| leading the way to the
new storage frontier
Lots of companies design and sell 2.5" SSDs. You can scroll
down this page to see who they are below. So
where do you begin?|
One simple way to divide the market is -
it's those with SandForce
controllers inside - and then everyone else.
But that would be
OK another way is to narrow things down is to look at
If you need the
fastest SSDs in the
2.5" form factor - take a look at
SAS SSDs and
2.5" PCIe SSDs.
Do you mean rugged
rugged for true military
deployments with fast secure data purge?
what about a 2.5"
SSD for notebooks?
market has got more size options than that.
what about a 2.5"
SSD with a particular interface?
Did you mean
parallel SCSI SSDs?
(yup new designs are still available to plug into legacy hard disk slots) and
- I almost forgot to mention them because they are going out of fashion -
fibre-channel SSDs. And
since the idea was first demonstrated in
PCIe has been creeping
off cards and modules and into new models of
2.5" PCIe SSDs.
about that old SLC versus MLC thing?
It still matters
in some cases -
but not in all.
What about cheap? - who makes the cheapest
article which shows how
prices have dropped in the past 10 years - and why I can't answer that
question. "SSD" is not enough enough information. What's in and what's
left out of the design - makes a big difference to the price. And you can't
trust consumer SSD
makers to make these decisions for you for a
variety of reasons.
are the top SSD companies which really matter?
I thought you were
never going to ask that. Here's what
millions of other SSD
why does the SSD market look so complicated?
it is complicated.
I've only been talking about 2.5" SSDs
here. If you include all the other sizes - I currently track over 300 SSD makers
- and that could rise to
over 1,000 in a
handful of years time...
It's all about the size of the market
opportunity and how
the market will grow in the future.
SSD companies genuinely
disagree about the best way to design SSDs and where to put them.
market will get more complicated before it gets any simpler.

8TB 2.5" PCIe SSDs sampling soon from Novachips|
|Editor:- March 4, 2015 - Are you interested in a
8TB (15mm height) PCIe Gen2 x4 SSD (pdf) with a single controller developed
was an email I got recently from Sean Oh, based in
Kronberg, Germany, (firstname.lastname@example.org) who is the sales representative for
these products in Europe.
What would you say? I did the same. After
reading up the info he attached (there's a
too) I asked some questions about availability. Here's what Sean said.
- The working engineering samples have been available since last year.
- The 1st customer sample comes out in the next 30 days.
Editor's comments:- part of this story has its roots in a news
story from May 2007
- when a company called MOSAID was talking about a new, light capacitive load,
ring based, flash memory topology called HLNAND. To make it work they needed a
controller. Novachips collaborated on the design and recently acquired the
assets and patents.
- We plan to start a mass production in 2nd half of this year.

|SSD Pricing -
where does all the money go?|
|SSDs are among the most
expensive (and complex) computer hardware products you will ever buy and
understanding the factors which determine SSD costs is often a confusing
and irritating process... ...which is not made any easier when market prices
for apparently identical capacity SSDs can vary more than 100x to 1!
|| Why is that? There are
good reasons for these cost differences. But more expensive isn't always better
for you. To find out what goes into the price - and whether you need it - ...read the article |
