The hard drive is one of the most important components of every computer.
Its actual name is hard disk drive or HDD.
It uses two disks that are also known as platters and it stores the data that is previously encoded digitally.
The modern hard drives are sealed but thing were not the same in the past.
In the past the media was removable.
Born In 1956
The hard drive does not have a very long memory as it first appeared in 1956.
The hard drives are different from RAM.
RAM is the volatile memory while hard drives represent the actual memory or the physical one.
This means that the data is not deleted once you turn off your computer whilst RAM does not retain anything.
The data stored is not in the form of actual data because it uses the binary form with only two numbers: 0 and 1.
The platters are the only non-magnetic parts and they are covered in aluminium, however, there are versions with glass coverage too.
Usually, a hard drive has a disk space of a few hundred GB or more, but things were not always this way.
In the past, people who had a 4GB hard drive considered themselves lucky.
However, with the technology developments the hard drives of today are typically between 100GB and 1500GB in size.
The rotation speed is also important when it comes to the hard drive’s capacity and usually hard drives have a 7,200 RPM speed.
There are also higher speeds preferred by gamers with more than 10,000 rotations per minute.
The data compression research is the segment that allows bigger and bigger disk sizes to appear.
However, in many cases, average people do not need them.
A 500 GB hard drive is the same with a 1000 GB hard drive for a person who only uses his computer for listening to music or watching YouTube.
