DRAMeXchange says - supercycle of DRAM price hikes is over

Editor:- October 9, 2018 - DRAMeXchange today reported how it's interpreting memory pricing and supply trends.

Re DRAM - DRAMeXchange says:-
  • DRAM products have begun to see a weak price trend, showing only a 1~2% QoQ hike in contract prices for 3Q18 due to the continued oversupply, despite the coming of holiday sales season. DRAMeXchange expects the quotations of DRAM products to decline by 5% or more QoQ in 4Q18, terminating the super cycle of price growth for 9 consecutive quarters.
  • DRAM manufacturers all expect a high possibility of oversupply in 2019. Therefore, they have tried to postpone or slowdown the capital expenditure and capacity expansion.
  • For 2019, DRAMeXchange expects the annual bit output to increase by nearly 22%.
re nand flash - DRAMeXchange says:-
  • nand flash experienced a price drop of around 10% in 3Q18 and expects a steeper drop of 10~15% in the fourth quarter, considering the impacts of trade war. Contract prices of 3D TLC NAND Flash chips in the channel market may even drop by more than 15% in 4Q18.
  • The nand flash market is influenced by the sluggish demand for consumer electronics, while demand for the more profitable Enterprise SSD from servers and data centers remains stable. However, the competition among Enterprise SSD suppliers will become increasingly fierce; hence the prices of Enterprise SSD are very likely to continue decreasing in 2019.
  • On the supply side, nand flash suppliers have raised their output forecasts as they have expanded their production capacity and improved the yield rates of their 64/72-layer 3D NAND production.

DRAM market - update from IC Insights

Editor:- March 6, 2018 - Are the Major DRAM Suppliers Stunting DRAM Demand? asks the 2018 McClean Report by IC Insights.

"In 2017, DRAM bit volume growth was 20%, half the 40% rate of increase registered in 2016. For 2018, each of the 3 major DRAM producers (e.g., Samsung, SK Hynix, and Micron) have stated that they expect DRAM bit volume growth to once again be about 20%. However monthly year-over-year DRAM bit volume growth averaged only 13% over the 9-month period of May 2017 through January 2018." the article

AFA market revenue grew to $1.6B in 3Q17 - says Dell'Oro

Editor:- December 6, 2017 - "AFA market revenue grew 33% yoy in 3Q17, reaching $1.6 Billion" according to a new report - Storage Systems Quarterly - published by Dell'Oro Group.

"All Flash Array is a very important technology segment in external storage. In fact, as a percentage of external storage revenue, it has been growing dramatically—from 22% in 3Q16 to 28% in 3Q17. So every vendor is determined to expand their position in all-flash storage systems" said Jimmy Yu, VP at Dell'Oro Group.

Editor's comments:- Dell'Oro's press release lists the 5 biggest vendors and the company can provide more analytical data in their purchaseable reports.

PCIe SSDs (enterprise and notebook M.2) did well in Q3

Editor:- November 15, 2017 - TrendFocus today published SSD market shipment data for Q3 2017.

Only one segment, enterprise PCIe, saw unit growth where every other segment – client drive format factor, client modules, enterprise SATA and enterprise SAS, all declined from the prior quarter.

Trendfocus SSD report Q3 2017The enterprise SSDs market declined 7% Q-Q, which includes SATA, SAS and PCIe. The bright spot within this overall decline was the healthy 15.6% increase in PCIe units. As hyperscale companies continue to migrate away from SATA, PCIe should continue to grow in both units and exabytes. SATA, still the highest volume of all enterprise categories, managed to stay just above 4 million units shipped but did decline sharply in CQ3. However, exabytes shipped in the SATA SSD market grew due to the transition to higher capacity units. SAS SSDs now represent the lowest unit volume of the enterprise SSD segments, but still maintain a large lead in average capacity shipped at over 2.1 terabytes.

Client SSD shipments fell 4.5% sequentially but exabytes shipped was flat. Client modules now represent almost 2/3 of all client SSDs shipped. Even more impressive within this segment is that M.2 PCIe is now 50% of this segment – illustrating the continued migration for major Notebook OEMs to integrate with this interface.

3D NAND accounted for more than 50% of all bits shipped for the first time in CQ3, as all of the NAND suppliers are well into the transition.

new report sizes NVDIMM market at 12 million units in 2021

Editor:- October 19, 2017 - October 22, 2017 - Objective Analysis opined today that the market for NVDIMMs is poised to grow at a 105% average annual rate to nearly 12 million units by 2021.

