I had been wanting to learn more about the internal
thinking in Innodisk for some time- as I could see in glimpses of technology
which appeared in their products - that there was evidence of original thinking
there - and significant investment in unique controller IP.
know the details and wanted to learn more.
So I requested an SSD
conversation with Charles
Tsai, Senior Director - Innodisk - and we spoke for about an hour on
topics like new ways to design enterprise flash arrays and about new ways to
make industrial SSDs better which borrow concepts from cloud architecture.
led me to re-evaluate - not only my assessment of the company - but also change
my opinion of what they were doing in the rackmount SSD market too.
had been very dismissive in my comments about - Innodisk's FlexiArray - when
the company launched that product in
November 2013 - as
you can see from my archive comments in the original news story.
that was one of the first things I brought up in my conversation.

why I changed my mind from a negative to a positive opinion) in the article -

company is part of a new set of trendsetters in the SSD market who - learning
from the experience of many customers (and in particular big cloud / web
users) are now starting to partition their flash management functions in a more
powerful and flexible
way - so that the responsibility for some actions is decided at a higher level
in the firmware - rather than simply dumping everything onto the controller
inside the drive - which doesn't have the same visibility of what might be
happening in other SSDs - or upstream in the host requests.

InnoDisk announced the
world's physically smallest SATA SSD - the SATADOM - measuring 39mm by 20.5mm

- C.C. Wu -
Director - InnoDisk -
presented a paper -
Comparisons of SLC, MLC and eMLC (pdf) - at the Flash Memory Summit. Wu's
paper - which compares data for several generations and brands of SLC flash -
confirms what some SSD makers had been telling me since the early 2000s (as
reported in my SSD
endurance article) - which is to say that SLC in reality has often been 5x
to 20x better than specified in the chip memory datasheets. The same is
not true for MLC - however - which presents greater risks of data loss when
suddenly turned off - which in turn requires better
architecture to recover and automatcially heal the data.
In March 2013 -
it will ship industrial
SATA SSDs in Q3 using
its iSLCT technology - which repurposes MLC as emulated SLC to get 30k write
from 3k standard cells.

iSLCT repurposes the 4 states of classic
MLC memory into 2 virtual states (with better signal integrity) effectively
emulating SLC in MLC.
This delivers 10x better endurance than MLC
(30K from "3K" MLC), faster write performance (nearly 2x as fast as
MLC and 85% of SLC speed - at competing geometries) and lower cost than using
SLC to achieve the same capacity (in current and projected market conditions).
Editor's comments:- I mentioned this technique several years
ago in a spoof SSD story - but what was once SSD fiction has become market
reality due to the divergent market
prices of different
types of flash memory.

|How adaptive is the SSD
behavior to changes within itself? |
All SSDs rely on processing data
about the quality of the memory as part of their normal data integrity
They wouldn't work without it.
But some companies have SSD IP sets in which knowledge about different
parts of the SSD can be optimized and fed back to control and enhance SSD
functionality over and beyond the standard accepted SSD function block
The degree to which this passing of the intelligence
(regarding the state of past and future anticipatable data flows, priorities
of the application and the flash array's own readiness and healthiness
condition) can impact behavior in other parts of the SSD - is what I call
adaptive intelligence flow symmetry.
