Hard drive and storage solution manufacturer Seagate has announced that it has delivered its 1.5 billionth drive as of 20 October 2010, with this milestone coming only two and a half years after shipping its one billionth drive.

 

The company celebrated its billionth hard drive sold on 22 April 2008, for which the number of drives sold at that stage amounted to 79 million terabytes of storage space. This is roughly enough storage space to store 158 billion hours of digital video or 1.2 trillion hours of your favourite music.

 

Seagate’s latest milestone of 1.5 billion hard drives equates to around 118.5 million terabytes, which amounts to enough storage place for about 237 billion hours of digital video or 1.8 trillion hours of music.

 

Even more impressive than the figures is the time-frame in which it has been achieved. The first milestone of a billion drives took the company 29 years (1979 to 2008) to reach, whilst the latest milestone of an additional 500 million drives took only two and a half years (2008 to 2010). Seagate calculates that at this rate, the two billion mark for drives sold will happen within the next two years - easy to believe since the demand for storage space is only increasing as the demand for HD video grows.
