founded in Ireland in
2013 when the
ADAPT project was spun out of the National Digital Research Centre in Ireland.
The technology is the result of
13 years' work
(pdf) on flash memory endurance by Joe Sullivan
and Conor Ryan.
SSDs using non-volatile memory are rapidly taking over from hard disks. However
SSDs wear out and this is holding back their complete replacement of hard disks.
NVMdurance' trials with leading manufacturers have proven to significantly
extend the life of SSDs. NVMdurance has offices in Limerick, Ireland and San
Jose, California. |

On a handful of occasions in more than
writing about the SSD market I've spoken to companies which I known
instinctively would change the way that the whole market thinks about itself.
NVMdurance is one of those companies.
While we have seen many
companies in the past 5 years telling us about the different ways in which their
technologies can leverage the mysterious
in an SSD controller
context - most of those have leveraged combinations of techniques such as
adaptive R/W pulse modication,
and big controller
application or array awareness which become so closely tied to a particular
product line or application space that the benefits derived from each element in
the mix cannot be easily or quickly extracted and migrated to other
NVMdurance has created a multigenerational and
sustainable characterization methodology which - when applied to any
kind of flash -and with the use of a lightweight firmware manager - enables
endurance to be restated with a useful magnification effect (of x7 to x10)
which is accomplished without the use of processor intensive DSP techniques -
but which can be used as a restated foundation level of endurance which can
then be used in conjunction with other proprietary endurance stretching
A simple way to state the market effect is like this.
MLC or TLC nand flash - whether 2D or 3D - can now be thought of as having 2
- the standard model rating of endurance, and also
Most of the
software based tricks which can be usefully applied to standard endurance can
still be used (if required) taking the improved NVMdurance base level of
endurance as the new starting point.
- the improved NVMdurance model rating of endurance (metascale advised,
life-cycle fitted, virtually hardened flash endurance).
Therefore what you have - in
effect - is a much greater pool of memory types.
SSD designers in
the NVMdurance era now have greater freedom to use simpler, lower power
controllers and cheaper (worse standard endurance flash) to get
DWPD ratings which
hitherto would have required more power hungry controllers or more expensive
memory (or rare inhouse flash controller talent).
Part of the
NVMdurance technology story is evolutionary but another part (the business
model and the disruptive market impact of its brute force systematic offline
characterization techniques) is revolutionary. I'll be saying more about those
in a follow up
