What is the difference between SDHC SDXC and SDUC?
Today, we’ll go through the latest known SD card standards that are available on the market. We know the SD Association has released the SDHC, SDXC and SDUC variations of the SD (Secure Digital) format in that sequence.
The file system used to store data indicated by the card type determines the memory card‘s capacity. Until far, SDHC cards had capacities ranging from 2GBto 32GB, the SDXC card has a capacity of 64GB to 2TB and SDUC has a capacity of 2TB to 128TB.
That is an incredible amount of storage for a device the size of a fingernail.
All of these cards are often formatted with the exFAT file system, which limits their compatibility with a small number of operating systems.
We’ll go through the differences between SDHC SDXC and SDUC cards in this article.
What Is SDHC?
SDHC (Secure Digital High Capacity) is an SD (Secure Digital) card extension that enhances the storage capacity of memory cards to 32 GB. It’s also known as the regular SD card’s version 2.0.
SDHC cards are NOT backwards compatible with host devices that only accept SD (128MB – 2GB) cards due to the fact that SDHC cards are pre-formatted with the FAT32 file system, whereas SD cards are commonly configured with FAT12, FAT16, or FAT16B.
SDHC compatibility should be included into most readers and host devices developed after 2008.
What Is SDXC?
SDXC (Secure Digital eXtended Capacity) is an SD (Secure Digital) card extension that enhances the storage capacity of memory cards from 64GB to 2TB.
It’s also known as the regular SD card’s version 3.0. They are incompatible with devices that only accept SD cards or those that only support SDHC cards.
SDXC cards are, nevertheless, compatible with the majority of devices manufactured after 2010.
This memory card is most commonly found in cameras that take RAW photos and record in 4K.
What Is SDUC?
SDUC (Secure Digital Ultra Capacity) is an SD (Secure Digital) card extension described in the SD 7.0 specification that enhances the storage capacity of memory cards from 2TB to 128TB.
SDUC memory cards can only be used with SDUC host devices, however SD memory cards, SDHC memory cards, SDXC memory cards, and SDUC memory cards can all be used with SDUC host devices.

|Basis of Comparison||SDHC||SDXC||SDUC|
|Stands for||Secure Digital High Capacity||Secure Digital Extended Capacity||Secure Digital Ultra Capacity|
|Capacity||4GB to 32GB.||64GB to 2TB||2TB to 128TB|
|Built By||SDA(SD Card Association)||SDA(SD Card Association)||SDA(SD Card Association)|
|24 mm × 32 mm × 2.1 mm.||24 mm × 32 mm × 2.1 mm.||24 mm × 32 mm × 2.1 mm.|
|Types||SDHC, mini SDHC, micro SDHC||SDXC, mini SDXC, micro SDXC||SDUC, mini SDUC, micro SDUC|
|Application||Digital camera and MP3 players||Cameras, video recorders, phones, camcorders, readers||Suitable for camera and video lover.|
|Compatibility||A host that supports SDHC also supports SD card but host that does not support SDHC will not support SDHC card.||Compatible with devices that are manufactured after 2010. Incompatible with host that does not support SDXC cards.||SDUC memory cards are compatible with the SDUC host. SD, SDHC, and SDXC cards can be used in the SDUC hosts.|
|Data Transfer Speed||25MBps||Up to 300MBps||985MBps|
In conclusion we can say that newer variations of SD card can store more amount of data with higher speed. Also SD card are backward compatible meaning they can run on previous generation of host such as SD, SDHC, SDXC and SDUC.
