Memory cards come in many varieties.
Not all memory cards are created equal, and they do not all perform the same functions. Deciphering different memory cards is important. Every memory card has symbols and data on the label to inform customers of the card's abilities to record digital data. Memory cards can be used for both photos and videos, but the quality differs depending on the card's class and write speed. When you purchase a memory card, skipping over these details could mean missing out on important information or possibly losing important memories.
Instructions
1. This memory card is 16GB.
Decide what card size you need. The number of gigabytes determines how much data (or how many photos) your memory card can store. A 2GB card typically holds 500 to 600 photos, depending on the photos' file sizes. Photos with higher resolution and clarity take up more space. Standard cards for simple point-and-shoot cameras range store from 2GB to 32GB. A 2GB card may be sufficient, but for vacations and other times when you cannot clear your memory card often, choose a larger-capacity card.
2. Read the card's class, which is signified by a number enclosed within a semicircle. This number is usually a 2 or a 4, but it can go up to 10. The class of a card relates to the quality of video a card can record. The greater the number on the card, the better the quality video it can record. Cameras that can record HD video require a card in class 4 or higher.
3. Consider the speed, which appears on most labels as a number measured in megabytes per second. The higher the speed on the card, the faster you can transfer data. The read speed is found only on higher-end secure digital high-capacity cards (SDHC).
