Answer:
One scenario where choosing a large file system block size might be a benefit is when the file system is used to store large files, such as video or audio files. In this case, a larger block size can reduce the number of blocks needed to store the file, which can improve performance by reducing the amount of disk seek time required to access the file.
An example of where a large file system block size might be a hindrance is when the file system is used to store many small files, such as text files or images. In this case, a larger block size can result in wasted space because each block may contain only a small amount of data from a single file. This can reduce the overall capacity of the file system and may cause performance issues if the file system becomes fragmented.
