulators with JPGs, the processor will almost always hold you back more than any card’s speed.

Fujifilm X-S20 Full Benchmark Results

All cards tested directly in the Fujifilm X-S20. Unlike cameras that cap out well below V90 speeds, the X-S20 uses most of what V90 cards offer — giving the top V90 options a real advantage over V60 when clearing the buffer at 20fps.

What the Speed Numbers Mean

The MB/s figure for each card is the sustained write speed measured across the full burst sequence — from the first frame through the last frame written to card after the buffer drains. It captures real-world throughput under actual shooting conditions, not a theoretical transfer rate.

On the X-S20, the gap between V90 and V60 is real: top V90 cards (179–187 MB/s) recover from a burst meaningfully faster than the best V60 options (153–156 MB/s). If you’re shooting long burst sequences and need to be ready again quickly, V90 earns its price on this camera. For video at 360 Mbps (45 MB/s required), any V60 card handles it comfortably. The Sandisk Extreme Pro V90 at 108 MB/s significantly underperforms every other V90 card tested — skip it for this camera.
