Understanding the SD Card

How are you doing with your photography!?!  Have you had some beautiful weather to experiment?! I absolutely LOVED your flower photography and plan on featuring some of you real soon!  Today I thought I’d explore ‘Understanding SD Cards’ with you!  They’re so tiny and the writing on them…even tinier…but they’re very important and so I thought it’d be fun to explain their label so that you can double check that you are using the correct card class for your camera…the effect can make a real difference in your photography!

Understanding the SD Card


  • Write Speed – how fast the picture is written to the memory card so you can take your next shot.
  • Read Speed- how fast the photo transfers to the computer when saving.


  • In 2000, the three BIGGEST manufacturers got together and established a SD association that would allow consumers to expect a standard from all SD Cards based on it’s rating:
  • Class 2, Class 4, Class 6 and Class 10, indicated on the front of the card in a three-quarters circle.
  • It’s important to check your manual to determine which is the most compatible with your device.  For example, Class 4 should be capable to provide the necessary speed for all compact camera.  However, if your compact camera offers speed bursts or High Quality video recording, you may need a higher Class SD card.  If the camera recommends a higher class…definitely follow it’s guidance, you won’t regret it.


  • Choose the memory card that works with your device, whether that be SD, SDHC, SDXC, or Compact Flash.


  • If you’re like me and shoot a TON of photos or videos…you’re going to need lots of space for storage!  Higher-capacity cards allow this!  The higher capacity your card is the more memory you’ll have before downloading your photos to your computer.
