SDXC Camera Memory Cards

If you happen to own a digital camera, you'll need a camera memory card on which to store your photos. SDXC stands for secure digital extended capacity. A newer generation of previous memory cards, this small piece of plastic can store an incredible amount of photos. It also makes for easy file transfer, allowing you to simply remove the card from your camera once you finish taking photos, and then insert it into your computer. Most laptops have a designated port for SD cards. The files are readily accessible for transfer, download and editing with very short transferring time.

How Many Photos Can I Store On My SDXC Card?

Of all the memory cards available, the SDXC offers the most capacity.

  • Technically, the SDXC can range from 64 GB through to a whopping capacity of 1 TB. Realistically speaking, however, by far the easiest to find are 128 GB to 512 GB camera memory cards.
  • If you are shooting in JPEG format (compressed), a 128 GB card will hold over 91,000 images in a 4MP resolution, or more than 16,000 images at a resolution of 22MP.
  • For those who choose to shoot RAW (uncompressed), the same card size holds 9,000 images at 4MP, or 1,664 at 22MP.

Will My Camera Be Compatible With An SDXC Card?

SDXC cards use a file format called exFAT, which operates differently than earlier generations of memory cards. Because of that, the cards may not work with devices that take only SD or SDHC cards.

  • The majority of devices released after 2010 are SDXC compatible, so you can almost certainly rest assured if you have a newer camera.
  • It's possible to check for compatibility by taking a look for the SDXC logo on the camera with which you wish to use it.
  • If you are planning to insert the card in your laptop, computers from 2008 or earlier are generally not SDXC compatible so you may require a newer model of laptop.

Is the SDXC Card Only For Photos?

Photographers generally use the cards as a photo storage method in cameras, however, they are capable of taking video also.

  • Video recording requires slightly different speeds—whilst a burst speed is important for photography, video requires a sustained speed. There are SDXC cards specifically designed to suit either requirement.
  • If the card speed is too slow, you may end up with a corrupted video or one that is very poor quality, as the camera will have compensated for the lack of speed.

For good quality video, look for an SDXC card with a speed class of 10, and that is also a UHS, or ultra-high-speed rating. For example, an SDXC UHS-1 128 GB memory card is ideal.
