The overall data transmission rate with disk drive latency 7 ms, and a burst bandwidth of 2 MB per second

Query:

A 4 K byte block of data is read from a disk drive. What is the overall data transmission rate if the disk drive has a latency of 7 ms, and a burst bandwidth of 2 MB per second?

Solution:

Total time=4K/2mb+7ms=9 ms
Over all transmission rate=4KB/9ms=0.44Mb/s
