Coming of Age for Solid
State Disks
Although manufacturers in the industrial controls
market, like
Square
D and AB were using
rewritable user removable non volatile solid state storage as early as the
1970s, it wasn't till much later that the
solid state
disk market evolved into a form which we would recognise today. For most
of its early life, this technology remained an open secret - mainly used in
embedded systems in military applications, or in high performance computer
research labs.
There were many false starts with Non Volatile
semiconductor technologies which didn't survive.
In the late 1970s -
silicon nitride EAROMs (electrically alterable ROMs) were marketed by a
company called General Instruments. Unfortunately after about 3 years - it
became clear that the extrapolated data life of 10 years wouldn't be achieved in
practise. As a result this product was dropped by users and didn't survive in
the market.
1976 -
Dataram sold an SSD
called BULK CORE which attached to minicomputers from
Modular Computer Systems and
emulated hard disks made by DEC and Data General. Each chassis held
8x 256k x 18
RAM modules and had a capacity of 2 megabytes.
... ...32 years later:- (in
October 2008)
Dataram re-entered the SSD market with its
acquisition of
Cenatek.
In
1978 - a gigabyte of RAM SSD would have cost $1 million.
Texas Memory Systems
introduced a 16 kilobyte RAM-based solid state disk system designed to
accelerate field seismic data acquisition for oil companies.
1980
- Dataram marketed
an updated version of their
BULK CORE SSD
for use with
DEC PDP-11 and
Data General minis.
In the early 1980s - Intel's 1M bit bubble memory created
a lot excitement as a new non volatile solid state memory technology. Intel
shipped design kits and boards to developers using this technology - which was
positioned as a solid state floppy disk. But it failed to be scalable or cost
effective. Intel spun off the magnetic division in 1987 to
Memtech (who later made
flash SSDs) but bubble memory dropped into oblivion.
1985 -
Adtron founded.
1985
-
Curtis introduced the
ROMDISK, the first SSD for the original
IBM PC.
In
1987
EMC
introduced SSD storage for the mini-computer market, which was the
hottest part of the server market at that time. EMC's SSDs were 20x faster
than the then available hard disks. But market forces and losses led to EMC
exiting the "memory enhancement" business soon after.
... ...21 years later:- EMC
re-entered
the SSD market in January 2008 - with arrays populated by
flash SSDs from
STEC. This time the
market was hungry for this type of solution.
1988 -
SanDisk founded.
In
1990 -
NEC marketed 5.25"
SCSI SSDs using internal battery backed
RAM.
In 1991
Digital
Equipment Corp marketed the
EZ5x
family of Solid State Disk accelerators. However,
SPARC servers from Sun
already ran 2 to 3 times faster than DEC's servers at about half the price of
DEC's
Vax
servers (without needing SSDs). SSDs did not save DEC's server business.
Faster processors might have done. DEC's gamble on denser ECL chip technology
- with its
Trilogy
venture - was an expensive failure.
In 1993 -
Solid Data Systems was
founded.
In 1994 -
StorageTek
documents
mention a RAM SSD product called Arctic Fox which had been developed by a
company called Amperif Corp,
acquired
in 1993.
In 1995 - our
SPARC Directory listed 2
SSD products aimed at the Sun server market.
- T8000 - was an 80MB, 10MBps SSD on a single slot
SBus card,
made by Colorado based CERAM. Units in multiple slots could be chained to appear
as a single SSD upto 960M. Performance was 2,000 IOPs.
- SAM-2000 was a rackmount SSD upto 8GB, with 500MBps internal bandwidth-
made by Texas Memory
Systems. The transfer rate through the SBus adapter was 22MBps. Other bus
interfaces included VMEbus
and
HIPPI.
In
1996 - ATTO
Technology maketed the
SiliconDisk
II. It was a 5.25" form factor SCSI-3 interface RAM SSD with 64MB
to 1.6GB capacity. Throughput was 80MB/s, and performance was 22,000 IOPS.
In
1997 - a
white paper by Peripheral Concepts listed the main SSD vendors as:-
Quantum,
Imperial Technology,
SEEK Systems, and
Solid Data Systems.
In
1998 - STORAGEsearch.com published an
online directory of solid state
disk vendors - in which Megabyte
was shown chipping away at a rock - which remains the current site metaphor
used for general SSDs.
In 1999 -
BiTMICRO launched an
18GB 3.5"
flash SSD.
In
November 1999 - the number of market active
SSD manufacturers listed on
STORAGEsearch.com had reached 11.
In
January 2000 - after 8 years featuring editorial about SSDs in our
various publications,
Curtis became our first
SSD advertiser.
In June 2001 -
Adtron shipped the
world's highest capacity 3.5"
flash SSD. The
S35PC had 14 gigabytes capacity and cost $42,000.
In Q1 2001 -
SSDs were the 18th most popular subject with our readers.
In October
2001 - the number of market active
SSD manufacturers listed on
STORAGEsearch.com had reached 21.
2002 - terabyte SSDs become commercially available
In
Q1 2002 - SSDs were 4th most popular subject with our readers.
In
November 2002 -
Bill
Gates, talking about Tablet PC's said:- "There are also a lot of
peripherals that need to improve here. ...Eventually even the so-called solid
state disks will come along and not only will we have the mechanical disks going
down to 1.8 inch but some kind of solid state disk in the next three to four
years will be part of different Tablet PCs."
In Q4 2002 -
we ran our first ad for a NAS SSD. It was the
NAS-168F from
IEI.
In
Q1 2003 - SSDs were 2nd most popular subject with our readers..
In
February 2003
- Competitors Texas
Memory Systems and Imperial
