Who's
who in SSD? - Unigen
by
Zsolt Kerekes,
editor - November 21, 2011
Unigen - is 1 of about 50
companies listed on the
1.8" SSDs page.
And
one of more than 100 companies which make either
PATA,
SATA or
SAS SSDs.
For
a few years I had thought of Unigen as being simply one of many "me-too"
SSD companies which glues a bunch of 3rd party
SSD controllers to a
bunch of memory chips, wraps them in a box, tests them according to what their
market can afford - but doesn't really add any significant SSD IP.
But today I came upon a
whitepaper
they wrote (pdf) about the subject of
dealing with
sudden power loss in SSDs. Most of what it said was standard stuff which
other people have already written about before or which has been known for
many years. (Although
Unigen's
paper does include nice pictures too.)
A different aspect of
Unigen's "EnduraCharge" technology - which I hadn't come across
before - is that SSDs which use it include a circuit which enables the host
processor to
test
the health status of the hold-up capacitors - and log the results - while
it's in the deployed system.
That was news to me - even though Unigen
had apparently published this whitepaper 5 months ago.
The reader who
contacted me - works in Unigen sales - so I asked - "Does your company
employ anyone in marketing? If so what do they do?"
Anyway - late
is better than never - when it comes to finding out that some SSD companies
aren't so me-too in their technology as I had thought. Even though there are
many more - like Unigen - in the "me-too marketing" category.
Which is to say - they don't do anywhere near enough to help potential
customers decide why they should be looking at what they do. |

In November 2009 -
Unigen announced it
will manufacture a new range of
flash SSDs using
SSD processors from SandForce.
The 2.5" SSDs will be available with
SATA or
SAS interfaces.
In
June 2011
- Unigen published a
white
paper (pdf) about its EnduraCharge Technology - (data safety features ready
for unexpected power-loss) - which describes how it deals with
sudden SSD
power loss.
Most of the stuff in there is standard - but there is
one new point I discovered.
"Unigen's enterprise SSDs are
equipped with host initiated voltage hold-up capacitor health monitoring
circuit. The host issues a special "Test Hold-up Cap" SCT
diagnostic command to measure the health status of the hold-up capacitor. After
completion of the "Test Hold-up Cap" command, the host will retrieve
the hold-up capacitor attributes of the most recent test result. The host can
also retrieve all past history hold-up capacitor test results."
In
June 2014
- Unigen entered the
M.2 SSD market. |

| Unigen enters M.2 SSD
market
|
Editor:- June 3, 2014 - Unigen today
announced SLC or MLC
NAND flash based
M.2 SATA III SSDs in
densities ranging from 16GB- 256GB.
These small form factor flash
modules are used for high reliability storage of critical code and data, in
space-constrained embedded, industrial, gaming and networking applications.
They are available in both commercial and
industrial
temperature ranges. | | |

hold up
capacitors in 2.5" military SSDs
to be or not to be? |
Editor:- March 27, 2015 -
zero
to three seconds are 2 numbers which demonstrate some of the
extreme diversity in
SSD design. My examples here being the hold up times inside 2 current
models of 2.5" SATA SSDs designed for the
military market.
- One from Microsemi
(HQ in Aliso Viejo, CA, USA).
- And the other is from Solidata (HQ in
Shenzhen, China).
I've touched on this kind of architectural design
difference many times before in earlier articles. But every time I revisit this
vast topic with fresh examples - I learn something new.
