Using a larger block size in a fixed block size file system leads to :...
Using larger block size makes disk utilization poorer as more space would be wasted for small data in a block. It may make throughput better as the number of blocks would decrease. A larger block size guarantees that more data from a single file can be written or read at a time into a single block without having to move the disk ́s head to another spot on the disk. The less time you spend moving your heads across the disk, the more continuous reads/writes per second. The smaller the block size, the more frequent it is required to move before a read/write can occur. Larger block size means less number of blocks to fetch and hence better throughput. But larger block size also means space is wasted when only small size is required and hence poor utilization.

Using a larger block size in a fixed block size file system leads to :...
Introduction:
In a fixed block size file system, the data on a disk is divided into fixed-size blocks or sectors. The block size determines the minimum amount of data that can be read from or written to the disk at one time. Choosing a larger block size can have implications on disk throughput and disk space utilization.
Explanation:
1. Disk Throughput:
Disk throughput refers to the rate at which data can be read from or written to the disk. When a larger block size is used in a fixed block size file system, it leads to better disk throughput. This is because larger blocks allow more data to be transferred in a single I/O operation, reducing the overhead of seeking and accessing different blocks. This results in improved efficiency and faster data transfers.
2. Disk Space Utilization:
Disk space utilization refers to the efficient utilization of disk space to store data. When a larger block size is used, it can lead to poorer disk space utilization. This is because if the file size is smaller than the block size, the remaining space in the block is wasted and cannot be used to store other data. This phenomenon is known as internal fragmentation, where unused space within a block reduces the overall storage capacity of the disk.
Conclusion:
In conclusion, using a larger block size in a fixed block size file system leads to better disk throughput but poorer disk space utilization. While larger block sizes improve the efficiency of data transfers and enhance disk throughput, they can result in wasted space within blocks, reducing the overall storage capacity of the disk. Therefore, the choice of block size in a file system involves a trade-off between disk throughput and disk space utilization.
