The maximum speed for writing data to a memory card.

High write speed is important for tasks that involve storing large amounts of data in a limited amount of time. However, note that this paragraph indicates the theoretical maximum speed for perfect conditions; in fact, this value can be noticeably lower. Therefore, the characteristics of memory cards also indicate the minimum guaranteed write speeds in different modes — the general speed class, the UHS class, the video recording class and/or the class for applications. All of them are described in more detail above. However, you can also evaluate the capabilities of the carrier by the overall speed: other things being equal, a card with a higher theoretical speed will work faster in fact.

As for specific values, speeds from 4 MB / s and from 6 MB / s are practically not found nowadays, from 10 MB / s and from 16 MB / s can be called average indicators, from 50 MB / s — above average, and the fastest models have a maximum write speed of 100 Mbps or more.
