SD Card 2 GB Семейство SD card (Secure Digital Card)
Class rating for video on SD cards: conventional data and photos are written to the memory card in individual sequences with interruptions. This process allows the card's full write speed to be utilised. Videos on the other hand must be written with a sustained speed. This does not match the card's maximum speed. Speed classes have been introduced to make it easier to select the right card for camcorders:
Class x: x stands for the number of MB/s of sustained write speed
Class 4 = 4 MB/s of sustained write speed
Class 10 = 10 MB/s of sustained write speed
UHS = New Bus system for UHS compatible cards, UHS-I over 10 MB/s of sustained write speed
High-definition (HD) camcorders require Class 4 or above
The Class Rating is only required for filming videos Технические параметры
