Let us assume a disk with rotational speed of 15,000 rpm, 512 bytes per sector, 400 sectors per track and 1000 tracks on the disk, average seek time is 4ms. We want to transmit   a file of size 1 MByte, which is stored contiguously on the disk. a. What is the transfer time for this file? b. What is the average access time for this file? c. What is the rotational delay in this case? d. What is the total time to read 1 sector? e. What is the total time to read 1 track for sequential organization?

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.
