SSDs - boring right?|
|Editor:- June 13, 2017 - For the past 11 years
one of the safest assumptions you could make about the SSD market was that if
you were looking for excitement and big revenue growth opportunities then the
last place you should be looking was the industrial SSD market.|
an important part of
history is that it started in industrial applications and only became
mainstream and interesting - from a
point of view - when flash SSD designers turned their gaze towards other
directions like the consumer
In fact a good rule of thumb in the exciting days of
disruptive change in the SSD market during 2004 to 2016 was that if you knew the
capabilities of leading edge industrial SSD products in any one year the
picture was probably the same the next year too.
customers - who were concerned about whether they would still be able to get
the same locked BOM
SSD 5 to 10 years after choosing it for their long lived design - the
reassuringly boring predictability and calm, careful approach to new
technology adoption in industrial SSD companies was widely regarded as a virtue
compared to other brasher markets.
But there are many reasons to
believe that the industrial SSD market will soon become a new attention seeking
cauldron of innovation and architecture too.
I describe some of the
indicators which brought me to this surprising conclusion in a new blog -
your grandfather's industrial SSD market - on .

Efficiency as internecine
SSD competitive advantage
|In the year 2000 no one
caught a cold from the Y2K bug - but 3 things did happen which would shape
enterprise server performance for the next 16 years.|
1 - hard drives
reached the latency limit set by waiting for a 15K RPM rotating platter (they
never got faster)
2 - 64 bit processor clock speeds reached almost
their maximum clock speeds (they got more cores but the cores didn't get faster)
- in the RAM market - the fastest server motherboard memory latencies in 2000
were very similar to what they are today (in 2016)
We all know that
SSDs came to the rescue of latency constrained advances in computing which had
been stalled by (1) and (2) above.
With some help from software the
next target is (3).
Why's DRAM so bad?
Most of us thought
that DRAM was the gold standard for latency you can rely on (unlike that cheap
flipperty gibbet flash).

that it will be sampling the industrys first 11.5x13mm NVMe BGA SSDs which
support Boot Partitions and the Host Memory Buffer features of NVMe rev 1.3

(DRAM-less) PCIe 3.0x2 SSDs - aimed at the
and being shown in the next few days at the

available in capacities from 60GB to 480GB (64-layer 3D NAND ) and use the
88NV1160 controller from Marvell.
As the worlds leading Mini SDP SATA DRAM-less SSD module provider,
Longsys has once again made a unique contribution to the storage industry by
pioneering the integration of Marvells DRAM-less SSD controller 88NV1160 and the
new 64-layer 3D NAND into a 11.5mmX13mm BGA package, said Zhixiong Li,
CTO of Longsys.

applications for NVMe SSDs on a chip in the consumer market I think the
widespread availability of such devices in 2018 could create new opportunities
for disruptive "high availability" BGA array architectures in

Marvell's new skinny controller will enable BGA PCIe SSDs
December 9, 2014 - 3 of the most significant differentiating factors in
flash SSD control
In the past year or
so - we've seen a few companies - whose controller products have long been
distinctly at one end of each of the above categories - introduce new designs
which can operate in the other. This is a competitive response to the
realization that any single architecture is better suited for some applications
rather than others and no single design set is best for all markets.

SF-3700 - launched last year - added big controller features as an option to
its legacy minimalist small architecture configuration mode. And before that -
the intrinsically skinny (cache) SF family added support for optional external
This week Marvell - whose
controllers have always until now been firmly in the regular RAM flash cache
it now has IP which enables it to play a significant part in skinny RAM flash
cache designs with 2 new controllers:-
- Marvell's 88NV1140 - aimed at
NVMe PCIe Gen3x1 SSDs
- can work with 15/16nm TLC and 3D NAND and needing no external DRAM -
will simplify the design of smaller form factors including the capability of
BGA PCIe SSDs.
- Marvell's 88NV1120 - aimed at the embedded
SATA SSD market which
supports DevSlp - won't by itself create new markets - but will - due to its
small footprint and memory support - lower the cost barriers for greater
adoption of small SATA SSDs in traditional embedded markets.

Greenliant promises 10 years market availability of SLC
Editor:- September 17, 2013 - One of the pressures which
has been driving embedded SSD designers towards the kind of elaborate
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).

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.

|Toshiba Introduces World's Smallest Hard
7, 2004 - Toshiba
today announced the development of a 0.85-inch hard disk drive, the first drive
to deliver multi-gigabyte storage in a
sub-one-inch form factor.
Expected to be available in 2GB and 4GB capacities, Toshiba will start sampling
the new drive in summer 2004, with mass production to begin in late 2004
Measuring only a quarter of the size of Toshiba's 1.8-inch drive, the 0.85-inch
HDD is expected to boost the functionality of a new generation of products,
including mobile phones, digital audio players, PDAs, digital still cameras,
camcorders and external storage devices.
Toshiba initially plans to
introduce capacities of 2GB and 4GB, and anticipates achievement of even higher
densities in the 0.85-inch form factor.
A prototype of the 0.85-inch
HDD will be shown at Toshiba's booth (#12214) on the CES show floor January
in January 2011 - over 30 manufacturers now market
drives in 1" and
smaller form factors - although for economic reasons these are mostly SSDs.
