The speed performance of cards vary based on the type of SD bus in the camera — whether it is high speed or ultra-high speed UHS. Above is an example of the Nikon D listing its SD bus type.

You can find this information in most camera manuals. They try to provide manuals for each camera when available. Most can be found online somewhere. The SD Card Association chart below provides a helpful graphic to visually demonstrate what speed-classes of SD cards are appropriate for different types of video projects:.

I either need to choose a longer interval or use a faster card. They all refer to the same thing. Multiply, for example, a Lexar card with an x-rating of x by.

Like all storage media, such as hard drives, SD cards have a file format, which dictates the maximum amount of data that can be stored on the card. This refers to the type of UHS bus needed by the host hardware i. This value gives the amount of data in total that the card can safely carry. Now that we have explored the various properties of the most common video memory cards, how do you chose which one to use for your next project?

Consumers can find the best card for a host via Speed Class symbol match; choose the same or higher class symbol card than class symbol of the host indicated. Video Speed Class is also the same.

Note that expected write speed will not be available by a combination of different class symbols between host and card such as Host Class 10 and Card U1, Host U1 and Card V10, etc. By repeating deletion and write of files, data area is gradually fragmented and it influences write speed. Generally, write speed to a fragmented area is slower than sequential write speed due to flash memory characteristics.
