What are the different types of microSD cards

What are the different types of micro SD cards available in the market?

There are four main types of microSD cards available in the market:

SD or SDSC (Secure Digital Standard Capacity): This is the original type of microSD card. It has a maximum storage capacity of 2 GB.

SDHC (Secure Digital High Capacity): This type of microSD card has a maximum storage capacity of 32 GB. It is backward compatible with SD cards, but it cannot be used in devices that only support SD cards.

SDXC (Secure Digital Extended Capacity): This type of microSD card has a maximum storage capacity of 2 TB. It is backward compatible with SDHC cards, but it cannot be used in devices that only support SD or SDHC cards.

SDUC (Secure Digital Ultra Capacity): This type of microSD card has a maximum storage capacity of 128 TB. It is the newest type of microSD card and is not yet widely supported by devices.

In addition to the four main types of microSD cards, there are also a few other types that are less common:

microSD mini is a smaller version of the microSD card that is no longer widely manufactured.

microSD HC is a type of microSD card that has a storage capacity of 4 GB to 32 GB. It is not widely used anymore and has been replaced by SDHC cards.

MicroSD cards are also classified by their speed. There are three types of speed classes for microSD cards:

Speed Class (Class 2, 4, 6, 10): This speed class indicates the minimum sustained write speed of the microSD card. Class 2 cards have a minimum write speed of 2 MB/s, Class 4 cards have a minimum write speed of 4 MB/s, Class 6 cards have a minimum write speed of 6 MB/s, and Class 10 cards have a minimum write speed of 10 MB/s.

UHS Speed Class (U1, U3): This speed class indicates the minimum sustained write speed of the microSD card in UHS mode. U1 cards have a minimum write speed of 10 MB/s, and U3 cards have a minimum write speed of 30 MB/s.

Video Speed Class (V6, V10, V30, V60, V90): This speed class indicates the minimum sustained write speed of the microSD card for video recording. V6 cards have a minimum write speed of 6 MB/s, V10 cards have a minimum write speed of 10 MB/s, V30 cards have a minimum write speed of 30 MB/s, V60 cards have a minimum write speed of 60 MB/s, and V90 cards have a minimum write speed of 90 MB/s.

When choosing a microSD card, it is important to consider the storage capacity, speed class, and compatibility with your device. For example, if you need a microSD card for recording 4K video, you will need a card that has a UHS Speed Class of U3 or higher and a Video Speed Class of V30 or higher.
