As digital electronics continue to replace legacy analog consumer electronics
in the home, the need for digital content storage (either embedded or
network-capable) will grow concurrently. The adoption of digital
cameras and DVD recorders, as well as the widespread use of the home
PC as a media device, have led to a notable accumulation of digital media
content in the home. As this digital evolution continues to play
out, the amount of storage required to support the average consumer home
will grow. Those companies that have an intimate understanding
of how consumers use new digital electronics will have the early lead
in designing storage solutions that are best positioned for widespread
diffusion.
Chipset Trends: An Early Indicator of Growing Storage
Needs
Storage needs can be tracked against trends in chipset development
and deployment: the more powerful and capable chipsets become,
the larger the data files that can be manipulated, and (hopefully)
the more robust the user experience (faster speeds, more refined images,
better control).
Storing these files, then, soon becomes an issue. As the chipset
evangelists often say, the more powerful the chipset, the more data will
be created – a phenomenon that has direct implications of storage
requirements.
A number of new chipsets including IBM/Sony/Toshiba’s Cell, Intel’s
Viiv platform, and TI’s new DaVinci processor will soon be available
for use in the next generation of stationary and mobile media devices. Once
these types of advanced platforms find widespread usage – it is
not a question of if, but when –no doubt storage requirements
will advance as well.
Storage Options: Today and Tomorrow
Digital storage in the home has been primarily the province of personal
computers until the last few years. Starting in the mid-1990s
a new category of storage devices began to appear in the home, digital
storage for consumer electronics. Since the first appearance
of semiconductor flash memory music players and digital cameras, as
well as the appearance of digital video recorders (DVRs) using hard
disk drives to store television programming, digital storage has become
an important aspect of entertainment both inside and outside the home. The
vast majority of digital consumer electronic devices – whether
DVRs, home media centers, digital cameras (both still and video), and
portable media players – now commonly use some type of digital
storage component such as hard disk drives, optical disks, and flash
memory. Digital storage-based devices are also becoming more
common in automobile navigation and entertainment systems as well as
in cell phones.
In the next five years, all digital homes will ultimately include some
form of digital storage, whether housed in specific devices such as those
listed above or connected to a network that serves a variety of connected
devices. In addition, consumer data (that is, personal still and
video images, movies and music, as well as personal computer files) are
likely to be stored off-site, perhaps through an SSP (Storage Service
Provider), a new type of service provider used to preserve a household’s
digital content in the event of a “disaster” that results
in the destruction of data collected among the various devices in the
home.
The table below lists several examples of home storage with usage notes
and optimal storage types.

The well-furnished digital home in 2005 has a single drive DVR/PVR/STB,
a desktop computer, a laptop computer, a digital portable music player,
and an external storage device. By 2010, this same home will include
a multi-room PVR with attached storage devices, a home NAS, a variety
of personal media players, a multimedia phone, at least one laptop or
palmtop computer, and an automobile navigation and entertainment system. Consequently,
TDG forecasts that the amount of digital content stored in this digital
home will grow from approximately 322 GB in 2005 to 1,933 GB in 2010.
Conclusion
While TDG estimates that there are now some 20 million digital homes
in the US (that is, households that have a broadband connection, a
home network, and multiple networked devices), less than 6% of US households
would qualify as a “well-furnished” digital home as defined
above. However, it is very plausible that by 2010 this number
will exceed 20% of US households – or approximately 22 million – and
this is using the more sophisticated version of a “well-furnished” digital
home in 2010.
There has been much recent discussion as to whether the arrival of the “digital
home” is for real or remains vacuous. Yet so many of those
who toss out opinions on this issue begin their diatribes with a fatal
mistake: the do not provide a definition of what the term “digital
home” means. Without such a definition, it is easy to straw-man
the concept for easy deconstruction – an interest intellectual
exercise but one that has no value whatsoever to the industry. In
fact, it often results in parallel discourse (that is, parties talking
past one another because they are essential speaking to two or more different
definitions of the phrase in question). This simply muddles the
discussion beyond resolution, something pundits love to do but which
has little value to those trying to create viable business models in
the space.
As understood by TDG, the “digital home” is not some futuristic
vision that has no likelihood of becoming a mass-market phenomenon. It
is already very real for some 20 million US households, and will indeed
become more common as the evolution from analog to digital technologies
continues to play out. This transition is expected to be the greatest
single factor contributing to the growth of home storage requirements
in the next five years.
