10 Fun Facts About Storage

TECH HISTORY: The New York Times had a nice story about dressy hard drives that reminded me how much of our digital lives are dependent on this often ignored low-margin business. As mentioned before, from iPod to TiVo to our set-top boxes – everything is touched by storage.

Times story reminded me of this quote from Storage maverick Al Shugart, who may have passed onto the beaches of Heaven, but he still lives amongst us, reminding us how much we owe him and his generation.

“Make it bigger, faster, cheaper,” Shugart, founder of Shugart Associates & Seagate Technology, once famously said. Seagate Technology — originally Shugart Technology Inc. — sold a a 5.25-inch, 5-Mbyte drive for $1,500. The industry is still working hard to make sure that Shugart’s words still ring true. Sure things have changed a lot since then. Have a look… and see how much.

  • The magnetic HDD is 50 years old (#). In 1956 IBM introduced 305 RAMAC (random access method of accounting and control), which is like the great-great-great grandfather of today’s disks. It was the size of a refrigerator, and stored a total of 4.4 megabytes on 50 doubled-sided, two-foot-diameter disks. The disk had a density of 2,000 bits of data per square inch and had a purchase price of $10,000,000 per Gbyte. (#)
  • Today’s laptop drives are typically 2.5 inches and are a size of a deck of cards, and can store upto 160 gigabytes – or 131 billion bits per square inch. Price is less than $1 per gigabyte. (#)
  • Consumers bought 739.7 million gigabytes of hard-drive storage space last year. That is 11 times what they bought in 2003. (NYT)
  • In the U.S. alone, $600 million worth of external hard drives were sold in 2006, up 53% from 2005, The NPD Group, a market research firm, says. (NYT)
  • External hard drive prices declined 28.4% from $197 in 2003 to $141 in 2006 and the amount of storage space on the drives doubled.(NYT)
  • Per Gigabyte retail price of hard disk drive storage in 2003 was $2.04, but in 2006 it was 77 cents, according to The NPD Group.
  • The recording density for data — aka capacity — has increased 60,000,000-fold in 50 years. (#)
  • The amount of worldwide information is projected to grow from 161 exabytes in 2006 to 988 exabytes in 2010. An Exabyte is a million terabytes.(WWD)
  • By 2010, the total amount of data will overwhelm the total amount of digital storage by a factor of nearly 2 to 1. 2007 is the year that our ability to stuff bits into the digital universe will outstrip our ability to store them.(WWD)
  • Research shows that in large-scale IT installations, the annual disk replacement rates typically exceed 1%, with 2-4% common and up to 13% observed on some systems. (#)
