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.
