Nikon SD Memory Cards Compatibility

The Nikon D7100 uses SD memory cards. There are two card slots, and you can use one of them or both.

Taking advantage of the dual card slots in the D7100 gives you access to additional memory card management options.

For other information on the camera, check the Nikon D7100 Resources page.

If you are in a hurry and just want the best memory card, my recommendation is:

SanDisk 64GB Extreme PRO SDXC Card

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

Best SD Cards

High quality manufactures of memory cards for the Nikon D7100 include SanDisk, Lexar, and PNY. My favorite brand for SD cards is SanDisk.

I have never had a SanDisk card fail or become corrupted. Lexar Professional and PNY Elite Performance cards have also worked well for me.

The few times I have run into problems with an SD card, was when they were from cheap or generic brands. Trying to save a buck on a cheap card might result in losing all your photos on it in the future. If you want to save money, the best memory card will be a high-quality card, with a smaller capacity.

Nikon D7100 SD Card Compatibility

SDXC, SDHC, and SD cards can be used by the Nikon D7100. Use a UHS-I memory card with UHS-I to get the best overall performance from the camera.

The brand new SDUC memory cards Are not supported by the D7100.

Currently, there are four different types of SD (Secure Digital) memory cards. Newer memory specifications add tech that allows for more memory capacity as well as noticeably increased data 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.

Memory Card Requirements for Video

A class 6 or faster card is needed to record video. Using a slower card will cause problems, such as the recording suddenly stopping.

Most cards that have been produced in the last several years will be class 10 cards.

  • 32GB - 6,400 images
  • 64GB - 12,800 images
  • 128GB - 25,600 images

Speed, Class, & UHS Ratings

SD Card Speed

Speed ratings of an SD memory card is based on the sequential write and read speeds. The transfer speed of an SD card is essential for video as well as continuous shooting.

Slows SD cards can cut down the number of continuous images the Nikon D7100 can take. This is because the camera's buffer is not able to write data to the SD card quickly enough.

When recording video, a slow SD card can cause the recording to end. The video file might also end up being corrupted. If you are going to record video, it is critical the SD card you use meets the minimum requirements of the camera.

Card read speed is nice to have for transferring files to a computer or laptop. If you have cards that are full, an SD card with a fast read speed will decrease the transfer time.

Speed Class Rating

The Class rating of a memory card is related to the sustained write speed. Memory cards that have a minimum write speed of at least 10MB/s will be labeled 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 memory card that you can get online will be rated Class 10. To determine the class rating of a memory card, try to find a number inside of a C on the label.

Ultra High Speed (UHS)

This card has a UHS-I rating. UHS-II and UHS-III cards will have II or III, respectively.

SDXC, SDHC, and SD cards are compatible with the Nikon D800. Use a UHS-I SD memory card with UHS-I to get the best overall performance from the camera.

The latest SDUC memory cards Are not supported by the D800.

Currently, there are four specs of SD (Secure Digital) memory cards. Newer memory specifications add tech that allows for greater storage space as well as greatly improve read/write speeds.
