At $28.1 billion, overall HDD revenue is 4.1 percent higher than the $27 billion reported in 2010, but is only about half the 7 percent expansion posted by the industry in 2010.
As companies like
Hewlett-Packard, Lenovo and Dell have recently experienced with a drop in sales
of their notebook PCs, the coming of the tablet is affecting the IT business in
While sales of solid-state
NAND flash drives are
expected to boom by 400 percent over the next year
, researcher IHS iSuppli
reported May 25 that the market for hard-disk drives used in computers of all
kinds will slow down in 2011. Revenue growth this year in this sector will decelerate
dramatically compared with 2010, the researcher said.
Revenue for computer HDDs, a
category including drives for PCs and servers, is projected in 2011 to reach
$28.1 billion. But even though this is 4.1 percent higher than the $27 billion
reported in 2010, the anticipated HDD growth this year is only about half the 7
percent expansion posted by the industry last year.
Except for an expected
growth spike in 2013 that will result in a 4.5 percent expansion of the market,
IHS iSuppli said HDD revenue will continue to show ever-smaller increments of
growth in the years to come, slipping to a 3.9 percent expansion in 2012, 2.8
percent in 2014 and 2.1 percent in 2015.
By the end of 2015, global
computer HDD revenue is expected to reach $32.1 billion, the researcher said.
"The hegemony of PCs
has been usurped as consumers increasingly use tablet devices and smart phones
to browse the Internet, download and stream video and share content," said
Fang Zhang, analyst for storage systems at IHS iSuppli.
"Tablets in particular
are gobbling up consumer dollars originally intended for notebook and netbook
computers. And because tablets use flash memory for data storage, rather than
HDDs, this has translated into lost sales for the hard-drive industry."
In addition to the influence
of tablets, HDD sales have been impacted by rival storage devices such as flash
memory and solid-state drives eating into traditional hard-drive strongholds
and showing up in devices like netbook computers.
On another front, HDD
revenue growth has slowed as manufacturers introduced lower-priced drives with
higher area densities, the result of constantly improving and evolving
technology becoming more affordable over time, Zhang said.
A third factor that has
slowed HDD growth is more efficient cloud storage, IHS iSuppli said. As consumers
and corporate entities replace local storage and look to the cloud-where data
is stored through networks, either privately or publicly-HDD makers lose
another important piece of their market.
