Photographers usually do a lot of research to find the best cameras, tripods, and accessories, but sometimes they don’t think about memory cards. All they know is they want a reliable SD or Compact Flash card that won’t break or go bad over time, and is fast in transferring photos to and from the card.
But it’s useful to have a better understanding the features of memory cards. All cards are labeled with codes that indicate transfer speed, and it’s a good idea to understand these codes. After all, you want to buy a card that’s best suited for your camera (stills and videos) and your type of shooting.
Cris Silvestri’s article identifies these codes and describes their meanings, making it a lot easier for you to buy the right card.
And also do your research on the various brands. Like most other products, memory cards vary from company to company!
