The hard disk is one of the computer’s memories and an indispensable part of the computer. Due to the development of science and technology, from the birth of the first hard disk in 1956 to now, the hard disk has undergone great changes. Today, DiskMFR will take you to a simple understanding of the development history of the hard disk to see how the hard disk has changed from a behemoth to a smaller and smaller hard disk.
Gaint Hard Drive
In 1956, IBM invented the world’s first HDD:350RAMAC. The hard drive had 50 24-inch disks and was only 5MB, but it was as big as two refrigerators and weighed more than a ton, and was used in industry at the time. Although 350RAMAC can not be called a hard disk in a strict sense, it has opened a new page in the history of computer development.
In 1973, IBM launched the Winchester hard drive, which is the ancestor of the hard drive we use today. the basic architecture of the hard disk has been established.
In 1980, the first GB capacity hard drive + the first home hard drive was born. IBM launched IBM 3380 in 1980, with a capacity of 2.5GB.
Unlike today’s lightweight hard drives, the IBM 3380 weighs more than 500lbs.
Small HDD becomes mainstream
The world’s first 5.25inch HDD: ST-506 was born, with an initial hard disk capacity of 5MB, which is the first hard disk product for individual users. In 1997, the GMR giant magnetoresistive effect magnetic head was born, and the storage density can reach 10: 40Gbhand inch2, which is as much as 8 times higher than before, which makes the storage density of the hard disk to a higher level. In 2007, the hard disk exceeded the TB capacity.
In some applications, SSD has replaced it.
Since 2012, the development of HDD technology has almost stagnated. Especially on the PC side, SSD has replaced the existence of HDD. With the advantages of fast reading and writing speed, good shock resistance, low power consumption, zero noise, and strong environmental applicability, SSD has gradually become the mainstream choice in the market.
As far as the current price is concerned, 128g SSD is close to 500g HDD. Although SSD does not have an advantage in price, it has successfully replaced the application of HDD on PC because of the above advantages. Of course, generally, SSD and HDD will be used together. The SSD of Hongwang ICMAX has the characteristics of lightweight, small volume, mute, fast reading and writing speed, low power consumption, strong impact resistance, etc., and is widely used in military, vehicle, industrial control, video surveillance, network surveillance, network terminals, power, medical, aviation, navigation equipment, and other fields.
In summary, it is not difficult to see that from the history of the development of hard disk, due to the development of science and technology and people’s demand for portable electronic digital devices, the volume of the hard disk becomes smaller and the capacity becomes larger. However, due to the different application fields of HDD and SSD, it is still unlikely that SSD will completely replace HDD in the future, but in the long run, due to the cost reduction of technological innovation, such as QLC flash memory technology and 3D TLC technology, whether SSD will eventually replace HDD, in the foreseeable future remains to be tested.
