TF card performance standards
In addition to capacity, the performance of TF cards (i.e. data reading and writing speed) is also very important, especially when used for high-definition video recording, game storage, or large file transfers. The performance of TF cards is usually identified by speed class:

• Class 2, 4, 6, 10: Indicates the lowest continuous write speed, Class 10 is currently the most common standard, representing a minimum write speed of 10MB/s.
• UHS-I, UHS-II, UHS-III: These are high-speed interface standards, with UHS-I typically reaching speeds of up to 104MB/s, and UHS-II and UHS-III higher.
• A1, A2: These marks indicate that TF cards support application performance, such as quickly launching and running applications, especially for Android smartphones and other high-performance devices.

• TF card is the old name of microSD card, usually used in smartphones, digital cameras, tablets and other devices.
