SDHC vs. SDXC: the Definition

Definition of SDHC

SDHC (Secure Digital High Capacity) memory cards are widely used in camcorders and cameras. One of the main reasons for their popularity is their high-capacity storage: while an SD card has only up to 2GB of storage, an SDHC card can have up to 32GB. Of course, the more storage space you have, the more photos and videos you can make, and the less you have to worry about this space running out at the most inconvenient moment. In addition, SDHC cards are compatible with many cameras. Note that, if your device says that it’s compatible with SDHC, you can use either SD or SDHC cards. However, if it only says that it’s compatible with SD, you probably won’t be able to use SDHC.

Definition of SDXC

SDXC (Secure Digital eXtended Capacity) memory cards, also very popular, offer even higher capacity than SDHC: in theory, it can reach 2 Terabytes. One other thing that is worth mentioning is the speed capacity of SDHC cards which is also significantly bigger than the one of an SDXC card: up to 300MBps, compared to 10MBps. So, an owner of an SDXC card can have more and longer high-definition photographs and videos and, due to a greater speed capacity, the camera will record everything more smoothly.

Which memory card should you choose?

The answer is, it all depends on what you will use your camera for. Will you photograph athletic events, when you’ll need to take multiple shots every minute? Or will you photograph still objects, only taking a few pictures per session? You should also ask yourself about how quickly you will be able to transfer the photos from your camera to your computer. If it will take you some time, it’s better to have an SDXC which has more storage space.

At the same time, you should consider that having all of your pictures on a single memory card might be risky. If something happens and the card malfunctions, you risk losing all of your photographs. This is why it might be a good idea to have a few SDHC cards with less storage space.
