Recommended Memory Cards For The Nikon Z5
The Nikon Z5 can take high-end v90 UHS-II memory cards, but users may not see any benefit from spending extra money on these unless they burst and require the 100-shot buffer.
V60 UHS-II cards are a nice compromise; they provide fast transfer speeds with some improvement to write speeds over UHS-I cards, but they also cost a lot less than the UHS-II V90 cards.
UHS-I cards will likely be the best bang for the buck for most casual photographers.
This recommendation list shows how fast each memory card performed in-camera and how each card performed in a USB-C UHS-II reader.
Compare these recommendations to the chart below to find the best memory card for the Nikon Z5 for your shooting style.

In-Camera Memory Card Speeds & Buffer Tests
We tested each memory card in-camera and measured the speed at which the buffer cleared. We do this by calculating the time it took for the buffer to clear after a burst against the written data.
Understand that these are numbers based on the cards I have. Manufacturing and serial numbers are constantly changing with these cards, so use this as a general guide as to how each brand is performing with the camera. Some cameras just work better with the way some brands do their memory card controllers, and this list gives you a general idea of that performance.
Here are the recorded speeds for how each memory card performed in-camera. USB-C read and write speeds are taken from AJA System Test in Windows 11. From this list, you can find the fastest memory card for the Nikon Z5, but it may not be what’s best for what you need since the price and size are always a factor.
Nikon Z 5 Specs
To estimate the buffer size we burst to a very slow card. Raw Shot to fill buffers are taken from the fastest card and are exactly what Nikon reports in their documentation.
Sensor: 24.3MP FX-Format CMOS Sensor Processor: EXPEED 6 Image Processor Continuous Shoot: 4.5fps Est. Buffer Size: 780MB RAW Shots To Fill Buffer: 100 Max Memory Card Size: Unlisted, Likely unlimited. 4k Datarate: 144Mbps |
Best Memory Cards 4k Video
The Nikon Z 5 does 4k at 144Mbps like its big brother and sister, the Z 6 and Z 7. At 144Mbps, we only need a bitrate of 18MB/s.
Typically, when dealing with video, you should buy memory cards with the rated spec that is above your video bitrate.
In other words, U1 cards only guarantee 10MB/s, U3 cards guarantee 30MB/s, v60 cards guarantee 60MB/s, and so on.
With the Nikon Z 5, you will need a minimum of U3 memory cards, so UHS-I U3 cards are fine.
There is one nice UHS-II card that is U3 and made by Sony, the Sony E-card. It has UHS-II read speeds but UHS-I write speeds, and it’s a nice card for a camera like this.
The Lexar Lexar 1667x is also priced very competitively and runs a little faster than the Sony E-card.

Nikon Z5 Record Times – Memory Card Capacity
Here are the record times for 4k bitrates based on a few memory card sizes.
Use this table to see the memory card capacity with different record settings.
We don’t actually know the bitrates of all the different record modes on the Nikon Z5 yet. They haven’t disclosed that information but Nikon has been delivering their 4k 8-bit codecs at 144Mbps.

What Size SD Card Is Best?
If you’re struggling to decide which size memory card to buy and shoot video and stills, you can use the chart above to get an idea of how much time you can get on each card.
For shooting stills, you’ll be able to get through most days with a 64GB card. But if you shoot big events and need thousands of shots or shoot RAW+JPG to a single card, then it might be wise to go with a 128GB card.
I’ve yet to ever fill a 128GB card but I regularly clear off my cards to get everything backed up.
Larger than 128GB cards would be ideal if you plan on shooting for days or weeks without clearing off your cards. This is nice for vacation shooters.
Key Takeaways
There is no doubt that the Nikon Z 5 is an impressive little camera for the price. The dual UHS-II memory card slots offer photographers peace of mind in critical situations.
When trying to decide which speed class to go with, for many, the v90 UHS-II speed class is likely going to be overkill.
Stick with UHS-II cards only if you want faster transfer speeds from your card to your computer, or look for some nice deals on some of the lower v60 speed class UHS-II cards.
UHS-I cards will be fine for most people with this camera, even when shooting 4k video.
