Charting the Rise of the Solid State Disk Market
|by Zsolt Kerekes,

published the world's first comprehensive history of the SSD market here on
StorageSearch.com. It has been used as the primary resource for many other "so
called" SSD history articles in other web sites and publications - although
the attribution is often notable by its absence.
This article lists key
technical, product and market milestones from 1976 to
2014. After decades in "virtual stealth mode", and many
false starts and setbacks, the SSD market is now coming out as an exciting
technology which will change the way all computers are designed.
|Coming of Age for SSDs|
manufacturers in the industrial controls market, like Square D and
Allen-Bradley were using rewritable user removable non volatile solid state
storage modules as early as the 1970s, it wasn't till much later that the
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
General Instruments. They had electrically controlled block erase (like later
flash memory). The block erase took 100 milli-seconds using a 42V pulse. Read
access time was 2 microseconds which was only 4x slower than other types of MOS
memory in those days. Unfortunately field use showed that the extrapolated
data life of 10 years wouldn't be achieved in practise. (The erase / write
cycle limit - or endurance as we now call it - was later downgraded by the
manufacturer to 1,000 cycles per cell - for 10 years retention - compared to a
much higher figure in the preliminary datasheets.) As a result many industrial
companies like the company I worked for in 1980 stopped using EAROM and
switched to battery backed CMOS RAM instead.
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.
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.
- 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.
In 1982 -
SemiDisk Systems (based in Beaverton Oregon) became the first company to ship
SSD accelerators for the Intel microprocessor based PC market.
first disk emulator cards were S-100 form factor RAM SSDs with 512 kilobytes
capacity ($1,995 price at launch). Internally they used 64Kb DRAM, worked via
a proprietary interface - and were designed to work with
S-100 computers (which had Z80 8
bit CPUs inside with a 64 kilobytes addressible bus). Soon after, SemiDisk
built similar cards for TRS-80 Model II computers, and IBM PC's, and Epson QX-10
computers, and increased the capacity to 2 megabytes when 256Kb DRAM became
Curtis introduced the
ROMDISK SSD for the
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.
Adtron developed its
first memory card drive for the proprietary memory cards manufactured by Epson
and Mitsubishi. These 1st generation memory card drives found applications with
companies such as GRiD, HP, and Trimble Navigation.
NEC marketed 5.25"
SCSI SSDs using internal battery backed
RAM. (Editor's note - I
benchmarked this SSD on a Sun SPARCengine blade for a real-time embedded defense
app using Oracle. But it wasn't fast enough for what my customer had in mind.)
Equipment Corp marketed the
family of Solid State Disk accelerators for use with its
Solid Data Systems was
founded. The company soon after patented technology for Direct AddressingTM -
which maximized SSD performance by translating SCSI addresses directly into
DRAM eliminating intermediate delays.
Amperif which had been selling a RAM SSD product called Arctic Fox.
In 1994 - The
SPARC Product Directory
listed 2 SSD products aimed at the Sun server market.
- T8000 - was an 80MB, 10MBps SSD on a single slot
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.
1995 - EDN magazine called
- "1994's most innovative product for embedded systems."
- 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
1996 - ATTO
Technology marketed the
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.
1997 - in the SSD market
white paper by Peripheral Concepts listed the main SSD vendors as:-
SEEK Systems, and
Solid Data Systems.
designed a RAM SSD
with hard drive backup. Sales Director - David Trossell told me - "It was
a little ahead of its time and the company dropped it after poor sales."
ComputerSysteme marketed a
of SSD modules which converted flash memory cards into
parallel SCSI flash SSDs.
1998 - STORAGEsearch.com published a daily updated
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
November 1999 - the number of market active
SSD manufacturers listed on
STORAGEsearch.com had reached 11.
- after 8 years featuring editorial about SSDs in our various publications,
Curtis became our first
SSD advertiser. (By
2011 100% of our publishing company's revenue came from SSD ads - as we stopped
accepting ads for any other types of storage products.)
In February 2000 -
unveiled the E-Disk ATE35 - the world's
PATA SSD with 200µS
average access time, 11MB/s burst R/W transfer rates, and 9MB/s sustained
R/W. Capacity options ranged upto 19GB.
- SST (Silicon
Storage Technology) entered the embedded mass data storage market with the
introduction of a flash memory-based ATA-Disk Chip (ADC) product family
packaged in a 32-pin DIP package and are available in a range of capacities upto
64 MByte. SST's ADC used a standard ATA/IDE protocol and could be used as a
replacement for conventional IDE hard disk drives.
- VMIC embedded
Diskonchip SSD into
Linux single board computers.
November 2000 -
Solid Data Systems
published an article - Solid
State File-Caching for Performance and Scalability
- which discussed the declining performance (versus capacity) in new
generations of hard drives - and showed how SSDs could boost the performance of
legacy servers and RAID systems by x4.
In May 2001 -
introduced a product called - FlashSSD - as an option in its OpenRAID
enterprise storage SAN products. This non-volatile solid-state disk was for
the typical 1% to 5% of an application's "hot files" that account for
50% or more of all disk requests. FlashSSD delivered a sustained and
constant 12,000 IOPS and 40MB/s data throughput. The company said - this
data rate is consistent for all types of I/O including all reads and writes, all
sequential and random transactions and for all large and small block transfers.
It could speed up disk based applications by 2x to 5x.
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 July 2001 -
Cenatek entered the SSD
market with the launch of its Rocket Drive - a PCI bus RAM SSD which was
designed as a performance accelerator "delivering performance of up to one
million transactions per second." The product's designer Jason Caulkins - went
on later to become the CTO of Dataram's SSD business.

