|Greenliant promises 10
years availability of SLC |
|Editor:- September 17, 2013 - One of the
pressures which has been driving embedded SSD designers towards the kind of
which enable MLC to operate over the full
temperature operating range has been the
cost per terabyte
- but another has been the open question of whether it will be realistically
possible to guarantee sourcing SLC in the future at all - which is why some
companies like Virtium
have instead got product roadmaps which ensure that future design slots can be
filled with identical footprint SSDs which will use whatever future variations
of nand flash memory the future market is likely to offer.|
contrast to the decades old market practise of stockpiling old technology
chips for use in legacy equipment designs which are assembled much later.
These longevity assurance programs can get complicated and expensive - and I've
even heard of recent cases where SSDs are emulating 1970s vintage
floppy drives to keep
some expensive machinery running.
There are risks involved in both
these approaches (to SSD design socket continuity).
Anyway in a

senior VP, manufacturing operations - Greenliant Systems

For those in the
rugged and military SSD
markets - this type of consideration about long term product availability is
the usual way of doing business.
That's in stark contrast to the
enterprise SSD markets
- in which designers are more interested in the probability that they will be
able to get superior (faster and higher capacity) products in future
motherboard designs (so long as they are
software and interface
compatible) - rather than getting exact clones of the original devices to work
in the unchanged original motherboards.

still rule in industrial SSDs?|
|Editor:- May 3, 2012 - I've
been talking this week to a reader who has been looking for high capacity
industrial 2.5" MLC SSDs for a project which - because of where it's
used - really does need the full industrial temperature range.|
he'd been having difficulties. Anyway I suggested he look at the
directory (this page) and contact all the companies to see who did have
such a product and after a lot of work he has found some possible suppliers -
but the success rate comes out as about 20% - or 1 in 5 industrial SSD
oems actually having a useful MLC product in this category. So this is still a
part of the SSD market where SLC reigns supreme - regardless of what you hear
about in the
markets. (And the other SLC SSD bastion is
said - I think that one of the problems in finding cheaper MLC SSDs for
industrial temperature apps is that the few companies who really have the IP to
be able to design such a product from the
controller stance -
mostly pursue bigger markets - like consumer. And even if the consumer guys
do have the controller technology for extended temperature MLC - they don't
cope well with other factors - like
sudden power loss. But it's good to know that some companies can do it -
even if it's less than you would expect.
A few hours after posting the
above - I got this helfpful comment from another reader (on a different
Kindl, Managing Director at Solid State Storage Consulting in
Germany emailed me to say -
Hi Zsolt, I'd like to comment on your
today's news "SLC still rules in industrial SSDs" and your
industrial grade SSDs.
The most critical criteria for industrial clients is neither of
technological nor technical nature, but a process management topic:
industrial clients expect a true fixed BOM management by the supplier, in order
to get exactly the same product, that they had qualified for their system.
Fixed BOM has become a sales & marketing argument and is being misused. Many
suppliers allow "minor" changes, i. e. F/W updates or even dye changes
under their "fixed BOM" definition, which can cause severe integration
issues at the client's site.
Digging deeper into that subject, fixed BOM suddenly turns out to be
marketed the same as so called controlled BOM for certain suppliers, whose core
business is still the commercial or client SSD market.
In addition, it's my experience, having been in that market since
2005, that the typical life time expectation for SSD product is closer to 7+
years - at least with most German industrial clients (telecom, IPC and
industrial automation). And in many cases, you start the evaluation with a
current product generation, that will be almost EOL by the time the client has
finished his qualification.
Therefore, sharing the product roadmap and migration plan becomes
an important issue, in order to minimize re-qualification cost. This is also
becoming a major challenge as most Asian suppliers are hesitant to even talk
about current technological matters like NAND flash supplier and lithography
being used in the product as well as the NAND flash controller manufacturer.
The top tier industrial clients in Central Europe have a certain
expectation by history of the past 5-8 years and new comers don't seem to
understand the market requirements when they enter that market. At this year's
Embedded World in Nuremberg, Germany it became very obvious, that many new and "old"
suppliers (Kingston!?) want to get a decent piece of that tasty cake.
