The SATA SSD market is important - because
by offering a like for like comparison with hard drives - in form factors like
3.5", 2.5" etc it showed server makers that the days of HDDs were
numbered.
I often get asked - What's that number? How many days left?
It's not
that simple. The answer depends on your business application, the cost
benefits of performance, electrical power, reliability etc. Depending what
market you're in - SSDs are already the most economic option - or will be at
sometime before 2015. For a variety of SSD future views see the
SSD analysts page.
In 2004 - when
StorageSearch.com conducted the
industry's first
SSD Buyer Preferences
Survey53% said that SATA compatible SSDs would suit their
applications best. At that time there were no SATA SSDs in the market.
SSD oems took heed of these results and by the end of 2005 there
were 4 SSD manufacturers offering SATA.
This had grown to 11 at the
end of 2006 and rapidly accelerated in the following years to 30+ companies by
the end of 2008
and 80+ companies by the 3rd quarter of 2010.
Since
2012 - new companies
have been entering the SATA SSD market every day - and I no longer list them
all here - because mostly they are me-too - with some rare exceptions.
BTW
- 2007
was the 1st time that SATA SSDs left HDDs in the dust when it came to
performance - at the same
time as
2.5" SSDs reached
capacity parity with
hard drives.
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.
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 destructive data purge which differentiates "truly
secure" SSDs which can be deployed in sensitive applications.
Who
makes these SSDs? How do they work? And what are the characteristics and
limitations of the various methods used? Click on the link above to find out

First you learned about SLC
(good flash).
Then you learned about MLC (naughty
flash when it played in the enterprise - but good enough for the short
attention span of consumers).
Then MLC SSDs learned how to be good.
Now some MLC is much nicer than others. - When it's preceded by an "e"
(extra-good). But it costs more.
But other people say you don't need
the expensive "e" - because their controllers empathize better
with naughty flash. (They really care about naughty flash being sent to bad
block jail too soon.)
