Introducing the flash SSD market..........
by Zsolt Kerekes, editor

Flash based SSDs use non volatile semiconductor technology to store data, and do not need any batteries to retain data when they are unpowered.

Because they have no moving parts they are inherently more reliable than hard disks and use less operating power. Flash SSDs can operate in hostile environments including industrial, military and even outer space applications.

Flash SSDs have been commercially available for a very long time.

For example - in 1999 - BiTMICRO launched an 18GB 3.5" flash SSD.

In the early 2000s - low capacity flash SSDs such as the DiskOnChip opened new markets in intelligent phones - and also started to replace miniature hard drives.

Prior to 2005 - high capacity flash SSDs were mostly used in rugged embedded applications in which their wide temperature operating range and greater reliability (compared to hard drives) made SSDs the only viable choices.

In 2006 - flash SSDs started to appear in mass market notebooks as direct replacements for HDDs.

In 2007 - revolutions in flash SSD controller architecture - enabled some flash SSD makers to reach IOPS performance levels previously only achieved by much more expensive RAM SSDs - while managing endurance within a tolerable product life.

2010 - Year of the SSD market bubble - was the 1st year that the SSD market reached billions of dollars. (2 to be precise.)

The SSD market is growing fast (high double digits or low triple digit percentage revenue growth per year) and despite significant problems which need to be overcome in some areas of the the notebook and server markets - it has the potential to become a $10 billion / year market (a potential which was the 1st market data source to identify in 2003.)

But SSD revenue won't stop there. The big picture shows it eventually exceeding the peak size of the HDD market by the end of this decade.

Today in 2011 there are nearly 300 known manufacturers of flash SSDs, and flash SSD controllers.

Instead of presenting you with a long alphabetic list of companies (which I used to do when the market was smaller) you can find flash SSD companies and content on this site using this prepopulated search link - which you can adapt to your own requirements by adding or deleting terms.

For SSD market size information take a look at the articles and links in the SSD market research directory.

the Problem with Write IOPS

the "play it again Sam" syndrome
Editor:- Flash SSD "random write IOPS" are now similar to "read IOPS" in many of the fastest SSDs.

So why are they such a poor predictor of application performance?

And why are users still buying RAM SSDs which cost 9x more than SLC? - even when the IOPS specs look similar.
the problem with flash SSD  write IOPS This article tells you why the specs got faster - but the applications didn't. And why competing SSDs with apparently identical benchmark results can perform completely differently. the article

this way to the Petabyte SSD
In 2016 there will be just 3 types of SSD in the datacenter.

One of them doesn't exist yet - the bulk storage SSD.

It will replace the last remaining strongholds of hard drives in the datacenter due to its unique combination of characteristics, low running costs and operational advantages.
click to read the article -  reaching for the petabyte SSD - not as scary as you may think ... The new model of the datacenter - how we get from here to there - and the technical problems which will need to be solved - are just some of the ideas explored in this visionary article.

Who makes the fastest SSDs?

Speed isn't everything, and it comes at a price.........
But if you do need the speediest SSD (chip, card, module or rackmount) then wading through the web sites of hundreds of SSD oems to shortlist products slows you down.

And the SSD search problem will get even worse as we head towards a market with over 1,000 SSD oems.

Fast Purge flash SSDs
The need for fast and secure data erase - in which vital parts of a flash SSD or its data are destroyed in seconds - has always been a requirement in military projects.
Fast Purge flash SSDs directory & articles Although many industrial SSD vendors offer products with extended "rugged" operating environment capabilities - and even notebooks SSDs come with encryption - it's the availability of fast data purge which differentiates "truly secure" SSDs which can be deployed in sensitive applications.
SSD power down management
Why should you care what happens in an SSD when the power goes down?

This important design feature - which barely rates a mention in most SSD datasheets and press releases - has a strong impact on SSD data integrity and operational reliability.

This article will help you understand why some SSDs which (work perfectly well in one type of application) might fail in others... even when the changes in the operational environment appear to be negligible.
