difference between SDXC and SDUC
What is the difference between SDXC and SDUC? 

Today, we’ll go through the latest known SD card standards that are available on the market. The SD Association has released the 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, SDXC cards had capacities ranging from 64GB to 2TB while the SDUC card has a capacity of 2TB to 128TB.

128 TB is an incredible amount of storage for a device, the size of a fingernail.

SDXC and SDUC 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 difference between SDXC and SDUC cards in this article.

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.

 Newer variations of SD cards are capable of storing more data with higer data transfer rate. SDXC card allows you to store 64GB to 2TB of data while SDUC can store 2TB to 128TB of data.

Both advancements, which are part of the SD 7.0 specification, continue the SD Association’s backward compatibility legacy.
