Pentax K110D Memory Card Compatibility

The Pentax K110D uses SD memory cards. 32GB is the maximum capacity SD card that will work in the K110D.

SD memory cards that satisfy the SDUC or SDXC specifications won’t function correctly in the K110D. These cards can simply be avoided as they have a storage capacity of 64GB or larger.

The SDHC format was announced in 2006. All 32GB cards that are currently being produced will have almost identical performance. You cannot go wrong buying the cheapest class 10 name brand card. At the time of writing this, the PNY Elite 32GB SD memory card has the best price.

Here are several possibilities to choose from that will work correctly in the K110D. With all of the cards below, you won’t have to be concerned about card problems or reduced overall performance.

SanDisk, PNY, Samsung, and Lexar both make first-class memory cards. Avoid buying cards from low-priced no-name brands.

Cut-rate cards are more likely to experience file corruption, meaning that you will lose all of your images stored on the card. The decrease in build quality is not worth the minimal savings.

The smart way to reduce expenses is to get a memory card with a smaller capacity. They generally are a bit lower in price and you won’t need to be concerned about the SD card losing your shots.

Keep in mind, SD card issues are rarely experienced. Throughout the years, I have only experienced only two cards fail. Age may have played a role, as the SD cards were included with previously owned DSLRs.

The Pentax K110D can only use SD memory cards. There are four different specifications of Secure Digital (SD) memory cards. The benefit is that there is an increase in the transfer rates and maximum storage capacity with the introduction of each new specification.

Secure Digital memory card readers are backward compatible. A card reader built into a digital camera that can use SDXC cards will also be able to use SDHC and SD memory cards.

The card reader in the Pentax K110D can only read the first and second SD card standards. SDUC or SDXC memory cards will not work.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the K110D.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the K110D.
  • Secure Digital eXtended Capacity (SDXC) - The capacity of these memory cards range from 64GB to 2TiB.
  • Secure Digital Ultra Capacity (SDUC) - The capacity of these memory cards range from 4TiB to 128TiB.

Trying to use a card that has a storage capacity of 64GB or larger in the K110D results in the digital point and shoot camera to display an error.

Use a card with a capacity of 32GB or less to resolve the problem.

If you attempting to use an SD memory card that is 32GB or a smaller capacity, and the card is not functioning correctly, try to format the card while it is in the camera.

The following is a quick estimation of how many large JPEGs you will be able to keep on an SD card.

  • 4GB - 1920 images
  • 8GB - 3840 images
  • 16GB - 7680 images
  • 32GB - 15360 images

The speed rating for SD cards is established by the sequential read and write speeds. The speed of the SD card is important when many pictures need to be written or read from the SD memory card.

SD Card Speed Class
SD Card Speed Class

The Class speed rating of an SD memory card is dependant on the sustained write speed of the memory card. A Class speed rating of 2 means that the SD card can maintain a write speed of a minimum of 2MB per second.

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s

The maximum rating an SD card can have is Class 10. There are SD cards that are substantially faster than 10MB/s. Those SD cards use other technologies, such as UHS (Ultra Highspeed Bus), which use a different rating specifications.

Sustained write speeds of 2MB, 4MB, 6MB, or 8MB per second means the card has a speed class of 2, 4, 6, or 8. Cards that have write speeds of 10MB/s or faster are rated as Class 10.

Buy an SD memory card for the Pentax K110D based on price. An expensive card isn’t going to improve performance. As long as it is a speed class 10 card, you will be fine. My recommendation is the PNY Elite 32GB SD memory card.
