How the Hard Drive has Evolved Over the Last 50 Years

By Jason Sloan


The disc drives of today are compact enough to be small, tough enough for any environment (be it home, office or mobile) and of a capacity to store data which is a little short of incredible. Against this, the earlier hard drives were big in size, too sensitive to be used anywhere apart from a specially protected data center and, by modern standards, sometimes had small memory capacity.

The first hard disk drives were the dimensions of fridges and had giant motors which needed the employment of high current or a three-phase power supply. Today hard disk drives of desktops, now have 500 to 1,000 gigabytes of loading capacity, with some well into the terabytes.

Few products in history have shown such dazzling reductions in cost and size accompanied by an increase in refinement and performance as disk drives.

50 years back

In 1956, the 1st disc drive was introduced by IBM. It had 50 pieces of 24-inch platters which were accessed by a single head assembly, making the access time awfully low at 1 second.

This was improved a touch in 1961 with the development of a hard disk drive whose info surfaces were accessed faster with the utilisation of flying head or multiple heads with self-acting air bearings.

40 years ago

The first disc drive of low mass and low load heads used lubricated media and was introduced in 1973. This technology is now being employed by almost all hard drives.

20 years ago

The 1980's was the genuine beginning of an era of personal computers and internal hard disk drive drives became the trend. External hard drives stayed popular notwithstanding, as some computers didn't have easily access hard disk bays.

The Present

Since its inception, the world has not looked back but has gone on to do nothing less than amazing exploits in the improvement of hard drives. Corporations are now outwitting one another in coming up with hard disk drives of ever bigger loading capacities.

The timeline of the development of disc drives is dotted with such closely-spaced undertakings of progression. In 2002, for example, 137-GB hard disk drives were first sold. Just three years after, a 500-GB drive came out and in less than a year after, the loading capacity jumped right up to 750 GB.

In 2007, the first 1-terabyte drive was released and last year, a 3-TB arrived, this year 4TB has just been released.

The Future

Revolution, not evolution, might be the better term to explain the advance of hard disk drives, and who can say what size hard disks will be in future years.

And to think, on most days we would frequently dismiss along the lines of "a 20gb hard drive? ! I'll never fill that in 1,000,000 years, what a waste of money"

If you are in need of a hard drive recovery talk to the data recovery professionals as quickly as possible for a free consultation. The sooner your drive is examined by a professional, the larger the chance of successfully recovering info from it are.