This forecast is a part of the company's new 80-page report titled - Profiting from the NVDIMM Market (outline pdf), single user price $6,500 - which among other things predicts unit and revenue shipments through 2021.

hyperscale is nearly 1/4 of all enterprise storage revenue

Editor:- September 14, 2017 - A new report from IDC confirms the growing size of the enterprise storage systems market related to hyperscale datacenters. Sales by ODMs to the hyperscale segment grew 73.5% year over year to $2.5 billion in in the 2nd quarter 2017 to reach nearly a quarter of the entire $10.8 billion in all segments.

Editor's comments:- 5 years ago in my article - the big market impact of SSD dark matter - I wrote about the future importance of web scale and cloud companies to the development of the enterprise SSD market. These users have been leading the curve in mainstream storage and memory architecture adoption because they get immediate cost. benefits from efficiency oriented designs.

These changes in storage market segmentation have also encouraged new rackmount SSD vendors to nurture significant business ambitions with unbloated lean product catalogs while ignoring traditional (declining) legacy markets.

miscellaneous consequences of the 2017 memory shortages

Editor: - September 7, 2017 - This has been a year like no other in the 40 year SSD market experience. In a new blog on - miscellaneous consequences of the 2017 memory shortages - I look at the pain points and share with you my analysis of where I think the big fixes to the memoryfication market challenges will come from. The time lag for a market fix can be understood better if you appreciate that the speediest mitigation won't come from the wafer fabs. the article

among the awards at FMS

Editor:- August 11, 2017 - With so many things going on in the SSD and memoryfication markets the best of show award winners category at the annual Flash Memory Summit has - in past years - provided a useful way to filter interesting developments. And this year is no exception. Among the many awards - 2 things caught my attention:-
  • IO Determinism - won an award for Toshiba and Facebook. Although by no means a new virtue within benchmarking nevertheless the recent award has refreshed the idea with a new spin. read more about it
You might say that what the 2 different awards above share in common is the desire for predictability in environments which are beset by highly chaotic elements.

IC Insights reports record breaking memory ASPs

Editor:- July 20, 2017 - A recent research note about the memory market by IC Insights puts an interesting spotlight on memory shipments.

Among other things IC Insights says:- "DRAM, unit shipments are actually forecast to show a decline this year. Moreover, NAND shipments are forecast to increase only 2%."
memory price data from IC Insights
When it comes to price expectations IC Insights says this.

"Even though DRAM ASP growth is forecast to slow in the second half of the year, the annual DRAM ASP growth rate is still forecast to be 63%, which would be the largest annual rise for DRAM ASPs dating back to 1993 when IC Insights first started tracking this data. The previous record-high annual growth rate for DRAM ASP was 57% in 1997. For NAND flash, the 2017 ASP is forecast to increase 33%, also a record high gain. (In the year 2000, the predominantly NOR-based flash ASP jumped 52%).

For those who need much more information IC Insights publishes a 250 page report ($4,090) which includes various free monthly updates. more

Editor's comments:- One message to take away from this is that as memories have been transitioning to the next multiple of 3D layers the chip throughput from the industry's legacy wafer fabs has stayed the same or gone backwards due to the extra time taken to reliably make those extra layers to create higher bit density memories.

TrendFocus reports sequential decline in raw storage drive capacity sold in Q1 2017

Editor:- May 16, 2017 - TrendFocus today announced market highlights related to storage drives in Q1 2017.

The number of exabytes shipped in HDDs and SSDs fell sequentially by 5% but was 19% higher than the year ago period.

TrendFocus says several factors contributed to the decline:- including weak PC sales, cyclicality in data center spending, and tight NAND supply affecting SSD buying patterns.

Re delays in storage spending in data centers:- TrendFocus says...

"Some large hyperscale/data center companies purchased fewer HDDs and SSDs in the quarter, temporarily slowing exabyte growth in the segment responsible for driving the highest long-term rate of capacity demand."

Editor's comments:- whereas higher prices of flash SSDs due to fab production capacity constraints and lower than expected yields in new memories has undoubtedly been a significant factor in the market - another thing to keep your eye on is the potential for big users to get more use out of the same raw capacity by using newer software.

That's a factor which can surprise the market at any time as I discussed in my warning article about the impact of the SSD software event horizon.

Another long term trend which will depress storage drive sales will be the refocus on memoryfication architectures.

I'm not going to attribute this 5% decline in raw storage drive byte shipments to the adoption of new memory architectures. It's probably just a correction with many causes.

