The storage capacity of a memory card refers to the amount of data the card can hold. Common sizes range from a few gigabytes (GB) to several terabytes (TB). The capacity you need depends on your specific application. For basic photography or low-resolution videos, a smaller capacity may be sufficient, while for 4K videos or large photo files, it's better to choose a card with a higher capacity.
Each device usually supports only one type of card. On the market there are several mutually incompatible formats which differ not only in size but also by identifying for a specific product.
Read speed indicates how fast the device can read data from the memory card. Higher speeds are desirable for intensive tasks such as transferring large files or watching high quality videos directly from the card.
The write speed determines how fast the device can write data to the memory card. It is a key parameter for activities where fast writing is required, such as high definition video recording.
UHS (Ultra High Speed) Class is a standard that refers to higher speed classes of memory cards. UHS-I, UHS-II and UHS-III are different variants that provide different minimum write speeds, ranging from 104 MB/s to 624 MB/s. These cards are ideal for professional video and photography applications where fast and reliable performance is required. UHS classes are also accompanied by U1 and U3 classes, which indicate specific minimum speeds of 10 MB/s and 30 MB/s respectively.
