The IBM 305 RAMAC, which debuted in 1956, was the aboriginal computer with a harder drive. It was 16 aboveboard feet, advised over a ton, and had to be transported by plane. But it abiding as Hell exhausted bite cards.
We generally accuse about bequest appearance captivation aback new technologies. For the computers of the aboriginal 1950s, bite cards were a hundred-year old bequest feature. Though they were calmly destroyed and abundantly inefficient, they remained the absolute average for abstracts accumulator throuhgout the aboriginal bisected of the 20th century. Until IBM formed out the 305 RAMAC.
It was the aboriginal bartering computer to use a affective arch harder deejay drive, autumn 5 actor characters of accounting data, the agnate of 64,000 bite cards, on 50 24" alluring disks. To put it in today's terms, the colossal apparatus captivated about 5MB of data. Its alluring disks were accessed by two arms, controlled by vacuum-tubes, that were audibly adequate by aeroembolism air.
But still, for companies, the advantages were obvious. The 305 RAMAC—the name stands for Random Admission Method of Accounting and Control—could accord with a array of ascribe sources, including bite cards, and could abundance and admission aberrant amounts of abstracts with absurd speed. Perhaps added importantly, it was the aboriginal computer to action random admission to data, area antecedent accumulator tapes had to be run from alpha to accomplishment to acquisition the appropriate section of information. Compare the accomplishment it takes to define a moment on a cassette band to award that aforementioned moment on a CD. Now anticipate of that advance in agreement of the abstracts accessed by every ample association or authoritative bureau in the country. Yeah, the 305 RAMAC was a big deal.
Here's how IBM pitched the computer in 1956:
By the time assembly ended, in 1961, IBM had bogus over 1000 305 RAMACs, which had been busy to companies for $3,200 a month. But for those companies, it was account it—the bulk of abstracts they could abundance and the acceleration with which they could admission it was acceptable more important to their basal lines. And it was their investments in the 1950s that pushed the development of harder drives like those begin in the 305 RAMAC, shrinking them to the ones we use in our accessories today.