But looking ahead to the next several future years you should not be surprised to the impacts on the storage drive market which could be much higher.

low yield at sub 20nm is root of DDR4 shortage says DRAMeXchange

Editor:- April 14, 2017 - Quality problems in DRAMs which have been sampling this year at the new sub 20nm generation from major suppliers is at the heart of the issues discussed in a new - market view blog by DRAMeXchange - which concludes that the contract prrice of 4GB DDR4 DRAM modules will rise 12.5% entering 2Q17.

Avril Wu, research director of DRAMeXchange said - "PC-OEMs that have been negotiating their second-quarter memory contracts initially expected the market supply to expand because Samsung and Micron have begun to produce on the 18nm and the 17nm processes, respectively. However both Samsung and Micron have encountered setbacks related to sampling and yield, so the supply situation remains tight..." the article

2017 will be crossover revenue year for DDR4 says IC Insights

Editor:- April 13, 2017 - A new report about the DRAM market by IC Insights says:-
  • DDR4 prices in 2016 fell to nearly the same ASP as DDR3 DRAMsAs a result, IC Insights expects DDR4 to become the dominant DRAM generation in 2017 with 58% market share versus 39% for DDR3.
  • Following a year of extraordinary gains in pricing, a boost to DRAM supply in the second half of 2017 could lead to reduced ASPs and the inevitable start of a cyclical slowdown in the DRAM market. the article

New ingredients in the mix for storage market clairvoyants

Editor:- July 20, 2016 - What do you predict will happen in the storage market in the future? And how "real" are some of the newer technologies that you read about in web pages like this?

As a technology publisher for over 20 years I've been fortunate to have my own advance signals like talking to company founders, investors emails, web stats and inquiries about advertising for future product lines. And I use those to guide my priorities within the lanes that I write about.

Gerard Blokdijk CEO of The Art of Service (based in Brisbane Australia) has published a new market research report - Storage Technologies predictive analytics report ($97) which evaluates 36 storage-related hardware and software technologies in terms of their business impact, adoption rate and maturity level to help users decide where and when to invest.

"Data sources include trend data, employment data, employee skills data, and signals like advertising spent, advertisers, search-counts, instruction and courseware available activity, patents, and books published."

Editor's comments:- As a publisher who has helped to accelerate the adoption of new technologies by writing about them I have often said that new technologies become real when you see them advertised because editorial, and trade show activity in the storage market often precedes by 3 to 5 years the general availability of innovative new products which you can buy.

The Art of Service's inclusion of employment signals and product ads into the analysis mix sounds like a useful methodology difference compared to reports and trackers seen in this market before.

enterprise PCIe SSD shipments grew 16% Q-Q

Editor:- May 18, 2016 - TrendFocus today announced publication of its Q1 2016 nand/SSD quarterly market report.

TrendFocus says the enterprise SSD market saw growth in all segments - SATA, SAS, and PCIe.

Trendfocus  reports SSD market Q1 2016 shipments

For enterprise SATA SSDs, unit growth compared to the previous quarter was 5%, while SAS and PCIe saw higher growth at 6.7% and 16.3%, respectively.

Editor's comments:- In Q1 2016 SSD shipments reported by TrendFocus were 30 million units. Compare this to Q1 2014 for which period TrendFocus reported 15 million units. This shows SSD shipments over all markets have doubled in 2 years.

enterprise SSD petabytes doubled in China in 2015

Editor:- March 15, 2016 - Gregory Wong, President, Forward Insights says that Enterprise SSD petabytes doubled YoY in the China market in 2015. While at the same time - shipments of all types of SSDs grew 3x faster in the China market than the overall worldwide market.

Editor's comments:- Greg was coy about giving me exact numbers when I asked - which is why you got ratios instead in the story above - but you will be able to find raw numbers in his new report - Opportunities in China's SSD Market - which will be published next month. Whoops - I forgot to ask the price. Most of Forward Insights' past SSD reports have been in the region from aroung $5K to $10K.

top storage companies by revenue

editor:- February 5, 2016 - StorageNewsletter recently compiled a list of the Top 12 Storage Companies in 2015 (ranked by revenue).

This isn't the same as top SSD companies (by revenue or search volume) but there will be a degree of convergence between the 2 during the next 5 years.

Back in January 2001 I launched a series called the The 10 biggest storage companies - in which I tried to predict 2 years in advance who the top 10 would be (based on revenue).

That worked surprisingly well - but I EOLed the series when my primary focus became SSDs.

Interesting looking back that in 2001 Dell wasn't regarded by most people in the market as a serious storage company - and including them in my list stirred the enterprise pot.

IHS names 3 enterprise SSD billion dollar revenue companies

Editor:- November 20, 2015 - Earlier this year I promised you a $billion / year enterprise SSD companies list (which I haven't done yet).

