Memory cards are an important accessory for cameras, camcorders, and smartphones. They are used so you can store additional data. 

Memory cards come in different forms. The original Secure Digital card, also known as the SD card, was launched in 1999.

However, as time passed, there was a need to store more data. This is why memory cards with better performance and larger storage capacity like the SDHC card were released. 

What Is an SDHC Memory Card?

The SDHC card or the Secure Digital High Capacity card is an upgraded version of the original SD memory card. The SDHC has a storage capacity between 4GB to 32GB. 

Since the SDHC card works differently than the SD memory card, it is not backward compatible. This means that the card does not work well with first-generation devices, including old camcorders, old DSLR cameras, and even old card readers.

The Secure Digital High Capacity card, or SDHC, was released in 2006. Its physical aspects are the same as the SD card, and it also has the same function. 

Just like a regular SD memory card, the SDHC cards are inserted in cameras, smartphones, camcorders, and other devices that require added storage. 

What makes the SD card and the SDHC card different is their storage capacity and compatibility. 

SD cards can work in any device that has an SD slot, while SDHC cards have a larger storage capacity, but they can only work on devices that are compatible with the SDHC standard. 

  • Storage Difference

The SDHC cards are known to be able to store more files than a regular memory card. Both memory cards differ in storage capacity, and it also depends on the model that you choose. 

However, an SD card’s maximum storage capacity is only 2GB, while an SDHC card’s maximum storage capacity is 32GB. 

The 2G storage capacity of an SD card can store up to 30 minutes of high definition 4K videos and up to 770 high-quality photos. 

The 32GB storage capacity of an SDHC card can store up to 19 different high-definition videos that can run up to 3 minutes each, and it can store up to 2,228 high-quality photos. 

  • Compatibility

Both the SDHC cards and the SD cards have the same sizes. All devices that support SDHC cards can also support SD cards. However, not all devices that support SD cards can support SDHC cards. 

For you to know if the device that you want is compatible with SD cards or SDHC cards, you can check for a logo on the package or review the manual that came with the devices. It will show you what type of card you can put in it. 

  • Visual Differences

Both memory cards are available in three different sizes. They are the microSD, the miniSD, and the original size. For you to be able to identify the type of card that you have, you need to review the label or check the packaging. If there is an “HC” label on it, then it means the card is SDHC. 

Most devices and card readers only support one card size, so you will need to use an adapter to expand the size and make other cards fit. You can check the slot size of the device that you have before getting a memory card. 

  • Speed Differences

SDHC cards are equipped with the same speed as regular SD cards. Each of them has a speed class, and Class 10 is the highest. 

The speed classes show the minimum speed that it takes to transfer a file to a device, and it is measured in megabytes per second.
