I need to know how much data is stored worldwide, and what the trend
are for the next 5 to 10 years. Specifically, I am interested in what
those 5 to 10 year estimates are for personal storage usage. How much
digital data store are we all expected to have in the next 5 to 10

Hello again Joel,

A team of researchers from the School of Information Management and
Systems University of California, Berkeley released a study How Much
Information? that chronicles the information explosion over the past several years.


?This study is an attempt to estimate how much new information is
created each year.?

?Information is recorded, stored and distributed in four physical
media ? paper, film, magnetic, and optical. Good data is available for
the worldwide production of each storage medium, providing an upper
bound for the potential production of original information and copies.
There are often good estimates for how much original content is
produced in each of these different storage formats, particularly for
the advanced economies that produce the most information.?

The summary of findings can be found at this link:

Growth: from 322 GB per home in 2005 to 1,933 GB in 2010

?According to TDG"s latest report, The DNA of the Digital Home: Trends
in Digital Home Storage, the amount of personal content or home
reference data generated by the use of consumer electronic devices
will grow from about 322 GB per home in 2005 to 1,933 GB in 2010.?

Other key findings of TDG"s new study include: 

?Storage devices networked in the home today are predominately
external single disk drive storage boxes attached directly to home
computers such as external USB interface drives.

Only 21% of broadband households are familiar with network-attached
storage (NAS), and only 3% currently use a network-attached storage

Storage capacity, speed of file transfer/backup, and price are the
most important considerations in determining which storage solution
consumers are likely to purchase.

Total NAS home units will exceed 15 million units by 2010, with about
25% being multiple drive (RAID) storage systems.?

Coughlin Associates' recently released 2005 Integration of Digital
Storage into Consumer Electronics Report shows strong growth in
digital storage for consumer electronics applications.

Summary of trends:

?By 2010 we expect that close to 40% of total shipped hard disk drives
will be used in consumer applications, up from about 14% in 2004.?

?By 2010 3.5-inch disk drive will comprise about 31% of the total
volume, down from 67% in 2004.?
?One inch disk drives with capacities of 8-10 GB using perpendicular
recording will be available by the second half of 2005.?
?One inch drive capacities of up to 20 GB could be available by the end of 2006 
By 2006-2007 we will see 1 TB 3.5-inch hard disk drives.?
?Home reference data could growth from 322 GB in 2005 to 1,933 GB by
2010 for a digital home.?

?Total networked attached storage in the home could total about 15
million units by 2010, with about 25% of this number being multiple
drive (RAID) storage systems.?

Figures for High Density Hard Disk Drive Trends in the USA


Accoroding to Research firm IDC's "Worldwide Hard Disk Drive 2005-2009 Forecast," 

Hard disk drives could reach 1 terabyte in capacity sometime in 2007 to 2008.

"We could get to 2 terabytes by 2009, but it is more likely that it
will be a stronger adoption of 1-terabyte machines for things like a
TiVo or digital video players," Reinsel said. "Customers want their
media whenever they want it. It's not that they have a fear of losing
it that is holding people back from adopting 2 terabytes, but fear of
not having enough space to record their favorite episode."

?In-Stat/MDR predicts that the number of consumer devices containing
hard disc drives will balloon over the next few years, from
approximately 5 percent of the world?s hard disc drive market in 2003
to close to 33 percent by 2008.?