If you can't wait (and like short lists) then IHS has done this already for enterprise SSD drives (which excludes rackmount flash systems).

IHS's list of enterprise SSD billionaires include 3 companies:- You can see the numbers in a new article here (on Electronics360).

Among other things it says "IHS forecasts that the SSD market to pass $13 billion in revenues this year and will surpass HDDs in revenue by 2019 with $20.8 billion versus $19.6 billion."

As you may recall I said something similar (the SSD market will be bigger in revenue than the HDD market ever was) in my 2012 article - How will the hard drive market fare... in a solid state storage world?

3D X-Point could shrink DRAM market by 1/3 in 5 years

Editor:- October 23 , 2015 - Coughlin Associates has recently published a new report on Emerging Non-Volatile Memory and Spin Logic (163 pages, $4,000).

The memories addressed in this report overview (pdf) include PRAM, RRAM, MRAM, STT MRAM as well as the recently announced 3D X-Point Technology.

3D X-Point Technology will have a big impact on DRAM growth (with DRAM sales down $6.7 billion to $15.6 billion due to XPoint by 2020) with XPoint revenues of $663 million to $1.5 billion by 2020.

MRAM and STT MRAM revenue is estimated at $1.4 billion to $3.2 billion by 2020. Manufacturing equipment revenue for MRAM and STT MRAM production is estimated to be between $159 million and $294 million by 2020.

DCIG publishes new edition of its AFA Buyers Guide

Editor:- September 30, 2015 - DCIG recently announced a new edition of its All-Flash Array Buyer's Guide (60 pages, free signup) which - from a desk based research stance - describes, comments on, and compares in depth the features of key products in this category from 18 selected vendors in the market (AMI, Dell, EMC, Fujitsu, HDS, HP, Huawei, IBM, iXsystems, Kaminario, NetApp, Nimbus Data, Oracle, Pure Storage, SolidFire, Tegile, Violin Memory and X-IO).

Editor's comments:- One of the roles for this document which DCIG suggest is as a "short list" for quickly and conveniently getting your hands on consistently-presented, in-depth datasheets for a market snapshot of products from a range of credible sources.

As to how the sample list of vendors is cast - DCIG clearly stated they do not merely rely on vendors paying them for inclusion in the list. Nevertheless one of the problems with the authority of any "buyers guide" is the degree of inclusivity and (by implication) the transparency of filtering criteria.

When you include hundreds of products in such a guide from all known vendors - then the sampling process is transparent (and those not in the guide - need to make better efforts to communicate with their market) but when you have a guide which samples only a small percentage of vendors then inevitably questions get asked about how those in the sample were chosen.

My guess on the representational value of the companies listed in the guide is that it's compatible with the kind of shortlist you'd get by sampling from 3 broad criteria.
  • companies added into the list based on public revenue criteria and corporate brand strength (to ensure inclusion of older, long established storage companies)
  • companies added into the list based on search strength, or social media derived ranking rather than revenue (to ensure sampling of some newer companies)
  • companies added into the list for arbitrary reasons (maybe they've got a particularly interesting feature which the authors want to discuss as a counterpoint to others, or maybe the authors have some special relationship with the company which means they know more about it)
It took me about 30 seconds after seeing DCIG's vendor list that the above (or some reverse analysis thought process like it) is probably as good an explanation as any for DCIG to have constructed its list.

I'm not saying that's how they did it. But if you had to construct a vendor list of reduced size (and DCIG does have to because - due to their format - it would be cumbersome, repetitious and wasteful of analyst time to scale the guide to hundreds of vendors) this is as good a way as any other - for the purpose of discussing representational features in the AFA market.

So in that respect (unlike others) I don't have any quarrel with the sample they've chosen.

It sure wouldn't be my list. But DCIG's authors are aiming to produce a different kind of guide and they see their added value as coming from their proprietary vendor scoring criteria. And that necessitates a different kind of list.

In a free competitive market - reports compete for your attention - just as much as products. And you don't have to like every feature to learn something useful from them.

DCIG's scoring criteria is where I part company with DCIG's thinking. And this is a gulf I can't bridge.

I just have to look away from these pages to prevent my crystal ball cracking for reasons I explained when discussing an earlier version of this guide back in March 2014.

I think the scoring concept intrinsically suggests a much more stable, restricted and naive model of the SSD enterprise than is currently the case. In some respects the scoring concepts are like a bridge too far and sometimes to the wrong places and sometimes entirely missing some critical destinations.

