Editor's comments:- May 2014 - there are some segments in the SSD market where customers don't want the suppliers to be changing their values and obsoleting their product lines every few quarters.

In the embedded industrial markets, and in the military market in particular - customers want reliable SSD suppliers who are at the forefront of SSD architecture - that's for sure - but it works better for the customer if those suppliers are in control of their destinies to the degree that they understand upcoming technology changes, own most of their controller IP and firmware and if they can demomstrate that they are able to manage the spikey effects of chip market dynamics by roadmaps and by consistently improving new products while having a track record of long term consistent product availability.

That's one of the reasons I don't have to rewrite a new SSD profile for Microsemi every few quarters - just because of something we may have talked about recently. It seems to me - their products change - but the company remains the same.

Who's who in SSD? - by Zsolt Kerekes, editor - January 20, 2011

Microsemi is 1 of 35 companies in the 1" SSD guide, 1 of more than 50 companies in the military SSD market, 1 of more than 100 companies in the 2.5" SSD market and is also listed in these directories:- fast purge SSDs, SATA SSDs and PATA SSDs.

Microsemi's SSD technology business was initially based on technology developed by a company it acquired in 2010 called White Electronic Designs Corp (WEDC) - which was 1st listed in StorageSearch.com's SSD buyers guides in 2005. Everything the company does is related to the defense market.

SSDs and the Big Bang....

Now I don't know if you've ever seen the comedy sitcom - the Big Bang Theory?

It's about a bunch of physicist (guys) whose social skills - when it comes to encounters with other humans (in particular - girls) - are nowhere near as highly developed as you might expect from brainiacs with a deep understanding of the make up of the cosmos.

My favorite character in Big Bang is Sheldon Cooper (played by Emmy award winning actor Jim Parsons). When someone accidentally ignites Sheldon with a flippant technical comment or question - his response is a lecture - which goes on and on and on and on...

He takes physics and technology very seriously - and in some ways I'm reminded this is exactly what I do when I get invited to offer a "simple quick reply" about SSDs by some unsuspecting reader in an email. The way such questions are phrased can signal to me that the questioner may not know enough to ask the right question. Some people might call Sheldon's responses (in Big Bang) and mine (re SSDs) as somewhat obsessive when it comes to the detail.

But sometimes an obsessive compulsion to details (my positive definition of OCD) can be a good thing. And this is where we return to Microsemi's SSD products. Do you remember? we started off talking about those earlier on.

back to Microsemi's SSDs

I've been tracking the company's SSD products since 2005 - but even before they launched their 1st SSD - I anticipated they would enter the SSD market because it was a natural extension of their memory technology and the needs of their defense customers.

Last year I had some enjoyable discussions with Jack Bogdanski - Microsemi's Director of New Product Development about a range of detailed SSD technology design issues.

Even though Jack didn't answer all my detailed questions (some of the ways they've solved design problems they prefer to keep secret) I was impressed by the lengths they have gone to in some of their new SSD designs to ensure that they operate reliably under all likely operating conditions, that the data stays secure even if the SSD falls into the wrong hands, and that with customer supply cycles often extending over many years - Microsemi minimizes the risk of forced requalifications.

They design the controller software, they make their own microprocessors - which incidentally made it easier for them to ensure end-to-end data integrity - and they have more than a decade of experience with memories in "hard" defense (as opposed to "soft" industrial) applications.

One detail gives you an idea of how far the obsession with getting it right goes. When it came to the design of the architecture to manage sudden SSD power loss - realizing the importance of getting this right they applied more engineers to this than most companies deploy to entire an entire 2.5" SSD.

So - if you're in the defense market and - in particular need SSDs to fit into the tight spaces and environmental constraints of aerospace projects - and if you're looking for a long serious conversation about some minute aspect of the SSD design - which no-one else seems to take seriously - but which is a deeply sensitive issue for you - then the SSD people in Microsemi might be good to talk to.

But make sure you set aside enough time for the follow up reply. It may not be a quick one.

For more info about Microsemi take a look at the links above and Microsemi editor mentions in StorageSearch.com.

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.

"To avoid obsolescence in military systems, the design team must ensure that the die will perform at extreme temperatures and conditions. Therefore data from external silicon manufacturers isn't assumed to be dependable and instead parts are diligently characterized in sufficient quantities over a wide temperature range."
Michael Flatley, Product Application Manager, Microsemi in his blog - Solve obsolescence problems before they start (September 2013)

how fast can your SSD run backwards?
SSDs are complex devices and there's a lot of mysterious behavior which isn't fully revealed by benchmarks and vendor's product datasheets and whitepapers. Underlying all the important aspects of SSD behavior are asymmetries which arise from the intrinsic technologies and architecture inside the SSD.

Which symmetries are most important in an SSD?

That depends on your application. But knowing that these symmetries exist, what they are, and judging how your selected SSD compares will give you new insights into SSD performance, cost and reliability.

There's no such thing as - the perfect SSD - existing in the market today - but the SSD symmetry list helps you to understand where any SSD in any memory technology stands relative to the ideal.