(still at #1) got 42% more pageviews than the year ago period.
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 -
shipped the world's first Ultra320 SCSI flash solid state disk.

drives in traditional HDD form factors could economically challenge the R/W
throughput and random IOPs of the fastest enterprise
SSDs from EasyCo (array
of COTS SSDs) and Texas
Memory Systems (proprietary flash array) showed that flash SSDs could
replace some market niches previously held by
RAM SSDs - at much
lower cost and without worrying about wear-out.

the days when computers were made
first SSDs for use in Intel PCs|
|In 1982 - SemiDisk Systems (based in
Beaverton Oregon) became the first company to ship SSD accelerators for the
Intel microprocessor based PC market. |
SemiDisk's first disk emulator
cards were S-100 form factor RAM SSDs with 512 kilobytes capacity ($1,995
price at launch). Internally they used 64Kb DRAM, worked via a proprietary
interface - and were designed to work with
S-100 computers (which had Z80 8
bit CPUs inside with a 64 kilobytes addressible bus).
| Soon after, SemiDisk built
similar cards for TRS-80 Model II computers, and IBM PC's, and Epson QX-10
computers, and increased the capacity to 2 megabytes when 256Kb DRAM became
SemiDisk's founder - Jim Bell - told me (in 2014)
"the R/W throughput of these SSDs was limited by the Z-80 block transfer
function speed. (INIR, OTIR) So it was about 500 kilobytes/second speed. But
that was considered VERY fast in the early 1980's... Speed was always the main
benefit (and reason for buying)... It was mostly consumers and businesses who
Jim also said "One notable feature of these
cards is that they 'carpeted' the card with memory sockets that were literally
as close together as it was possible to push them! They used 'dipguard' type
decoupling capacitors, too."
Jim said he designed the prototype
of the SemiDisk in "about October 1980" - when he was working for
Intel in Aloha Oregon. He went on to say - "I built a device on a
wirewrap, prototype card, using 2118 5-volt 16kbit DRAMs. It had 32 sockets,
and I installed the chips 8-high. (Looked like a brick!; heavy, too,
because the chips were ceramic, specifically 'cerdip' devices.)"

