Hard history

Hard drive is an important component of modern day computing, as it allows storage and later access to information. However, thanks to the modern day drive, thanks to technology developed 50 years ago. The first drive was developed in 1956 and resembled the modern air conditioning unit. Yesterday's units had very small storage capacity, but 100 times more space was occupied. During the development of technology, the capacity of hard drives grew, while less and less space was available.

Early Days

The first idea for storing and receiving data was conceived in 1953 by IBM engineers. It has been recognized that there is a need for a piece of hardware that has high capacity and quick access to data and can be cost-effective. Considering the first technology, there were wire matrices, rod blocks, and even drum blocks. However, the disc drive was ultimately chosen for lightweight construction and simple mechanics. The first drive is the IBM 305 RAMAC system, which stores 4.4 megabytes at a cost of $ 160,000 for today's money.

1950s and 1970s

The IBM 350 record file revealed that it had a great deal of success for IBM and the era of hard drive was officially born. However, this first device performance was ridiculous as the cheapest units can now access. The IBM 350 disk file was able to access information in less than 1 second – in comparison, all existing hard disks can now access information in just a few milliseconds. However, the access time soon dropped significantly and in 1961 the 4000 Series disk drives had only 50 ms access time. In 1973, IBM introduced IBM 3340. It was the first hard drive that used the lubricant and the low mass media for smooth operation and less maintenance.

Personal Computer Age

When the Personal Computer Revolution began in the 1980s, the primary tool for storing and retrieving data stored on a computer was via floppy disks. Thus, most PCs do not have a hard drive because they are still too expensive to manufacture and can not compete with floppy disks with clean storage capacity. However, by the end of the 1980s, they began to replace floppy disks as the primary storage method for personal computers. By the mid 1990s virtually every personal computer was delivered with some internal drive because they were much cheaper than floppy disks, according to the size of the available storage.


After the hard drive came into the personal computer industry in the early 1990s, it grew faster, to a lesser extent and increased capacity. Hard drives are now extremely inexpensive and can store large amounts of information, some of them up to 5 terabytes of data. The future of handsets is unclear, but most experts agree to be gradually dismantled and replaced with a more technologically advanced solid-state drive. The solid state drive does not have any moving parts, so it has a longer lifespan and easier maintenance than normal hard drives.
