Suppose

we have a disk drive with the following parameters:

Average seek time $=12$ milli seconds

Rotation speed $=7200$ revolutions per minute

Data transfer rate $=$

$3\mathrm{.}5$ MBytes $|$ second

Sector size $=1024$ bytes

$($a$)$ What is the average

time to read a

single sector?

$($b$)$ What is the average time to read data from $8$ consecutive

sectors

on the same

cylinder