Technology announced the world's first terabyte class SSD systems.
The
Tera-RamSan, from
TMS, provided 2 million IOPS, a 1024 gigabyte capacity, and 128 2-Gbit Fibre
Channel links. It required 2 racks and 5000 watts.
The MegaRam-10000, from Imperial, cost $2 million for a 1TB
subsystem with 48 fibre channel ports.
In
Q2 2003 - SSDs were #1 most popular subject with our readers.. That's
why we researched and compiled the first
Solid
State Disks Buyers Guide in July 2003 which collected together in one
convenient document pricing information from across the whole SSD industry.
It covered the range of budgets from under $50 up to $2 million and everything
in between.
StorageSearch.com researches what SSD buyers want
In September
2004 - BiTMICRO
announced it was developing iSCSI
SSDs. But due to the hyped iSCSI market in 2004 being 10x smaller than
analyst predictions - this product was quietly shelved.
In Q3 2004
- a solid state disk manufacturer,
Texas Memory Systems,
became the #1 company profile viewed by our readers (out of more than 1,000
storage company profiles in September 2004). We also disclosed that the
Solid state disks directory
(still at #1) got 42% more pageviews than the year ago period.
In
October 2004 - STORAGEsearch opened the
SSD Survey a 3 month
major market research study to learn more about SSD buyer preferences,
applications and attitudes. Results from the survey were published in articles
in 2005 and detailed findings helped SSD vendors understand the needs of
buyers better, and helped them develop marketing plans which worked around the
prevailing disinhibitors to product take-up and leverage the enablers cited by
buyers in the survey.
Also in October 2004 -
BiTMICRO Networks
shipped the world's first Ultra320 SCSI flash solid state disk.
In
November 2004 - STORAGEsearch published the 2nd annual
Solid
State Disks Buyers Guide. This listed every type of SSD available in the
market by interface type and form factor. It also included a summary of major
developments in the SSD market in the preceding year.
In December
2004 - It was revealed that Solid State Disks were the Product Category of
the Year 2004 on STORAGEsearch.com based on reader pageviews. The Solid State
Disk page was the #1 category (out of more than 70 vertical storage subjects)
viewed by readers for 44 of the first 50 weeks in 2004. In previous years - the
product category of the year in 2002 and 2003 (2 years running) was SATA. Three
of the world's
fastest
growing storage companies in 2004:- (M-Systems, SimpleTech and Texas Memory
Systems) were solid state disks manufacturers.
2005 - Samsung declares SSDs a strategic market
In January 2005 - STORAGEsearch disclosed results of the
SSD Survey to
strategic oem customers. The results included buyer preferences for form factor
and interface, budgetary data and factors which would make it easier for SSD
vendors to do more business in future. Selected extracts from the survey results
also appeared in articles and editorial.
In March 2005 -
SiliconSystems
announced that Bell
Microproducts would distribute its SSD products in North America. This would
greatly simplify the access to this technology for thousands of systems
integrators and oems.
In March 2005 - 5 out of the top 10
company profiles viewed by STORAGEsearch.com readers in March were SSD Makers
(out of more than 1,000 storage company profiles). Site readership grew 6%
compared to the year ago period and pageviews grew by 25%.
In April 2005 -
Texas Memory Systems
offered the world's first performance related guarantees for SSD products. That
they would outperform any competing storage system, or meet the customer's
agreed application speedup expectation - or the customer would get their monry
back. This approach was founded on market research data from
STORAGEsearch.com's Q405 SSD User Survey - which said that users would be more
likely to try SSD systems if vendors offered such guarantees.
Also in
April 2005 -
Solid Access
Technologies made the first SSD with a
Serial Attached SCSI
interface.
In May 2005 -
Samsung Electronics
announced it was entering the SSD market with 1.8" and 2.5" drives.
This is the first time in this phase of the SSD market's development that a
multibillion dollar company (Samsung's 2004 revenue was $55.2 billion ) has
entered the market.
Also in May 2005 - this was the first time
that the term "solid state disk" generated enough volume to show up on
the top referring searches to this site.
In
June 2005 -
M-Systems announced
availability of the industry's highest capacity 2.5" SATA SSD with 128
gigabytes of storage. SATA had been identified in STORAGEsearch.com's Q404
market research survey as the #1 most popular interface for future applications.
But at this stage in the market's development (Q205) only 10% of SSD vendors
(3) actually offered products with this interface.
In July
2005 - Texas Memory
Systems launched the industry's first SSDs with a 4Gb/s Fibre Channel
interface. The 3U rackmount system offered upto 128-gigabytes capacity and
500,000 random I/Os per second performance.
In August 2005 -
SimpleTech acquired
Memtech. The
acquisition of one SSD company by another has (so far) been a rare occurrence
but could become more common in future.
In September 2005 -
SimpleTech launched the
world's first dual interface SSD. At launch time the Zeus Dual Interface SSD,
with both a USB and
SATA interface,
offered capacities up to 192GB in a 3.5-inch form factor, and sustained
read/write rates of 60 MBytes per second.
In November 2005 -
STORAGEsearch published a new updated market penetration model for the SSD
market called -

