Suppose you have a hard drive that spins at 9000 RPM , and has 100 sectors of 512 bytes each on a particular track. If the head is already in position when a request for two adjacent sectors of that track is serviced , what is the expected effective data rate to get the data into the controller's buffer? Give the answer in Bps , with 3 significant digits.

Answer:

Check the explanation

Explanation:

The expected effective data rate (which refers to the average amount of units of data, such as characters, bits, frames, blocks, or the transfer rate per unit of time from a source and received as valid by a sink. ) to get the data into the controller's buffer is calculated below.

Number of rotations per minute=9000

Number of sectors=100

Number of bytes for each sector=512

Given head is already in position .

effective data rate=9000*100*512/60

                        =8192000 bytes per sec
