1.	Explain the structure of Hard Disk with factors which affect data accessing time of hard disk.
Answer» Theaccess timeorresponse timeof a rotating drive is a measure of the time it takes before the drive can actuallytransfer data. The factors that control this time on a rotating drive are mostly related to the mechanical nature of the rotating disks and movingheads. It is composed of a few independently measurable elements that are added together to get a single value when evaluating the performance of a storage device. The access time can vary significantly, so it is typically provided by manufacturers or measured in benchmarks as an average.For SSDs this time is not dependent on moving parts, but rather electrical connections to solid state memory, so the access time is very quick and consistent.Most testing and benchmark applications do not draw a distinction between rotating drives and SSDs so they both go through the same measurement process
