  • editor's comments:- November 2011 - among other things Unigen offers flash SSDs in 1.8" (& MO-297 ) and 2.5" form factors using a variety of SSD controllers including Indilinx and SandForce.

    Unigen offers SSDs with SAS, SATA and PATA interfaces. If you click any of these preceding links you'll see's directories which list other companies in these sub markets.
selected Unigen milestones - from SSD Market History.

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."

Who's who in SSD?
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.

I currently talk to more than 300 makers of SSDs and another 100 or so companies which are closely enmeshed around the SSD ecosphere - which are all profiled here on the mouse site.

I learn about new SSD companies every day, including many in stealth mode. If you're interested in the growing big picture of the SSD market canvass - StorageSearch will help you along the way. Many SSD company CEOs read our site too - and say they value our thought leading SSD content - even when we say something that's not always comfortable to hear. I hope you'll find it it useful too.
