The main difference is the X70 is a lot smaller and it has a wider lens.

Best Memory Card For The Fujifilm X70

However with the proper USB 3.0 memory card reader, you can see huge speed improvements when transferring data from your card to your computer.

Recommended SD Memory Cards For The X70

Best UHS-II Memory Cards

The fastest UHS-II memory card for the Fujifilm X70 is the Lexar 2000 UHS-II, In second place is the Toshiba UHS-II.

You don’t need UHS-II memory cards for this camera but if you want one to work along with your XPro2 or XT1 then these have been performing the best. You can also check out how they perform in the X-Pro2 and the XT1.

Difference Between U1 and U3 Memory Cards

You might see little symbols on your card saying U1 or U3. This doesn’t necessarily effect the speed of your card, rather it has to do with the minimum write speed. U3 cards are guaranteed to always perform at a minimum of 30MB/s while U1 cards are only guaranteed to perform at a minimum write speed of 10MB/s. 

Although most modern cards always perform well, when shooting video it’s important to have a card that never drops to a bit rate lower than what the card is capable of writing.

It shouldn’t matter for the Fujifilm X70 which card you use, but some other brands like Sony require U3 memory cards to record 4k Video.


X100T vs X70

Although the X100T and X70 share similar specs, the X100T does write to memory cards slightly faster. The fastest performing card on the X100T was 55.81MB/s while the X70 topped out at 42.93MB/s. I’ll be updating my X100T speeds soon to confirm if the camera is actually faster, or if there were differences in the test controls. I tested the X100T a long time ago now and have changed my lighting setup in these tests since then. 

I have also noticed that processing time and memory card write speeds do slow down when shooting with lower light and at higher ISO. The camera spends more time processing the noisier images. Although with both cameras and with all my tests I always try to adjust the lighting to test with the camera at ISO 1000 to give the camera a nice middle ground to simulated real world shooting conditions.


Best SD Memory Card Fuji X70 Conclusions

While most of the modern SD memory cards perform about the same in the Fujifilm X70, you definitely will see speed improvements with Sandisk and Samsung cards over the other brands if you’re doing a lot of burst photography.

If you don’t do a lot of burst shooting, than most of the popular brands will work fine except Kingston and the Samsung EVO cards. For some reason my Kingston card does not perform well in the X100T either.
