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.

What exactly is a magnetic disk?
How do Magnetic Disk Drives (HDDs) differ in operation from Solid State Drives (SSDs)?
Calculate the access time for a disk having the size of 512 byte/sector and the seek time of 12ms. The rotational rate is 5700 RPM. The data transfer rate is 3MB/sec, and the the controller overhead is 1ms, you may even assume that there is no service time for the access.
