What is Micro SDHC?
The maximum capacity offered by a standard SD card is 2 GB, which is small for data storage and cannot meet big data storage requirements.
Because HD video and images, as well as increment of file sizes, required more storage space, in 2006, a consortium of manufacturers introduced a new SD card standard called Secure Digital High Capacity (SDHC).
MicroSDHC memory card can store data from 4GB to 32GB, similar to that of the standard SD card, but with a much-expanded storage capacity. However, micro SDHC cards work well only with SDHC devices.
Micro SDHC cards are the most reasonable and systematic solution for storage in devices like mobile and cameras which can withstand the toughest climatic and environmental conditions.
With the rising demand for pictures and video-centric mobile apps and social media platforms like Instagram, Facebook, WhatsApp, and Snapchat, the demand for Micro SDHC cards has increased, becoming a standard for quality digital storage.
With online and offline data growing exponentially, the need for storage has become a necessity. It is no more to be called a preference.
These Micro SDHC cards are available in 4 variants, that is with 4 storage capacity sizes, 4GB, 12GB,16GB, and 32 GB.

What is Micro SDXC?
Micro SDXC cards, also known as “Secure Digital Extended Capacity” Cards, are the most feasible and preferred solution for information and data storage in today’s world which is based on SDA 3.0 specifications.
They are a totally new breed of truly high-performance cards with enormous storage capacities, which start from 64GB and range up to 2TB.
The escalating demand for high-quality HD 4K motion pictures, still photos, and the online virtual content material has charged the demand for prolonged and quality storage capacities.
That is wherein the SDXC Cards come into the picture to play an important role. They are specially designed to maximize the overall performance of mobile phones and cameras even in the most challenging environmental conditions.
The intense speeds of the Micro SDXC cards make shifting snapshots and motion pictures among gadgets a breeze, plus a storage capability of as much as 2TB.
However, they are very distinctive from the commonly preferred SD storage cards, using Microsoft’s proprietary report machine (exFAT or Extended File Allocation Table) as the inbuilt default file format.
They are not backwards like-minded with gadgets that handiest take SD storage cards or gadgets that help handiest SDHC playing cards. However, the maximum gadgets which were built post-2010 are highly compatible with SDXC storage cards.
They help to accelerate writing up to 90 MBPS and reading up to almost 100-300 MBPS, which keep an amazing deal of a while shifting high-definition photos and 4K UHD motion pictures.
