If you’re an industry analyst like The SSD Guy you find that useful data can come from unexpected places. When Intel announced the sale of its NAND flash business to SK hynix this month the company also provided useful information about Optane SSD sales. You have to know a little bit about Intel’s organizational structure to understand. Let me explain.
The SSD part of Intel’s Optane business has been Continue reading “How Many Optane SSDs has Intel Sold?”
At its October Insight Conference Micron Technology finally revealed its 3D XPoint SSD, dubbed the X100.
While the company didn’t disclose too much about the device, it did brag about its speed, claiming that the X100 is the world’s fastest SSD, running three times faster than the fastest NAND flash SSDs and almost three times the speed of other XPoint SSDs. The product is said to Continue reading “Micron’s New XPoint SSD Finally Arrives”
Those of you who enjoy listening to podcasts may want to hear Ray Lucchesi (Silverton Consulting) and Keith Townsend (The CTO Advisor) interview The SSD Guy for their series “Greybeards on Storage.”
This interview is the series’ 86th episode covering the world of storage. These guys do a fantastic job of probing this industry with great enthusiasm and insight.
This episode is a 40-minute compendium of the sights and goings-on at the August 2019 Flash Memory Summit along with observations on the industry in general. It’s not strictly structured, and not strictly serious, but just three industry insiders having a lot of fun sharing their observations.
Some of the broad range of subjects that Continue reading “Podcast: Flash Memory Summit 2019”
The Storage Developer Conference in September gave a rare glimpse into two very different directions that SSD architectures are pursuing. While some of the conference’s presentations touted SSDs with increasing processing power (Eideticom, NGD, Samsung, and ScaleFlux) other presentations advocated moving processing power out of the SSD and into the host server (Alibaba, CNEX, and Western Digital).
Why would either of these make sense?
A standard SSD has a very high internal bandwidth that encounters a bottleneck as data is forced through a narrower interface. It’s easy to see that an SSD with 20+ NAND chips, each with an 8-bit interface, could access all 160 bits simultaneously. Since there’s already a processor inside the SSD, why not open it to external programming so that it can perform certain tasks within the SSD itself and harness all of that bandwidth?
Example tasks would include Continue reading “SSDs Need Controllers with More, NO! Less Power”
Once again The SSD Guy will be playing a part in the annual Storage Visions conference which has been moved this year to the Santa Clara Hyatt Hotel adjacent to the Santa Clara Convention Center. It’s now a 2-day conference (October 22-23) and has an agenda packed with interesting subjects, speakers, and panelists.
Storage Visions’ mission is to bring together the vendors, end users, researchers and visionaries that will meet growing demand for digital storage for the “coming data tsunami.”
I will moderate a panel on an exciting new technology that is currently known by a few different names, including “In-Situ Processing,” “Computational Storage,” and “Intelligent SSDs” (iSSD). It’s a kind of SSD that uses internal processing to reduce the amount of data traffic between the server and storage. This helps get past an issue that plagues many applications which spend more time and energy moving data back and forth than they do actually processing that data.
The panel, at 8:15 Monday morning, October 22, is Continue reading “Storage Visions Conference Coming Oct 22”
Those of you who enjoy listening to podcasts may want to hear Ray Lucchesi (Silverton Consulting) and Howard Marks (Deep Storage) interview The SSD Guy for their series “Greybeards on Storage.”
This interview is their 70th episode covering the world of storage. These guys do a fantastic job of probing this industry with great enthusiasm and insight.
This episode is a 42-minute compendium of the sights and goings-on at last August’s Flash Memory Summit along with a number of side trips into the world of SSDs and memory chips. It’s not strictly structured, and not strictly serious, but just three industry insiders having a lot of fun sharing their observations.
Some of the broad range of subjects that we Continue reading “Podcast: Flash Memory Summit”
I am proud to share the release of a new Objective Analysis report detailing the nonvolatile dual inline memory module (NVDIMM) market. Titled: “Profiting from the NVDIMM Market,” this report explains the What, How, Why, & When of NVDIMMs, and forecasts the market through 2021.
Readers are aware that I have been watching this market for some time, and never really know whether I should post about NVDIMMs in The SSD Guy or in The Memory Guy, since the boundary between memory and storage is bridged by these products. My solution: publish posts about this report in both blogs!
According to the Objective Analysis NVDIMM market model the NVDIMM market can be expected to reach nearly 12 million units by 2021, representing a 105% average annual growth rate. The forecast methodology used for this model has provided some of the semiconductor business’ most consistently-accurate forecasts. The report, which includes this forecast, was the result of thorough research into the technology and the circumstances that led to the introduction of NVDIMMs, NVDIMM vendor and user interviews, and briefings from those standards bodies that are diligently working to provide timely support for this new technology.
This in-depth 80-page analysis explores the Continue reading “NVDIMM Report Now Available”
Those who have been reading posts on The SSD Guy blog for some time have often heard me explain that SSD prices will not fall below HDD prices anytime soon. Last week Western Digital shared a roadmap that shows that we can expect for there to be a sizeable price gap between the two technologies at least through 2028.
Let me stop for a moment to point out that Western Digital Corp, or WDC, no longer has any reason to take sides in the HDD vs. SSD battle now that the company has acquired SanDisk, a leading SSD maker. Even before that, WDC’s HGST business has been the market leader in SAS SSDs for a number of years. WDC doesn’t take sides in arguments about SSDs vs. HDDs. Instead the company stands ready to sell whichever one the customer finally decides to use.
This post’s graphic comes from a chart that WDC used on October 11 when introducing its new MAMR head technology, which the company expects to propel HDD capacities up, and HDD price per terabyte down, for a number of years. To create this chart WDC’s HDD team joined forces with the SanDisk flash team to project both HDD and NAND price per terabyte for the next 11 years. The most important conclusion is that Continue reading “WDC: No SSD/HDD Crossover”
A few years ago The SSD Guy posted an analogy that Intel’s Jim Pappas uses to illustrate the latency differences between DRAM, an SSD, and an HDD. If we look at DRAM latency to be a single heartbeat, then what happens when we scale that timing up to represent SSDs and HDDs? How many heartbeats would it take to access either one, and what could you do in that time?
I still think it’s a pretty interesting way to make all these latency differences easier to understand.
Just recently I learned of a Rich Report video of a 2015 presentation in which Micron’s Ryan Baxter uses a different and equally interesting analogy based on tomatoes.
Tomatoes aren’t the first thing that comes to my mind when I think about SSDs, but this video may change my way of thinking!
The tomato slide, 9:30 into the presentation, is Continue reading “Comparing SSDs to Tomatoes”
Start-up NGD Systems (formerly NxGenData) has just announced the availability of an SSD with in situ processing – that is, the SSD can actually process data rather than simply store it. The new “Catalina 2” SSD is said to have the ability to run advanced applications directly on the drive.
NGD tells us that the SSD, which comes in both U.2 and AIC (PCIe add-in card) formats, is currently available for purchase.
If your memory is long enough you may recall that The SSD Guy wrote a post four years ago about something like this. At the 2013 Flash Memory Summit Micron Technology delivered a keynote detailing a research project in which they reprogrammed SSDs so that each SSD in a system could perform basic database management functions.
Although Micron demonstrated significant advantages of using of this approach, nobody, not even Micron, has followed through with a product until now.
NGD briefed me and explained that the data explosion expected with the Internet of Things will not Continue reading “NGD’s New “In-Situ Processing” SSD”
