This is a 5 Meg Hard Disk in 1956.
In September 1956 IBM launched the 305 RAMAC, the first computer with a hard disk drive (HDD). The HDD weighed over a ton and stored 5MB of data. |

The first computer I ever programmed for had two RAMAC's.

| Did they call them 'hard' disks at that time, since I presume the 'floppy' disk hadn't yet been invented? Or was it just a 'disk'? or perhaps just a 'memory thing-y'? |

| We had a lot of the IBM 2312/2314 compatible disk drives on the comm processor systems that were installed in 1973. They were big, had removeable 20 platter discs and held a whopping 2 megs (not 2 mb) of data. The comm processors had a 64MB core memory in them. |

After puttin' boxes of punch cards thru the IBM 029 keypunch at school from 1971 to 1975, I was impressed in 1976 when the MIS manager came back from a show with an ad from Shugart, showing a 10 inch floppy disk drive that would hold the equivalent of a box and a half of cards (128 kb disk approx equal to 1500 pcs of 80 column records...)
Joey, was that back when computers were steam powered?  |
