With the Fujifilm X70 being the little sister to the X100T, it shares a lot of the same characteristics. The sensor works the same, the speed of the processor is about the same, and even the speed at which it writes to memory cards is very close. The main difference is the X70 is a lot smaller and it has a wider lens.
If you’re looking for the best memory card or you want the fastest memory card for the Fujifilm X70, there are only a few options. Several brands perform wildly different so it’s important to find the best memory card for your camera so you never run into wait times as your buffer clears.
See the performance tests below.

Best Memory Card For The Fujifilm X70
The Fujifilm X70 has only a single UHS-I slot that performs at a top speed of about 42MB/s. Although UHS-II will work, the camera is not designed to take advantage of the UHS-II technology. 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.
Fujifilm X70 Memory Card Speed Tests
These tests are taken out of an average of three, sometimes these cards can perform faster, sometimes slower.
All USB 3.0 tests were done using CyrstalDisk – Windows 10, with the Lexar SR2.

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.

Best UHS-I Memory Cards
UHS-I memory cards are best suited for the X70. The Sandisk Extreme Pro U3 and the Samsung Pro+ U3 memory cards perform the best.

Difference Between U1 and U3 Memory Cards
You might see little symbols on your card saying U1 or U3. This doesn’t necessarily affect 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, then 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.
