Knowing Your Hard Drive Technology.

Most ordinary people do not understand the problem hard drive, they only know the size and space or a trademark, but did not see the other subject. Hard drive is a secondary storage device where data is stored as magnetic pulses on a rotating metal disc that is integrated. Data is stored in concentric circles called tracks. Each track is divided into several segments, with sector.To deikenal perform operations to read and write data to and from disk, hard disk using the head to do it, which was in every dish. The head was then moved to find a sector of a particular sector to carry out operations against him.The time needed to find a sector is called seek time. After finding the desired sector, the head will rotate to look for tracks. The time needed to find a track called latency.
