Hi, I going to interface a microcontroller with SD flash memory card for data log. How to caculate the needed memory capacity?
Thanks

To calculate the needed capacity of an SD flash memory card, you will need to consider the size of the files you plan to store on the card. This can include documents, photos, videos, and other types of data. Once you have a rough estimate of the total size of your files, you can then determine the capacity of the SD card needed to store them all.
Aside from the size of your files, you should also consider the future growth of your data. If you anticipate adding more files in the future, it may be wise to choose a higher capacity SD card to accommodate this growth. Additionally, consider the type of files you will be storing as some, such as high-resolution videos, may require more space.
You can easily convert file sizes to determine the needed capacity of an SD card. For example, if you have a 2GB file and plan to store 100 of them, you will need a minimum of 200GB of storage space on your SD card (2GB x 100 = 200GB).
Yes, there is a maximum capacity for SD flash memory cards. Currently, the maximum capacity for a standard SD card is 2TB (terabytes), while the maximum capacity for a microSD card is 1TB. However, keep in mind that these maximum capacities may change in the future as technology advances.
In addition to file size and future growth, you may also want to consider the speed of the SD card. Higher capacity cards may have slower read and write speeds, which can affect the performance of your device. It's important to balance your storage needs with the speed of the card to ensure optimal performance.
