Difference Between Micro SDHC and Micro SDXC

Micro SDHC and Micro SDXC are both types of SD cards with different data transfer speeds and storage capacities.  Micro SDXC cards are considered to be better as they have 13 times more speed than micro SDHC cards, and the performance of the cards depends a lot on their speed.

Micro SDHC vs Micro SDXC 

The main difference between a Micro SDHC card and a Micro SDXC card lies in their storage capacity and data transfer speed. The storage capacity of the Micro SDHC cards starts from 4GB and can be up to 32 GB, while the storage capacity of the Micro SDHC is about 32Gb to 2TB.

SDHC vs SDXC

MicroSDHC is considered second-generation cell phone memory. In 2006, the format was announced, and as a result, a storage device that could meet the endless storage needs of mobile phones appeared. These cards work best when trying to record HD videos. These cards are fast enough to handle large chunks of data but definitely not faster than Micro SDXC cards.

A micro SDXC card is great for those who need more storage space, especially if the amount of data continues to grow. This card is essential for modern smartphones, tablets, drones, and other devices that use micro SD cards. These cards are capable of holding massive storage capacities of data which is considerably more than Micro SDHC cards.

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 the storage requirements of big data. 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, being of a similar size as 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 being 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 card 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 specification. They are a totally new breed of a truly high-performance  cards with enormous storage capacities, which start from 64GB and range up to 2TB. The escalating want of extremely good quality HD 4K motion pictures,  still photos and online virtual content material have charged the demand for prolonged and quality storage capacities. That is wherein the SDXC Cards come to 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 as they use Microsoft’s proprietary report machine called the exFAT or Extended File Allocation Table) as the inbuilt default file format. They are not backward like-minded with gadgets that handiest take SD storage cards or gadgets that help handiest SDHC playing cards. However, 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 that keep an amazing deal of a while at the same time as shifting high-definition photos and 4K UHD motion pictures.

Main Differences Between Micro SDHC and Micro SDXC

  1. Micro SDHC stands for Secure Digital High Capacity, while Micro SDXC stands for Secure Digital Extended Capacity.
  2. Micro SDHC has a storage capacity of 4GB to 32GB, while Micro SDXC offers a storage capacity of a very high range starting from 64GB to 2TB.
  3. The data transfer speed of Micro SDHC is 10 MBPS, while that of Micro SDXC is up to 300MBPS.
  4. Micro SDHC uses FAT32 as its default file format, while SDXC uses exFAT as its default file format.
  5. Micro SDHC cards are compatible with devices that are compatible with Micro SDXC cards. Although, Micro SDXC cards do not work well with old models.

Conclusion

Micro SDHC and Micro SDXC cards are the guidelines for high-capacity advanced media capacity utilized in a broad run of computerized media gadgets such as smartphones, tablets, camcorders, computerized cameras, etc.  They are the most common sorts of memory cards belonging to the SD Card family. Whereas the previous is a progressed form of the standard micro SD Cards with capacity extending from 4GB to 32GB and has a data transfer speed up to 10 MBPS, micro SDXC is a breed of miniaturized scale SD cards based on SDA 3.0 determination with an immensely high storage capacity of up to 2TB and data transfer speed up to 100 MBPS or more.
