History of hard disk

The hard drive is an important part of computing today, allowing information to be stored and retrieved at a future date. However, the unit now has its roots in the technology that was developed 50 years ago. The first unit was developed in 1956 and looked like they would look like an air conditioner today. Yesterday units had a very small storage capacity, but it took 100 times more space. Since the technology, the capacity of hard drives has developed so long as it took up less space and less.

The first days

The first idea, a memory unit and receiving of data is developed in 1953 by IBM engineers. They recognized the need for a device that a high capacity, can have fast access to data, and is cheap to build. The technologies are considered the first signs of wire, rod arrays and matrices, including the drum. However, the reader was finally resolved when the device of choice because its simple mechanical design and easy. The first drive was the IBM 305 RAMAC, which can store 4.4 megabytes at a price of $ 160 000 in today's money.

1950-1970

The IBM 350 Disk File was a huge success for IBM and the age of the hard drive is officially born. However, the first performance of this device ridiculous compared to what the less expensive devices can achieve today. The IBM 350 Disk File succeeded in information access in less than 1 second - compared to almost all hard drives, which can now access information in a few milliseconds. However, access times and went quickly in 1961, much of the 4000 series drives are able to time of only 50 ms access time. In 1973, IBM introduced the IBM 3340 hard disk. This was the first hard disk, the media smeared the low to ensure a smooth operation and less maintenance was used.

The era of personal computers

When the PC revolution began in the 1980s, was the primary means of storing and retrieving data into a computer via floppy disks. Therefore, the majority of PCs do not have a hard disk because they were too expensive to manufacture and not with the disk in terms of competition, mere storage. However, the 1980s began to the discs as the main method of storage to replace PCs. Occur in the mid-1990s almost all PCs with some kind of internal unity, and are now much cheaper than hard drives in terms of the amount of memory space.

Present

After the disk has become a fixture in the industry of personal computing in the 1990s, further, faster, smaller and larger capacities. Hard drives are currently very cheap and can produce large amounts of information, save the part of the order of 5 terabytes of data. The future of mobile is not clear, but most experts agree that it is removed and with the condition, the most technologically advanced sound equipment is to be replaced. A Solid State Drive has no moving parts and thus get a longer life and easier compared to a conventional hard disk.
