What does Class 10 mean?

Class 10 is one of the original speed classifications used to indicate the minimum sustained write performance of a microSD™ card. A Class 10 rating means the card is capable of maintaining a minimum sequential write speed of 10MB per second, making it suitable for Full HD video recording and a wide range of everyday storage applications. Today, Class 10 remains one of the most widely recognised performance standards across compatible devices.

Every TrailBit™ system is validated to the Class 10 standard as part of its overall performance specification. While newer ratings such as U3 and V30 provide additional performance information for higher-resolution recording, Class 10 continues to demonstrate that TrailBit™ meets an established industry benchmark for dependable recording performance. Together, these standards help ensure your microSD™ card is ready for compatible recording devices.
