MicroSDXC (eXtended Capacity) cards are a type of flash memory card used in various electronic devices, such as smartphones, tablets, cameras, and laptops. They are part of the Secure Digital (SD) family of memory cards, which are known for their compact size and high storage capacity. MicroSDXC cards are an evolution of the MicroSD and MicroSDHC (High Capacity) cards, offering even greater storage capacities.

The "XC" in MicroSDXC stands for eXtended Capacity, indicating that these cards can store up to 2 terabytes (TB) of data. This is significantly higher than the 32 gigabytes (GB) limit of MicroSD cards and the 2 TB limit of MicroSDHC cards. The increased capacity is achieved through the use of a larger address space, allowing for more data to be stored on the card.

MicroSDXC cards use the same physical form factor as MicroSD and MicroSDHC cards, making them compatible with devices that support these earlier formats. However, to take full advantage of the increased capacity, the device must also support the UHS-I (Ultra High Speed Class 1) bus standard, which allows for faster data transfer rates.

In terms of performance, MicroSDXC cards can offer read and write speeds of up to 300 MB/s, depending on the specific card and the device it is used in. This makes them suitable for a wide range of applications, from storing photos and videos to running operating systems on devices like the Raspberry Pi.

When choosing a MicroSDXC card, it is important to consider factors such as storage capacity, speed class, and brand reputation. The speed class rating indicates the minimum write speed of the card, with higher numbers indicating faster write speeds. It is also recommended to choose a card from a reputable brand to ensure reliability and performance.
