A Brief Explanation Of Hard Drives

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 inĀ 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.

Buying A Hard Drive

This is why you have to assess your needs and purchase your hard drive accordingly.

There have been a lot of changes in the hard drive world and a lot of them are happening these days too.

In order to make sure that you make the right decision when purchasing a hard drive, you should research this domain a little bit.

Researching will help you make the right decision and you will get the best for your money.

However, the general rule is that more expensive hard drives are also of higher quality.

In conclusion, the hard drive is indispensable to any computer and it is one of the most important components of every computer too.

When you decide upon getting a computer or choosing a new hard drive you should definitely check the hard drive’s storage capacity and speed.
