Disc 10MB of incredible size: To get hard drives to the point we know today have gone through many stages. Imagine that the 1 terabyte landmark has just reached 2007, that is, it took 51 for years to come. The 2 terabytes came much faster, 2009, that took only 2 years.
This difference gives us an idea of the growth rate of digital storage technology that was actually launched by 1956.
But the evolution of the capacity is not the only impressive element, since there have been very significant changes in the size and the price of hard drives.
Until 1957, data was stored in Movies. Then for the first time IBM presented the hard drive 305 RAMAC (Random Access Method of Accounting and Control). It consisted of 50 boards, had a diameter of 24 inches and a total capacity of 5 MB, a huge capacity for the time.
Ο disc it cost $35,000 a year (rental because IBM didn't sell the drive) and was twice the size of a refrigerator.
The first model, which used "Float on air" technology in the read/write head was called the Winchester 3030 (because the technology was developed in Winchester, England). This particular disc had two sides and each of them could store 30 MB!
Ο below disk which we present today, is presented by Dr John E Kelly III and concerns a hard capacity 10MB. Build 1960.
