Fujifilm X100S Memory Card Compatibility

     930 words  5 minutes 
The Fujifilm X100S uses SD, SDHC, & SDXC memory cards. To avoid problems when recording video, cards should be Class 10 with a UHS-I rating.

The Fujifilm X100S may use SD, SDHC, and SDXC memory cards. Fast write speeds are a critical factor for video and continuous shooting.

You can greatly reduce the performance of your camera by using the wrong card.

If you are in a rush, here’s the best SD memory card you can buy for the Fujifilm X100S:

  • UHS-I, U1, and Class 10 Speed Rating. Can sustain 10MB/s write speeds.
  • Excellent choice for photos.
  • Capable of recording Full HD (1920x1080) Video.
  • Inexpensive with more than good enough performance.
  • Larger capacities are available for a reasonable price.

Like all things tech, the price level of memory cards has greatly fallen since the release of the Fujifilm X100S.

With the cost staying quite low, it doesn’t make financial sense to spend money on anything other than a professional-quality memory card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards have all worked well for me. I have under no circumstances had a card failure or data errors with those memory cards.

Every issue I have experienced has been because of cheap unbranded SD cards. Hoping to save around a buck is not worthwhile if your X100S does not function correctly.

If you want to spend less money, buy a lower storage capacity card from a quality company. That way, you will not have to worry about the photographs stored on the SD card.

You are limited to using SD, SDHC, and SDXC cards in the Fujifilm X100S. For best performance, ensure that your camera has the most recent firmware.

The newest cards, SDUC (Secure Digital Ultra Capacity), are not compatible with the X100S.

Four separate types of Secure Digital (SD) cards that you need to pay attention to. They are divided by their size.

  • SD (Secure Digital) - 128MB to 2GB.
  • SDHC (Secure Digital High Capacity) - 4GB to 32GB.
  • SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB.
  • SDUC (Secure Digital Ultra Capacity) - 4TB to 128TB.

Listed below is a fast approximation of the total number of large JPEGs photos you should expect to fit on a memory card:

  • 16GB - 4,640 images
  • 32GB - 9,280 images
  • 64GB - 18,560 images
  • 128GB - 37,120 images

The speed rating of an SD memory card is dependant on the continuous read and write transfer speeds of the card. SD memory card continuous write speed is critical for video in addition to continuous shooting.

A slow SD card can cause a decrease in the number of continuous frames the Fujifilm X100S can take. This is because the camera’s buffer is not able to write data to the memory card quickly enough.

When recording video, a slow SD card can cause a sudden end to shooting. The video file could also end up being corrupted. If you are going to shoot video, it is critical the SD card you use meets the required minimum continuous write speed for video.

Read speed is nice to have for transferring files to a computer or laptop. If you have cards that are full, a card with a fast read speed will save you time.

SD Card Speed Class
SD Card Speed Class

The continuous write speed of a card is represented by the Class rating. SD cards that have a minimum write speed of at least 10MB/s are labeled as Class 10.

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s or faster

Every name-brand SD memory card that you can get online will be rated Class 10. To determine the class rating of a card, look for a number inside of a C on the label.

Example of UHS Rating
Example of UHS Rating

The Ultra High Speed (UHS) bus is often found in SDHC, SDXC, and SDUC cards. UHS allows for faster data transfer rates.

There are three different specs. The three are UHS-I, UHS-II, and UHS-III.

You can determine the rating of a memory card by checking the front of the SD card. A Roman numeral I, II, or III on the label, that is going to be the UHS rating of the memory card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
  • UHS-III - Maximum transfer rate of 624 MB/s

If you found you had to choose one, the 64GB SanDisk Extreme Pro is the best memory card for the Fujifilm X100S. You are now prepared for any future camera you buy.
