Q. How would utilize of a RAM disk affect your selection of a disk-scheduling algorithm? What factors would you require to consider? Do the similar considerations apply to hard-disk scheduling given that the file system stores recently utilized blocks in a buffer cache in main memory?
Answer: Disk scheduling attempts to decrease the overhead time of disk head positioning. Ever since a RAM disk has uniform access times scheduling is largely unnecessary. The comparison among RAM disk and the main memory disk-cache has no implications for hard-disk scheduling for the reason that we schedule only the buffer cache misses not the requests that find their data in main memory.
