|WD acquires Hitachi GST|
March 7, 2011 -
today announced it will acquire Hitachi GST in a cash
and stock transaction valued at approximately $4.3 billion.
resulting company will retain the Western Digital name and remain headquartered
in Irvine, California. John Coyne will remain CEO of WD, Tim Leyden
COO and Wolfgang Nickl CFO. Steve Milligan, president and CEO of
Hitachi GST, will join WD at closing as president, reporting to John Coyne.
Editor's comments:- This will confirm WD as the
largest manufacturer of
hard drives (a position
it has been inching towards organically) and could also have a significant
impact on the company's SSD market presence too. The acquisition (expected to
close in the September quarter) shows a lot of confidence in the medium term
future of the hard disk market. Although hard drives are the primary
motivation for this acquisition - the result will also be a bigger player in
the emerging SSD market too.
WD has had good visibility into the SSD
market through its earlier acquired
business whch has been shipping SSDs since 2004. Hitachi GST has been a
laggard in the SSD market - with its most significant products still in the "coming
soon" / being qualified category.
In today's conference call
today we heard that both companies expect that hard drives will continue to
be the main devices which store high capacity digital content for the forseeable
This view is completely compatible with my own previous
published predictions about SSD growth and SSD market penetration. The devil
is in the details - and the picture is complicated.

I expect that a new class of bulk storage SSDs will have lower running costs
than high capacity HDDs in datacenter apps. And as I've said many times the
consumer entertainment market has different economics in which HDDs will stay
In my 2007 article
How Solid is
Hard Disk's Future? I explained why the HDD market would continue to grow
and probably not peak until 2011. In that article I also gave a simple rule of
thumb - which was - "HDDs will survive in applications where the average
size of disk installed is an order of magnitude above the most commonly
available shipped SSD." What that means in today's market is that 250GB
SSDs can coexist in the same market as 3TB hard drives - because they don't
compete for the same application slots.
drives in notebooks?
I've always said since the very first time the idea was mentioned on these pages
(April 2005) - I
think they won't provide a good sustainable solution and are a waste of space.
It doesn't stop manufacturers trying - but each new hybrid notebook SSD so far
has been the triumph of hope over experience.
Do I think SSDs will
eventually replace HDDs? Yes - no doubt about it. But there's a long way for
the hard drive market to run between now and the picture
describe in 2020 when - "the only spinning devices in the storage
cabinets will be the cooling fans".

Intel publishes new standard to increase efficiency of PCIe SSDs
March 1, 2011 - Intel
published version 1.0 of a new proprietary standard for designers of
PCIe SSDs in systems
which use Intel processors - the
NVM Express Optimized PCI
Express SSD Interface.
The interface efficiently supports
multi-core by ensuring thread(s) may run on each core with its own queue &
interrupt without any locks required. For enterprise class solutions, there is
support for end-to-end data protection, security & encryption capabilities,
as well as robust error reporting and management capabilities.
says that more than 70 companies have contributed to the standard - which will
make it easier to write software drivers which support multiple vendors. The
new standard will also make it easier for oems to adopt new SSD products from
alternative vendors which implement a consistent feature set.
