Toshiba - as a Top SSD Company

Editor:- March 10,2017 - Toshiba was ranked #5 in the Q4 2016 edition of the Top SSD Companies List which is researched and published by StorageSearch.com.

Toshiba's highest rank in this series was #3 in Q2 2008.


Who's who in SSD? - Toshiba

by Zsolt Kerekes, editor StorageSearch.com - January 2017

As a primary supplier of flash memory Toshiba has been involved in the industrial SSD market since that market began. But Toshiba didn't enter the SSD market with its own products until the 1st quarter of 2008 at which point Toshiba entered the Top SSD Companies List.

Toshiba entered the enterprise SSD market in 2009 with a range of SAS SSDs.

Toshiba's appearance in the 2.5" NVMe SSD market in 2016 was due to the rebranded product line from OCZ.


Toshiba - selected mentions from SSD Market History

In May 2008 - Toshiba acquired approximately $30 million of shares in Mtron.

In September 2008 - Toshiba sampled a 256GB 2.5" SATA MLC flash SSD with R/W speeds of 120 / 70 MB/s.

In December 2008 - Toshiba said it will sample a new family of MLC flash SSDs with 256GB capacity in 2.5" and 128GB capacity in 1.8" form factors in Q1 2009.

In January 2009 - Toshiba announced it will start volume production of dual port SAS SLC flash SSDs in Q2 2009. The 2.5" SSDs will have 100GB capacity, and 25,000 read IOPS, and 20,000 write IOPS. One of the enabling factors for the high write IOPS is the use of a non-volatile cache - which was predicted in StorageSearch.com's article - the Flash SSD Performance Roadmap. This brings the number of oems who have announced SAS SSDs to 6. See SSD Buyers Guide table for the full list.

In May 2009 - Toshiba announced it is offering 512GB SSDs as an option in notebooks for the Japanese market. The new, Toshiba-developed 512GB SSD employs a 2-bit-per-cell MLC flash memory - which gives 4x the capacity of SLC flash used in industrial and enterprise SSDs for the same silicon wafer footprint. One of the failures of the SSD market in 2008 was the low performance of SSDs integrated in notebooks. Toshiba's new notebook seems to address that market failure . The company says its new SSD controller boosts data throughput figures of 230MB/s reads and 180MB/s writes.

In September 2009 - A report in DIGITIMES said that Toshiba has ordered flash memory card controllers from ITE Tech to diversify its supplier base.

In January 2010 - Toshiba announced it is sampling 128GB mSATA MLC SSD modules (30mm x 50.95mm x 4.75mm ) aimed at the netbook PC market. Sequential R/W speeds are 180MB/s and 70MB/s respectively. Weight is 9g.

In April 2010 - Violin Memory announced it had received a significant investment from Toshiba.

In April 2011 - Toshiba announced it was sampling SmartNAND - 24nm flash memory chips (with upto 64GB capacity) with integrated ECC controllers to simplify the design of consumer products which need storage.

In January 2013 - Toshiba started sampling a new range of 2.5" SAS MLC SSDs - with self encrypting security features and on board sanitization.

In October 2013 - DensBits announced that it has licensed its advanced Memory Modem technology (a variety of adaptive R/W and DSP flash controller IP) to Toshiba for use in new designs of SSDs.

In November 2013 - OCZ announced that it would file for bankrupty and also said it had received an offer from Toshiba to acquire substantially all of its assets.

In January 2014 - Toshiba confirmed it had acquired the SSD product lines and assets of OCZ.

In January 2015 - Toshiba showed a prototype of the world's first PCIe single package SSD - with up to 256GB in a single BGA package.

In March 2015 - Toshiba sampled the world's first 48-layer 3D stacked 2 bit nand flash memory in 16GB chips.

In May 2015 - Toshiba demonstrated a hybrid storage drive which combined HDD and flash in a 3.5" form factor with an Ethernet interface.

In July 2016 - Toshiba said it was sampling 64 layer 3D TLC flash in a 32GB device.

who will make enough flash?
Editor:- March 14, 2017 - A fab capacity view of the flash industry's ability to meet demand for memory this year is presented in - Shootout At Yokkaichi - the NAND Industry at the Crossroads by William Tidwell, Semiconductor Analyst who regularly writes about such things on Seeking Alpha.

Among other things Bill discusses the state of production maturity within the major memory companies in their transitions to 3D and says:-

"Industry productivity is still low due to a condition that could be called planar overhang - that being the amount of planar capacity that must be converted as fast as possible to 3D, so the company can take advantage of the denser 3D process. Unfortunately, this conversion process from planar to 3D is basically like buying a house that has to be completely renovated and then finding out that load-bearing walls are involved - and the foundation has to be reinforced."

The article's central theme is the imminent auction of Toshiba's flash assets, the main competitors and possible bidders, winners and losers.

Along the way you get a good feel for the investment and production dynamics which will shape the next few years of this industry. ...read the article

Toshiba was fastest growing SSD vendor in 2016 says IDC
Editor:- March 8, 2017 - The flash business unit of Toshiba - which may be called something different depending when you read this - has announced that its SSD business was the 4th largest by market share and the fastest growing (year on year) in 2016 according to data in a report - Worldwide Solid State Storage Quarterly Update, CY 4Q16 ($40,000) - published recently by IDC.

is Toshiba salami slicing its memory heirloom?
Editor:- February 14, 2017 - Toshiba has today, again, topped mainstream media tech headlines due to the resignation of the company's chairman. In recent weeks - were I so inclined (to fan the flames of rumor) - I could have inserted some story or other about the sale of Toshiba's semiconductor business in this news page every day.

Instead I came to the conclusion that the real story was that there probably wouldn't be a single big story because the sale of the entire memory systems business to a single buyer (most likely another memory or SSD company) would inevitably introduce a delay due to antitrust hurdles. And Toshiba needs financial bandaids now.

Therefore, what we've been seeing is a fragmented approach - which on linkedin I described as "salami slicing" the memory business heirloom. Western Digital got some - but no one will get it all quickly due to caution about the impact of regulator antiacid.

OCZ ad

OCZ advertised its enterprise SSD products on StorageSearch.com for years before it was acquired by Toshiba in January 2014. Thereafter Toshiba continued the ad programs until the 3rd quarter of 2016 by which time Toshiba redeployed OCZ as a consumer SSD brand.

The banner ad above shows the OCZ Z-Drive 6000 - a 2.5" NVMe PCIe SSD with dual port failover - which began live as an OCZ product - sampling in September 2014 - and then 2 years later changed to the same number as a product in Toshiba's consolidated enterprise product line.
