Frequently Asked Questions (FAQ)
What makes a MicroSDHC card different from a MicroSDXC card?
MicroSDHC (High Capacity) cards operate in storage volumes from 4GB up to exactly 32GB using the FAT32 file structure format. MicroSDXC (Extended Capacity) cards start at 64GB and scale up using the exFAT structure. Legacy devices that strictly require the SDHC standard will read this 32GB card perfectly but cannot support larger XC configurations.
Can I capture high-bitrate 4K Ultra-HD video with this card?
This card carries a certified Class 10 standard, ensuring a guaranteed continuous write minimum speed of 10 MB/s. This performance profile is ideal for capturing smooth, uncompressed standard definition and Full HD (1080p) video formats. It is not designed or certified for high-bitrate Ultra-HD 4K video recording pipelines, which generally demand specialized U3 or V30 rated hardware.
Why does my device state that the available space is less than 32GB?
This occurs normally across all digital flash memory lines. Storage card manufacturers calculate capacity boundaries using decimal mathematics, while consumer computer platforms process storage via binary logic. Furthermore, up to 10% of the raw storage capacity is systematically reserved by the card's processing unit for internal file allocation tables, wear-level management, and active system formatting.