2007 and reach $4.5 billion by 2010.
Also in March 2006 - the
number of market active SSD
manufacturers listed on STORAGEsearch.com
had reached 36.
In
April 2006 -
Solid Access
Technologies became the first SSD manufacturer to display end user pricing
online for the full range of its SSD products. Previously the volatile nature
of memory pricing and fear of price led competition had meant that most
SSD oems declined to publish any pricing data. The SSD pricing exclusion zone
included their own websites, press releases related to product launches, and
even our own SSD
Buyers Guide.
In May 2006 -
Samsung launched the
world's first high volume Windows XP notebook using SSDs.
In June
2006 - SiliconSystems

RAM technology. Samsung
said PRAM is expected to replace high density NOR
flash within the next
decade
Also in September 2006 - the growth of market interest
in SSDs was revealed by STORAGEsearch.com's
web statistics. Pageviews on our main
SSD page increased 50%
in September compared to the year before period, even though readership had
only grown by 10%. The pageview growth happened despite the fact that the SSD
page had slipped down to #3 (out of hundreds of storage categories.) This
indicates a concentrated shift by readers towards the hottest subjects that
matter most to their future plans. At the same time a greater proportion of the
most popular storage
articles were about SSDs.
Also in September 2006 -
Broadbus was acquired
by Motorola.
In October
2006 -
SimpleTech acquired UK
SSD maker Gnutek.
In

October 2007
Addonics Technologies
launched what it called a "low cost large capacity SSD" platform. It's
a PCI card that can be installed with 4 Compact Flash cards with inbuilt
RAID support. The risk
with this approach is that most CF cards aren't designed for intensive write
operations and don't have wear levelling controllers. That means if a user
installs such a product in a server application - as a lower cost alternative to
a true SSD - the storage media may fail in under a year.

| SSD Myths and
Legends - "write endurance" |
| Does
the fatal gene of "write endurance" built into
flash
solid state
disks prevent their deployment in intensive server acceleration
applications - such as RAID
systems? |
It
was certainly true as little as a few years ago.
What's the risk with
today's devices?
This article looks at the current generation of
products and calculates how much (or how little) you should be worried. |
 | |
| RAM based SSDs have been
used alongside RAID for years - but
flash SSDs are
physically smaller and have bigger capacity (upto 412G in 2.5", 832G in
3.5") and are lower cost than RAM-SSDs and could actually be configured
in standard RAID boxes. F-SSDs aren't as fast as RAM based products but a single
flash SSD can deliver 20,000 IOPs - which when scaled up in an array - starts to
look interesting.