History of Solid State Memory Storage (pdf)|
|This is a guide written by
accurately sums up one of the problems which faced SSD accelerator makers from
the late 1980s to mid 1990s period until
FC SANs got established.
Here's an extract...
"Over time many other vendors have
entered, and left the business of providing solid state storage systems. Solid
state developed a reputation of being really great, if you could afford it.
This was due to an inherent flaw in the basic design theory. In short, the flaw
arises from the fact that while the storage mechanism of a solid state device is
fast, the interfaces required to connect to a host system were not fast enough
to take advantage of the performance potential.
"During this timeframe (and continuing to the present time) most
solid state systems employ slow SCSI connections. During the 1980s, 1990s and
into the 2000s, SCSI
was a slow interface and could sustain data transfer rates of only 40 to 80 MB
per second. At these speeds, host computers could not really realize the
benefits necessary to capitalize on the very high initial investment solid
state storage is expensive!"
|when did it become clear
that SSDs would be a huge market?|
|Editor:- SSDs have been listed
in the buyers guides I've published since 1992. And in 1998 - I published the
world's 1st continuously updated directory of SSD oems (the url of which is now
our main SSD news page).|
talking to people in the SSD market and in processor chip companies (as part
of my SPARC market
acceleration work) in the late 1990s and early 2000s I guessed that SSDs had
the potential to become an economic mainstream solution (instead of an
expensive niche) to counter the flattening of the peak performance growth
curve in enterprise CPUs.
But how big would that SSD market be?
When I started talking to enterprise SSD companies about my market
2003 (at that time "enterprise
SSD" was synonymous with "RAM SSD") they were initially
skeptical. Each SSD company was only seeing a small part of the market. But my
SSD pages were acting as a focus point for all vendors and most users in the
industry. It was easy for me to get an overview picture which no one else was in
a position to see.
I talked to many SSD company founders at that time -
explaining my ideas, learning more about what their technologies could do. And
they told me about customer success stories which their customers didn't want
to publicize - because it would give their customers' competitors too many
insights into how they had solved strategic business problems using SSDs.
a consensus view started to emerge from these many 1 on 1s - some SSD
companies (including some in their early years of stealth mode) adapted
their business plans around the concept of a greatly expanded SSD market
A few years later - in
2005 - I
published a new version of my SSD market penetration model which looked at
all the possible market segments for SSDs instead of just the enterprise.
That model was precipitated by the steep dive in flash memory pricing which
meant that flash SSDs would soon be 100x cheaper than just a few years
Marketers in flash SSD companies liked the new model even
better. And were happy to tell me privately how useful it was. They even
started to quote from it - although by the time the text had made it into their
sales collaterals and web sites the original attribution was mostly lost.
Where are we now?

|Editor:- March 27, 2014 - I was a few weeks
late in discovering this talking heads SSD video... But I don't think 2 weeks
matters too much when the subject is the
history of flash memory

Roohparvar, COO - Skyera - who's been
in the non volatile memory business for 30 years and has over 480 patents (in a
conversation with David Davis
a really non technical way (which even a
VC or lawyer can
understand) Frankie Roohparvar covers the ground from the earliest nvm (cavemen
making marks), lists the iconic use cases for flash based products like ipods
and cameras - which kept this market alive and innovating - and brings things
right up to date with the business thinking inside Skyera's
petabyte scale SSDs.
|If your education didn't include semiconductor
physics - and you're still struggling with imagining how
MLC differs from SLC and
eMLC, and how
controllers and all those electrons (locked in leaky cells) inter-relate
to each other - Frankie's verbal explanation will make it all fit into place.
On the business case for Skyera's approach - Frankie Roohparvar
reaffirmed something which I think the company has always been clear about - "When
90% of the system cost is flash you really need to understand the
internal workings of flash (to drive the cost down to a new lowest level)."

"I know because I bought it and used one for years. The option

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
