What's the difference between SDHC and micro SDXC?

When you choose to buy a microSD card, you would notice there are usually two kinds of SD card:micro SDXC and SDHC card for your choice. So what is the difference between the microSD formats?SDHC stands for "Secure Digital High Capacity" while SHXC stands for "Secure Digital eXtended Capacity". The difference between these two microSD formats is simply the amount of data they can store. SDHC cards have a capacity of 2GB to 32GB. Alternatively, SDXC cards can range from 32GB to 2TB. In this way, you can distinguish the micro SDXC and SDHC card easily.


What does 'class' mean on a microSD card?

Manufacturers use “speed classes” to measure an SD card’s speed. For micro SDXC and SDHC card, there is no difference in the quality or security or speed. The transfer speed depends on the "CLASS" of the card mentioned on it and not on whether it is a SDHC card or SDXC. The SD Association that defines the SD card standard doesn’t actually define the exact speeds associated with these classes, but they do provide guidelines.

MicroSD card are available in various different speed classes — 10, 6, 4, and 2. 10 is the fastest, while 2 is the slowest. So a Class 2 card reads and writes data at 2 MB/s, while a Class 10 card does so at 10 MB/s. Class 2 is suitable for standard definition video recording, while classes 4 and 6 are suitable for high-definition video recording. Class 10 is suitable for “full HD video recording” and “HD still consecutive recording.”

What does UHS mean on a micro SD card?

UHS stands for Ultra High Speed, and uses a number in the letter U to denote the class. The UHS Speed Classes defined by the SD Association are UHS Speed Class 1 (U1) and UHS Speed Class 3 (U3). A UHS class 1 card writes at a minimum of 10MB/s and a UHS class 3 card writes at a minimum of 30MB/s.