Flash
Memory vs. Hard Disk Drives - Which Will Win? - article by Semico Research
There's
a confusing picture in many consumer products like phones, cameras and music
players in which one day it seems that the storage function is done by flash
and next day another company announces they're doing the same thing with
miniature hard disks.
Is there any sense to this seemingly random
choice?
This article uses pricing trends, technology trends and
unique market analysis insights to show that users and oems may be able to
reliably predict which storage devices will be most cost effective depending

| Z's Laws - Predicting
Future Flash SSD Performance |
A few months ago a
reader asked me a very good question.
"Is there an industry
roadmap for future flash
SSD performance?"
That prompted other questions like...
- How fast are flash SSDs going to be in 2009?, 2010? or 2012?
- What are the technology factors which relate to flash SSD throughput and
IOPS?
- How close will flash SSDs get to
RAM SSD performance?
There wasn't a simple answer I could give at the time. Clues lay
scattered all across this web site
and in my many one on one discussions with readers about the market... |
 |
But I agreed there should be
a single place on the web where these answers could be found.
Forget
Moore's
Law. That gives you the wrong answer, and this article explains why. ...read the article | | |

Timeline Correction
I
originally stated that - in January 2006 -
NextCom became
the first notebook maker to qualify flash SSDs*.
I later added the
note "for use in Windows XP, Linux and Solaris notebooks."
Thanks
to Robin Harris, editor StorageMojo.com
for this email note (April 19, 2006).
"The original
HP
Omnibook 300 offered a PCMCIA flash disk as a several hundred dollar
option ($400?) back in (I think) 1993.
"I know because I bought it and used one for years. The option
had 10MB of capacity and HP packaged in a compression utility that
automatically compressed everything on the flash card, so the effective
capacity was 20MB.
"The real benefit wasn't weight, as the 300 weighed in at 2.9lbs
with or without a hard disk. The win was battery life - which went to 10
hours with the SSD from about 3-4 hours with the HDD.
"With an instant-on feature that really worked, and a decent PDA
and terminal emulation, built in Word & Excel (to which I added
Powerpoint) I had a very solid, unfussy machine that I only had to charge
every few days. Lived with it daily for 5 years until I had to give it up
because it would no longer do what I needed."

More about one the early
references at the beginning of this article
I mentioned a
company at the start of this article called "Square D.
In
1978 they launched their 2nd generation programmable controller called the
SY/MAX-20. This was a real-time industrial computer which was EMI / RFI
hardened to operate reliably in factory automation applications alongside
welding equipment, cranes etc - and running through its entire program and
updating all I/O deterministically every 20 milliseconds. It used an
AMD
bit
slice architecture - organized as a 12 bit register and ALU - to run the
company's interpreted ladder logic language an order of magnitude faster than
the 8 bit microprocessors which were at that time available.
If you
read the Pulitzer Prize winning
Soul of a New
Machine (published 1981) which describes what was happening in Data
General's minicomputer design team - you get the general idea of what companies
were doing at this time.
When I joined the SY/MAX-20 design team in
1979 - the bit slice product had already been in volume production for a while.
The company was worried about the customer removable solid state
storage modules which held the customer programs. The 1st generation modules
had used electrically alterable memory chips - but the permanence and wear-out
were being revised drastically downwards compared to the original
extrapolated life which chipmakers had forecast.
So as many other
companies would do later - Square D - redesigned these modules to use battery
backed CMOS RAMs. Because these computers directly operated big dangerous
machines - in high electrical interference enviroments - it was critical to
design protection circuits around the removable solid state memory which would
guarantee that no data corruption occured regardless of how many transient
spikes might hit the logic system.
Another factor was that the
removable modules had to be capable of being dropped onto a concrete floor -
when out of the system - and also be capable of being inserted and removed
while the host system was under power - and run under extremes of temperature.
In
my time at Square D I designed some intelligent analog I/O modules - and then
moved onto other companies to focus on high accuracy process instrumentation and
pushing some boundaries in analog design.
Later in the mid to late
80s I was technical manager at a company whose business was to design the
world's fastest real-time I/O platforms for defense and research applications.
There we used solid state storage to run disk operating systems in
multi-processor VMEbus racks. We had to rewrite part of the OS, and we wrote all
our own drivers too, but that was common in those days.
The solid state
storage gave faster performance and better reliability than was available from
disk systems. We also built our own
RAID controller and
designed data recorders which could do wire-speed throughput of analog data to
hard disks and real-time radar to big memory arrays for our deep pocketed
government customers. They could analyze the data too - with internal array
processors or embedded SPARC workstations. It was great fun and a good
education for my later career here at StorageSearch.com. | |
