The SDHC (Secure Digital High Capacity) card is an improved version of the standard Secure Digital (SD) card format, developed to meet the growing demand for higher storage capacities in portable electronic devices. Introduced in 2006 by the SD Card Association, the SDHC card format addressed the limitations of the original SD card, which had a maximum capacity of 2GB.
One of the main advantages of the SDHC card was its significantly increased storage capacity. While the standard SD card was limited to 2GB, the SDHC format offered capacities ranging from 4GB to 32GB initially, and later expanded to 64GB and 128GB versions. This substantial increase in storage capacity made the SDHC card more suitable for storing larger files, such as high-resolution photos, high-definition videos, and data-intensive applications.
Despite its larger capacity, the SDHC card maintained the same physical form factor as the standard SD card, making it compatible with devices that supported the original SD format. However, due to differences in file systems, older devices designed for standard SD cards might not be able to read SDHC cards. Therefore, it’s essential for users to check their device’s compatibility before using an SDHC card.
The SDHC card employs the FAT32 file system, which allows it to handle larger file sizes compared to the original SD card’s FAT16 file system. Additionally, SDHC cards have improved data transfer rates, ensuring smoother performance during data read and write operations.
To indicate the compatibility and capacities of SDHC cards, manufacturers label them with specific class ratings. These class ratings are represented by a number inside a circle, such as Class 2, 4, 6, and 10. The class rating indicates the minimum sustained write speed in megabytes per second. For example, a Class 10 SDHC card has a minimum write speed of 10 MB/s, making it suitable for recording high-definition videos and capturing rapid burst shots in cameras.
While the SDHC card format provided a significant leap in storage capacity and performance over the original SD card, it was eventually succeeded by the SDXC (Secure Digital eXtended Capacity) card format. SDXC cards offered even larger capacities, reaching up to several terabytes, and adopted the exFAT file system to overcome some limitations of FAT32.
In conclusion, the SDHC (Secure Digital High Capacity) card was a vital milestone in the evolution of memory card technology. Its increased storage capacity and improved data transfer rates catered to the growing demands of data-intensive applications and high-resolution media. Although it has been succeeded by the SDXC format, the SDHC card remains widely used and supported in many devices, ensuring its continued relevance in the world of portable electronic storage.

The SDXC (Secure Digital eXtended Capacity) card is an advanced and high-capacity memory card format that represents a significant leap in the evolution of storage solutions for portable electronic devices. Introduced in 2009 by the SD Card Association, the SDXC card was developed to meet the ever-increasing demand for larger storage capacities and faster data transfer rates.
The SDXC card builds upon the foundation laid by its predecessors, the SD and SDHC cards, while introducing some key advancements. One of the most notable features of the SDXC card is its significantly expanded storage capacity. While the original SD card was limited to 2GB and the SDHC card offered capacities up to 32GB initially (later expanded to 64GB and 128GB versions), the SDXC format pushed the boundaries further, supporting storage capacities ranging from 64GB to several terabytes.
To accommodate these larger capacities, the SDXC card employs the exFAT (Extended File Allocation Table) file system, which provides better performance and efficiency in handling larger files compared to the FAT32 file system used in SDHC cards. The exFAT file system allows the SDXC card to store files larger than 4GB, which is the limitation of FAT32, making it well-suited for high-definition videos, ultra-high-resolution photos, and other data-intensive applications.
In addition to its expanded storage capacity, the SDXC card also boasts improved data transfer rates. With the introduction of UHS-I (Ultra High-Speed) and UHS-II (Ultra High-Speed II) speed classes, SDXC cards offer faster read and write speeds compared to SD and SDHC cards. These higher data transfer rates ensure smoother performance during tasks such as recording 4K videos, capturing rapid burst shots in high-resolution cameras, and transferring large files between devices.
Similar to SDHC cards, SDXC cards come with class ratings, denoted by a number inside a circle, such as Class 10, UHS-I U1, UHS-I U3, UHS-II UHS Speed Class 3 (U3), etc. These class ratings indicate the minimum sustained write speed in megabytes per second. The higher the class rating, the faster the data transfer speed of the card.
Despite its impressive capabilities, it’s essential to check device compatibility before using SDXC cards, as not all older devices support the exFAT file system or the UHS speed classes. However, many modern devices, including digital cameras, camcorders, laptops, and smartphones, are equipped to handle SDXC cards, making them a popular choice for users seeking ample storage and fast performance.
In conclusion, the SDXC (Secure Digital eXtended Capacity) card represents a significant advancement in memory card technology, offering vast storage capacities and improved data transfer rates. Its ability to store large files, such as high-definition videos and ultra-high-resolution photos, has made it an indispensable storage medium for professionals and enthusiasts working with data-intensive applications.
