Problem 3
Suppose I have a disk such as the 320GB SATA drive described here
and I
have a workload consisting of 10000 reads to sectors randomly
scattered across the disk. How long will these 10000 request take (total)
assuming the disk services requests in FIFO order?
Problem 4
Suppose I have a disk such as the 320GB SATA drive described here and I have a workload consisting of
10000 reads to 10000 sequential sectors on the outer-most tracks of
the disk. How long will these 10000 request take (total) assuming
the disk services requests in FIFO order?
Problem 5
Suppose I have a disk such as the 320GB SATA drive described here and I have a workload consisting of
10000 reads to sectors randomly scattered across the disk. How long
will these 10000 request take (total) assuming the disk services
requests using the SCAN/Elevator algorithm.
Problem 6
Suppose I have a disk such as the 320GB SATA drive described here and I have a workload consisting of
10000 reads to sectors randomly scattered across a 100MB file, where
the 100MB file is laid out sequentially on the disk. How long will
these 10000 request take (total) assuming the disk services requests
using the SCAN/Elevator algorithm?
