Classification of memory cards by class is intended to determine the capabilities of existing SDHC and microSD cards. The class is indicated on the map itself and looks like a number in a circle.
Instructions
Step 1
All memory cards are divided into four classes and belong to the 2nd, 4th, 6th or 10th class. These numbers are indications of the minimum write speed provided by this card. Values are specified in Megabytes per second. Thus, the number 2 in a circle on the memory card means that this card belongs to the second class and has a minimum write speed of 2 MB / s. This indicator is important for digital devices that perform high-speed recording or do not have a very large clipboard. These devices require a memory card of the appropriate class.
Step 2
Class II cards are the cheapest because they have the slowest write speeds. However, they are great for audio and video players, printers and photo frames. It is not recommended to use second class memory cards in cameras and camcorders, as these devices are designed for active recording.
Step 3
The fourth class of memory cards implies a minimum write speed of 4 Mb / s, which makes this class optimal for use in non-professional cameras. Home photography is a great example of where this class is applied.
Step 4
Recording speeds of 6MB / s make Class 6 memory cards ideal for mid-range digital cameras. These cards will provide reasonably high quality JPEG or RAW footage.
Step 5
The tenth class of memory cards provides recording with a minimum speed of 10 Mb / s and is designed to work with expensive professional photo and video cameras. The rather high price for the tenth class memory cards is explained by the extended functionality of such cards:
- Support for Full HD video recording;
- the ability to shoot in RAW format;
- option for fast burst shooting with high quality;
- up to 32 GB of memory.
It should be especially noted that the burst function makes Class 10 memory cards indispensable for recording various sports events.
