What Should Be the Allocation Unit for SD Card?

Geeks - The allocation unit size is the size of the blocks that the operating system uses to store data on the SD card. The best allocation unit size for an SD card depends on how it will be used.

For example, if the SD card will be used to store large files, such as videos or high-resolution photos, a larger allocation unit size may be more efficient. This is because a larger allocation unit size allows the operating system to store more data in each block, which can improve performance. On the other hand, if the SD card will be used to store many small files, such as text documents or small images, a smaller allocation unit size may be more efficient. This is because a smaller allocation unit size allows the operating system to store more blocks on the SD card, which can improve the ability to access small files quickly.

In general, the best allocation unit size for an SD card will depend on the specific needs of the user. It is typically recommended to use the default allocation unit size that is provided by the operating system, as this will provide a good balance of performance and storage capacity. However, some users may want to experiment with different allocation unit sizes to see which one works best for their specific needs.
