However, there are several options for memory cards and they are divided based on speed, brand, compatibility, and capacity. Even though the SD card is the most used one out of all the memory cards, there are two other formats that are loved by photographers, they are the SDHC and SDXC cards. So which is better between the Micro SDHC vs. SDXC?

Micro SDHC vs SDXC General Overview

The Secure Digital High Capacity cards can store up to 32GB of data, while the Secure Digital Extended Capacity cards have the most storage, with a size of 2 terabytes or 2000GB. Older devices can’t use the SDXC format, make sure that your device supports the larger cards before getting one. 

Micro SDHC

The SDHC memory card is physically and electrically similar to the standard memory cards. However, the SDHC card has the latest technology and it is not compatible with older devices that use the original SD card. 

One of the advantages of SDHC is that it is equipped with a 3 speed class system. This system helps users with transferring their data easily, no matter what the speed is. This means that it can easily meet any performance requirement of your camera. 

Modern cameras use the SDHC card because of its impressive storage capacity. You can store high quality images and high definition videos.

The SDXC has an exFAT system that allows it to handle massive data sizes of volumes that are over 4GB. Also, it has a faster and higher transfer rate than the SDHC thanks to its transfer file of up to 300MBps.

Since the SDHC and SDXC are both SD cards, they have similarities. No matter what the brand of the SDHC and SDXC cards are, the similarities stated below apply to all of them. 

  • Physical: Both the SDHC and the SDXC share the same physical size. They are measured 11 x 15 x 1.0 mm. This is because the devices that are compatible with them only have one slot size, so for you to be able to interchange an SDHC card and an SDXC card, it needs to have a universal physical size. 
  • Shock Proof: Both the SDHC and SDXC cards are shock proof, no matter what brand they are from. This is because it is a standard for all memory cards to have this feature, and it is set by the SD Association Since they are shock proof, your files are safe and the memory card won’t get easily broken if you accidentally drop it. 


Since the SDHC and the SDXC memory cards are released 3 years apart, there are certain improvements that you can find in the SDXC that the SDHC does not have. 

  • Capacity: The SDHC card has a capacity ranging from 4GB to 32GB. Meanwhile the SDXC card has a capacity that ranges from 64GB to 2TB maximum. As more and more people turn to videography, the SD Association decided to launch a memory card that can store thousands of photos and videos without affecting its quality, and that was when the SDXC was released in 2009. 
  • Speed: The speed capacity of a memory card refers to how fast it can transfer the files from the card to the device and vice versa. The SDHC has a speed capacity of 25MB per second, while the SDXC has a speed capacity of 300MB per second. If you wish to be able to transfer more files in a short amount of time, then the SDXC memory card is the one for you.
