by Zsolt Kerekes,
In the first 5 years of its history
(2006-2010) the notebook SSD market was a disappointment to SSD evangelists
like me - because integration with PCs was so bad, and most of the SSDs were
too slow or had too little capacity to be useful, while some consumer SSDs
unreliable and badly
designed. Hoping that SSDs would go away - most hard disk makers tried
to offer hybrid
drives as a stop gap - which I predicted (right from the outset) would be a
waste of space.
Now in 2013 -
the outlook for SSD notebook users is now better.
now get affordable notebook SSDs which have no compromize in capacity or
performance. And if those are above the reach of your budget - then many
SSD software companies
are now offering SSD makers auto caching software which works with vanilla SSDs
and pre-existing HDDs - which means you can use realistic ratios of flash to
magnetic storage which delivers a much better user experience than penny
pinching doomed at the design stage hybrids.

- HP offered a PCMCIA
flash disk as an alternative to a hard drive in its HP Omnibook 300. Although
not strictly speaking an SSD (because it didn't include
wear leveling) it

SSDs instead of hard drives in business notebooks.
- Google opened its
doors to developers who want to work with
Chrome OS - a new operating
system for web notebook products. Its architects are "obsessed with
speed". So they designed it to support only
flash SSDs as the
default mass storage.

The text below appeared in
Penetration Model which was published in November 2005. That
article also described the 3 other other main markets for SSDs.
most analysts and IT and electronic publications doubted that flash SSDs would
ever be affordable or viable in notebooks. I disagreed. But I was too

Running Powerpoint is critical - but so is the ability to pack a notebook PC and

manufacturers like Sony, Toshiba and Dell love this kind of customer. Her
lightweight notebooks typically cost 3 to 5 times as much as similar looking
luggables weighing 3 to 4 times as much. And she changes them every year -
because they never quite have enough performance.
In this part of the
notebook market customers pay a hefty price to get less weight and better
battery operation... And adding insult to injury - low weight notebooks also
have processor clock speeds which are typically 3 times slower than desktop
PCs (or luggable notebooks). The expensive notebooks also have slower hard
disks because that's another way manufacturers deliver longer battery life.

|upgrading old PCs with new SSDs|
Editor:- July 9, 2010 -
Old PCs with SSDs is a cautionary tale published on Denali Software's blog.
I've often told readers who asked me about this subject - that they
could be wasting their time trying to upgrade old notebooks with
SATA SSDs - because
most of the speedup benefits - if any - will be lost by the latency damping
effects of cheap and slow bridge
chips on the motherboard - and that - unlike in a server - notebooks have
precious little CPU headroom.
It's nice to see these views are
shared by the author of this article who works for an
SSD IP vendor.
what I said to a reader (Simon, in June 2010) who asked me for advice
about his Mac - which had a 4,200 RPM HDD and a lot more details supplied which
I'll skip here.
Servers have a lot of CPU and interface performance
Notebooks and PCs don't - because they are designed to meet strict
That means notebook interface
chips are cheap and slow and waste many tens of microseconds latency. That's
OK with the HDDs they
were designed to go with.
Installing a fast SATA SSD in most notebooks is a waste of money -
because most of the potential performance is lost between the CPU and the SSD in
a poor motherboard interface.
If you have a bus interface like
express card or
PCIe of some sort -
that could give better results.
All notebooks in the market today
are designed according to spreadsheets and formulas around HDD-aware chipsets.
There hasn't been any innovation in the notebook market for about 20 years. They
just follow the lead that Intel,
Gartner give them.
It's possible that a new generation of
Google OS notebooks will lead
to better chipsets for notebooks which will feed back into the Wintel and Mac
Until then the best starting place for an SSD notebook speedup is a
model which has been designed for the faster HDDs - like 7,200 RPM. In those
cases the chipsets will be slightly better.
emerged into the SSD market many years ago with a notebook SSD that was many
times faster than Samsung etc I spoke to the guys there and asked how they did
They said that instead of using standard HDD SATA chips in the SSD
they redesigned the SATA chip to make it faster for SSD. That difference made
their SSD the fastest at that time.
But if delays are already soldered into the notebook motherboard -
most advantages of an SSD will be lost.
|Problems with the Notebook
(this article was published in June 2009)
|There's a simple way to summarize my
view of the SSD Notebook / Netbook market.|
Lots of initial hype
and optimism that the market would deliver an astonishingly new product
experience to users, followed by dismay and disillusion due to a flurry of
poorly conceived, badly designed and ineptly executed products.
an analogy - think cars, gas and batteries.
cars are mostly expensive lifestyle trophies which don't solve the problem
of how to drive thousands of miles reliably or affordably - so too most SSD
notebook products have been expensive duds.
I commented on the failure
of the notebook PC market to design worthwhile SSD based products in an