Nevertheless I'm sure DCIG's new guide will serve adequately for many people who see things the same way as the guide creators do and who like their way of doing things. So I'm sure there will be more editions of this guide in future.

It's not DCIG's fault that the enterprise SSD market resembles at times the navigational uncertainty of Lost in Space (tv series) when in the very first episode the rocket gets hit by a meteor storm.

In the SSD market we've been through a whole bunch of similar cosmic disturbances and our rocket was launched with no clear destinations in mind at the outset. The best we can hope for is plausible pragmatic reinterpretations at convenient refueking stops.

BTW - I'm not suggesting that anyone else could do a better scoring job by using different methodologies.

Instead what I'm saying is that such a style of analysis is inappropriate because of current defects in enterprise SSD market models and the general understanding of them.

While that situation persists - such simplistic "winner" style guides run the risk of advocating the essential flavor of beef to vegetarians.

SSD market slowing down?

Editor:- June 22, 2015 - In a new observation on the state of the SSD market - SSD Insights Q2/15: Slowing Down - Gregory Wong, President, Forward Insights said this...

"The weak PC market and tepid datacenter demand affected shipments of SATA SSDs in Q1/15. This was offset by strong shipments of SAS SSDs and SSDs into the channel which benefited from aggressive pricing, particularly in Asia."

growing user confidence will spur enterprise flash consolidation

flash backed DIMMs - new directory on

Editor:- October 21, 2014 - Although has been writing about flash backed DRAM DIMMs since the first products appeared in the market - I didn't think that subject was important enough before to rate a specific article or market timeline page.

That's unlike memory channel SSDs - which is now 1 of the top 10 SSD subjects viewed by readers after having had its own directory page since April 2013.

However, sometimes a market is defined as much by what it isn't as by what it is.

And so - to help clarify the differences between these 2 types of similar looking storage devices (one of which I think is much more significant than the other - but both of which are important for their respective customers) I have today created a directory page for hybrid DIMMs etc - which will act as the future pivoting point for further related articles.

Evaluator Group announces new report series for rackmount SSDs

Editor:- September 24, 2014 - Evaluator Group today announced it's expanding its comparison report coverage (from around $2,750 for IT end-users) related to rackmount SSD and hybrid array vendors.

The latest addition to EV's research area are product analyses for 15 vendors, including: Cisco, EMC, HDS, HP, IBM, Kaminario, NetApp, Nimble, Nimbus, Pure Storage, SanDisk, SolidFire, Tegile, Tintri and Violin.

"Over the next 3 years Evaluator Group expects Solid State Storage Systems to be the architecture adopted for primary storage," said Camberley Bates, Managing Partner & Analyst at Evaluator Group. "Performance to reduce latency and improve consistency, along with reliability and efficiency functionality will drive this change. It is important IT end users understand the trade-offs of design and technical implementation to best suit their needs."

Using the Solid State Evaluation Guide to understand the critical technology characteristics EV says IT end users can clearly identify their requirements and priorities. The Solid State Comparison Matrix allows for side-by-side comparison of product specifications and capabilities. Evaluator Group guides IT end users through the process with product reviews and expertise on managing and conducting a Proof of Concept. Evaluator Group Solid State Storage Systems coverage includes products specifically designed to exploit the characteristics of all solid state deployment.

What will you be getting? EV is offering a free evaluation copy of their report for the IBM FlashSystem to people who sign up for it.

Editor's comments:- with so many different architectural roles for enterprise SSDs and different user preferences - it's unrealistic to suppose that any simple side by side product comparisons will suit all permutations of user needs. But having said that - any reliable information which assists user education and comprehension into SSD arrays is a good thing.

Some flash array vendors - realizing the futility of expecting that users will understand what their products do and how they will interact with the bottlenecks and demands of unknowable user installations and prederences - have instead side-stepped these delay laden hard user selection quandries - exaggerated by the very real personal concerns of getting it wrong - by instead offering new risk delineated pricing models - as described in my article - Exiting the Astrological Age of Enterprise SSD Pricing.

In the modern era of SSDs - the customer has received their education about what an SSD is - and what it can do - from many sources. So when they talk to a vendor - the customer says - don't tell me about SSDs. Tell me instead how you fit into my idea of the SSDs I'm looking for.

The big market impact of SSD dark matter
In the early 1980s - Intel's 1M bit bubble memory created a lot excitement as a new non volatile solid state memory technology.

It was positioned as a solid state floppy disk.

But it wasn't scalable or cost effective.

Intel spun off the magnetic division in 1987 to Memtech (who later made military flash SSDs) but bubble memory dropped into oblivion.
