Hard drive – the ferromagnetic rotating disc hard drive, short HDD (hard disk drive) is the slowest part of a computer. Writes the data to a ferromagnetic rotating disk, in the binary numeral system. To do so, the surface is magnetised accordingly. The aforementioned data can be read again by Palpating the magnetization of the plate surface. The size of a disk are fundamentally specified in inches.

Is the two newest and the most used form the 3.5? hard drive and the 2.5?-hard disk drive. In the course of time, these smaller forms of hard drives evolved first, because initially they were a lot bigger and more energy needed a lot. The first drive was built by IBM in 1956, and had a size of 24. In the 1970s was the size 8? shrunk and she was then a few time to 5.25? fallen. Since 1997, s is extinct genus but completely. Were around 1990 the 3.5 “hard drives which introduced today into the desktop computer are installed. In areas where efficiency plays a great role, such as in Server centres, is on the small 2.5 “hard disk set, as this has significantly more storage volume available at same place, and in addition have less power consumption.

2.5? sizes are mainly in notebooks, because they have ideal conditions for your mobile computer. 1.8? hard drives manufactured since 2003, however, Hitachi announced in late 2007, to produce any drives of this size more as these were replaced by the Flash storage. The storage volume is shot extremely in the height over the years.