so we get back to cars...
Everyone knows that the problems seen
recently in the car market didn't arise from the credit crunch and recession.
The roots go back decades. The auto market has paradoxically invested
amounts in R & D - but despite that - has failed to be innovative.
too - the pc market has developed into a lethargic mind set where the design
is driven more by spreadsheets- than by engineers.
- Intel or AMD bring out a new processor - tick the box for the next model.
The same old cycle for the past 27
- Notebook PC interfaces change in a major way only once every 10 years.
Broadband is over a decade old. USB changed from 1 to 2. Disk interfaces changed
from PATA to SATA (and
many didn't even make that change). PCMCIA changed to ExpressCard but most early
ExpressCard SSDs were slower than
- Market analysts
give you quarterly spreadsheets which predict how many models you can expect to
sell with different size screens, capacity, memory and battery life.
All these factors tend to stagnate
innovation - rather than promote it. The successful notebook makers have been
those who can recycle the same motherboard or chipsets and general IP through
multiple product generations - with little or no brainpower involved. Move the
mouse to import the new iteration of the technology - click click. Cut and
paste to next year's designs.

cycle for the past 27 years.

designers had to wake up and drink some coffee - they got burned.
hard disk makers
would create a new market segment. It did. But as StorageSearch.com predicted
(when the concept was mooted in
2005) - notebook
hybrid drives were mostly duds.
Microsoft promised notebook makers that
their Vista OS would help sell new models. That was a dud. Instead the user
experience of notebook users with Vista in the first few years was so
appallingly bad - that the lesson learned was - hang onto your old notebook as
long as possible - or if it dies - go out of your way to buy a rare new notebook
installed with XP.
The combination of the hybrid and Vista fiascos
being such recent memories - you can't blame pc notebook makers for being too
cautious about flash
Except I do blame them - because the badly designed and
poorly integrated solid state notebooks we've seen in the market in
2008 and the
first half of 2009
have tarnished the reputation of the SSD market.
And there were some
badly designed SSDs
in that mix to share some of the blame too.
I'm not sure if electric
cars are the future of personal transport - but I do hope that we'll be seeing
better designed SSD notebooks sooner rather than later.

|What's a Notebook SSD?|
|Let me begin by saying
- there's no such thing as a "notebook SSD". |
But there are
plenty of different SSDs which go into notebooks.
Confused? - You
should be. Here's a list of SSD directories - any one of which - or all of which
include manufacturers of viable notebook SSDs. Depending on the size of the
notebook, other SSD options include:-
- 1.8" SSDs
- these are usually pre-installed by the original manufacturer. Available with
upto 128GB capacity, the fastest 1.8" SATA SSDs are as fast as the 2.5"
SSDs but are much faster than hard drives.
SSDs are available pre-installed by the original manufacturer and as user
installable upgrades. In the latter case most SSDs designed for the user
upgrade market include an additional

you to create an image of the original hard drive while the new SSD is outside
Here's a warning to users! Upgrading an old hard disk
based notebook with a new 2.5" SSD can be a disappointing experience -
because the SATA / PATA
interface path on the old motherboard wastes a lot of the potential latency
gain of the SSD. Try before you buy - or carefully read
benchmarks which you can trust.
