How to determine a memory card class
Classification of memory cards by class is designed to determine the capabilities of existing SDHC and microSD cards. The class is indicated on the map itself and looks like a figure in a circle.
Instructions
1
All memory cards are divided into four classes andrefer to 2, 4, 6, or 10th grade. These figures are indicative of the minimum recording speed provided by this card. Values are determined in megabytes per second. Thus, the number 2 in the circle on the memory card means that this card belongs to the second class and has a minimum write speed of 2 MB / sec. This indicator is important for digital devices that perform high-speed recording or have a very small buffer of exchange. For such devices, memory cards of the appropriate class are required.

Second-class memory cards are the cheapest,because they have the slowest write speed. However, they are great for audio and video players, printers and photo frames. It is not recommended to use memory cards of the second class in photo and video cameras, since these devices are designed for active recording.
3
The fourth class of memory card impliesa minimum write speed of 4 MB / s, which makes this class optimal for use in non-professional cameras. Home shooting is a perfect example of where this class is applied.
4
The recording speed of 6 MB / s makes the memory cards of the sixth class ideal for use in digital cameras of the middle level. These cards will provide a sufficiently high quality of shooting in the format of JPEG or RAW.
5
The tenth class of memory cards provides recording froma minimum of 10 Mb / s and is designed to work with expensive professional photo and video cameras. A fairly high price for memory cards of the tenth grade is explained by the expanded functionality of such cards: - Full HD video recording support; - RAW shooting capability; - Fast burst shooting with high quality; - Memory capacity up to 32 GB. , that the serial shooting function makes the memory cards of the tenth grade irreplaceable when recording various sports events.
