Have you ever wonder what was the earliest hard disk ever created? Well, we managed to find one from IBM. In September 1956 IBM launched this gigantic 305 RAMAC. RAMAC is the first computer with a hard disk drive (HDD). This hard disk weights over one tones but its memory storage is quite unbelievably small – 5Mb. 51 years later we are using pen drives as small as a lighter with memory storage of 4GB. How will memory storage be 50 years from now?
