Best Nikon D810A Memory Cards

The Nikon D810A has dual memory card slots, each with its own format. One slot can use SD, SDHC, and SDXC memory cards. The other card slot uses Type 1 Compact Flash memory cards.

In order to get the best results from the D810A it is critical to use an SD card with UHS-I and a Compact Flash card that has a fast write speed.

You will be able to use cards as high as 2TB in size. However, this has not yet been confirmed since there are no 2TB SD or CF cards on the market.

In a hurry? Here's my recommendation for the best Compact Flash and SD memory cards:

SanDisk 64GB Extreme PRO SDXC Card

  • Best value for the money.
  • Transfer speeds up to 170MB/s.
  • Excellent reliability.
  • Temperature-proof, waterproof, shock-proof, and X-ray-proof.

Best CF & SD Cards

SanDisk is the largest brand for both SD and CF memory cards. I have been pleased with all of the SanDisk Extreme Pro SD or CF cards I have used.

Professional grade cards give you the best value. While only a small amount more than inexpensive SD and Compact Flash cards, they will be better built as well as faster.

The only issues I have had with a card was when the card was a generic low-cost memory card. I have never had a card failure or have the data be corrupted when I have used a professional-grade card.

If you are interested in saving money, avoid spending money on a low-cost card. You'll be better off buying s high-quality SD or CF memory card with a lower capacity.

SanDisk 64GB Extreme PRO SDXC Card

  • Best value for the money.
  • Transfer speeds up to 170MB/s.
  • Excellent reliability.
  • Temperature-proof, waterproof, shock-proof, and X-ray-proof.

Nikon D810A SD Card Compatibility

SDXC, SDHC, and SD memory cards can be used by the Nikon D810A. Use a UHS-I SD memory card with UHS-I to get the best performance from the camera.

The brand new SDUC cards cannot be used in the D810A.

There are four different types of SD (Secure Digital) cards. New memory specifications add features that allow for larger memory capacity as well as improved transfer speeds.

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

Nikon D810A CF Card Compatibility

Compact Flash cards as large as 256GB were tested to be operating correctly in a D810A. CF memory cards with a capacity of up to 2TB should work as that would equal the capacity of SDXC cards.

Below is an approximate estimation of how many large JPEG images you can expect to store on each size of SD card.

  • 4GB - 1,160 images
  • 8GB - 2,320 images
  • 16GB - 4,640 images
  • 32GB - 9,280 images

Speed, Class, & UHS Ratings

SD Card Speed

Speed ratings of an SD card is dependant on the sequential read and write speeds. The write speed of a card is important for video as well as continuous shooting.

A slow SD card can cause a reduction in the number of continuous frames the Nikon D810A can take. This is because the buffer in the camera is not able to write data to the card quickly enough.

When recording video, a slow memory card can cause the recording to end. The video file may also be corrupted. If you are going to record video, it is important the memory card you use meets the requirements of the camera.

Card read speed is nice to have for file transfers to a computer or laptop. If you are filling up cards with images or video, a memory card with a fast read speed will save you time.

Speed Class Rating

Example of where to find SD Card Speed Class
10 inside of a C showing that the card is Class 10.

The Class rating of an SD card is determined by the sustained write speed. 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 card that you can get will be rated Class 10. To check the class rating of a card, try to find a number inside of a C on the label.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
This card has a UHS-I rating. UHS-II and UHS-III cards will have II or III, respectively.

The Ultra High Speed (UHS) bus can be found in SDUC, SDXC, and SDHC cards. The UHS bus makes it possible to improve file transfer rates.

Three separate versions exist. They are UHS-I, UHS-II, and UHS-III.

To figure out the rating of a card, look at the label. If the memory card has UHS a Roman numeral I, II, or III will be on the label.

  • 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

Do Both Memory Cards Slots Need to Be Used in the D810A?

No, a single SD or CF memory card will work in the Nikon D810A.

To get more settings, you'll need to use two memory.

You will have access to the following options:

  • Mirror. Both cards will be copies of each other.
  • Overflow. Once the first card is full, images will then be written to the other card.
  • RAW+JPEG. RAW files will be written on one card and Jpeg copies of the images will be written to the second SD or CF memory card.
