Computer Architecture-Secondary Memory

Question

Susheel is setting up a website. He bought a fancy new hard disk which advertises:
• an 8 ms average seek time.
• 10000 RPM or roughly 6 ms per rotation.
• a2 ms overhead for each disk operation.
• a transfer speed of 10,000,000 bytes per second
Susheel had enough money left for a 10,000,000 bytes per second network connection. His system bus has a maximum baqndwidth of 133 mega bytes per second and his HTML files have an average size of 8000 bytes. How much time will it take on an average to read a random HTML file from the disk?

@Tesla

transfer time will be .8 microsec

not milisec

14.06 ms

8 ms(seek time) + 3 ms(rotational time) + 0.8 ms(transfer time) + 2ms(overhead) =13.8 ms

Answer 1

Answer is 13.8 ms

as 8ms ( seek time ) + 2 ms ( disk overhead) +  0.8 ( for transfer bottle neck bandwidth will be used which is 10Mbps not 133 Mbps )
