|Software is key to SSD innovation - says
Editor:- June 29, 2012 -
fibre-channel are some of
the innovations discussed in a
blog by Jeff Sosa,
Director of Product Management,
who poses the question - is flash storage an incremental or a radical
Sosa's article goes on to say - "The 'radical'
innovation in the host-attached flash storage marketplace today comes from
products that not only access flash through a PCIe connection, but also bypass
storage protocols to drive new levels of performance and enable new
functionality not previously imagined." ...read
SSD - Legacy vs New
Important update to DSP IP in SSD ECC article
June 28, 2012 - after publishing my article about
techniques inside MLC SSDs - I realized that some of you would want to know
a lot more about the subject than I know or have time to write about about.
So yesterday I asked Gregory Wong founder of
Insights if he could add anything for our readers - and also which of
his many reports would be appropriate for someone who needs to dive more deeply
into this subject?
You can see what he said in this important update

Seagate chooses DensBits for flash care SSD roadmap
June 25, 2012 - Seagate
announced today it will use DensBits's flash care
technology in the design of forthcoming consumer and enterprise SSDs.
has also made an equity investment in DensBits.
comments:- I've already written more than enough about about this technology
trend recently on the home page.
As DensBits told us a few months ago - their business plan is work
with companies which sell complete SSDs - instead of licensing their technology
to other controller
makers. DensBits's technology spans the widest spectrum of adaptive DSP flash
SSD applications from consumer and industrial to fast-enough enterprise SSDs.
If Seagate leverages DensBits's flash technology successfully - the
result will be tougher competition for companies like
SanDisk in the
consumer SSD market
and tougher competition for
SMART in the
enterprise SSD market.
Seagate's technology deal with DensBits is
probably the most significant positive step Seagate has ever taken to establish
a leadership position in the SSD market.
However, due to the
complexity of integrating the multi-dimensional IP from DensBits into real
working SSD products - it could take another few quarters before we see a
market impact. (It's not as simple as integrating a new SSD controller - but on
the other hand - once the design work is done - the degrees of freedom to
optimize products which this technology gives to SSD designers is awesome.)
just another speedup Oracle with SSDs story
June 25, 2012 - If you're into accelerating Oracle in analytics apps with SSDs -
story published today by Nimbus has some
market growth and speedup percentages you might be interested in.
liked this quote from Nimbus's CEO, Thomas Isakovich
- "DBA's have long struggled with disk arrays, going through all sorts of
configuration complexity in hopes of reducing latency by a millisecond or two.
As this win demonstrates, organizations that deploy Nimbus flash memory systems
can eliminate decades of disk array tuning challenges and supercharge database
performance, increasing revenue opportunities and improving quality of service."
comments:- that's a nice cheer leading story about enterprise SSDs on which
to start the week - but I would caution you to reread it with this emphasis - "flash
memory systems can eliminate decades of disk array tuning
aren't going to disappear when all storage is solid state. And you will still
find many Oracle apps which don't speedup just because you stick an SSD next to
the server / HDD storage.
You'll still need to use your brains to
control where you spend your performance budget.
Tech Report article on consumer SSD prices
June 22, 2012 - a recent article in Tech Report reported
the price per GB of consumer SSDs as being mostly between $1 and $2 across a
range of popular models.
Editor:- I usually regard this type
of article as banal and too single-dimensional - so why should you look at it?
if you're interested in getting an idea of what's happening in the minds of
potential SSD consumers - the article has attracted
Some of Tech Report's readers are pretty
impressive and punchy at writing headlines which describe what their own
decision tipping points would be.
