Key Differences
Micro SDHC (Secure Digital High Capacity) Memory Cards are designed to provide storage capacities from 4GB to 32GB. Micro SDXC (Secure Digital eXtended Capacity) Memory Cards, however, offer a significantly higher storage range, starting from 64GB up to 2TB.
The SDHC format, utilized in Micro SDHC cards, is based on the SD 2.0 specification. In contrast, Micro SDXC cards use the newer SD 3.0 specification, allowing for larger storage capacities and faster data transfer speeds.
Micro SDHC cards are widely compatible with many devices but are limited by their maximum capacity of 32GB. Micro SDXC cards provide greater storage solutions but require devices that specifically support the SDXC standard.
In terms of file system, Micro SDHC cards typically use the FAT32 file system. Micro SDXC cards, on the other hand, use the exFAT file system, which supports larger file sizes and is more efficient for larger capacities.
Micro SDHC cards are often used in smartphones, cameras, and tablets for moderate storage needs. Micro SDXC cards are ideal for high-resolution video recording and extensive data storage, such as in 4K video cameras and gaming devices.
