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”
Only a week after announcing its Optane Enterprise SSDs Intel has launched m.2-format Optane SSDs for end users. It appears that we are at the onset of an Optane surge.
These SSDs communicate over the PCIe bus bringing more of the 3D XPoint’s performance to the user than would a SATA interface.
Pricing is $44 for a 16GB module and $77 for 32GB. That’s $2.75 and $2.40 (respectively) per gigabyte, or about half the price of DRAM. Intel says that these products will ship on April 24.
What’s most interesting about Intel’s Optane pitch is that the company appears to be telling the world that SSDs are no longer important with its use of the slogan: “Get the speed, keep the capacity.” This message is designed to directly address the quandary that faces PC buyers when considering an SSD: Do they want an SSD’s speed so much that they are willing to accept either Continue reading “Intel Pits Optane SSDs Against NAND SSDs”
With the tagline: “Bringing intelligence to storage” start-up NGD Systems, formerly known as NexGen Data, has announced a 24 terabyte SSD that the company claims to be the highest-capacity PCIe/NVMe device available.
The read-optimized Catalina SSD employs a lot of proprietary NGD technology: Variable rate LDPC error correction, unique DSP (digital signal processing) algorithms, and an “Elastic” flash transition layer (FTL), all embodied in an NGD-proprietary controller. This proprietary technology allows Catalina to offer enterprise performance and reliability while using TLC flash and less DRAM than other designs.
NGD claims that the product is already shipping and is being qualified by major OEMs.
Based on some of the company’s presentations at past years’ Flash Memory Summits the controller has been carefully balanced to optimize cost, throughput, and heat. This last is a bigger problem than most folks would imagine. At the 2013 Hot Chips conference a former Violin Memory engineering manager told the audience Continue reading “NGD’s 24TB SSD Is Just The First Step”
This week Intel announced the Optane SSD DC P4800X Series, new enterprise SSDs based on the company’s 3D XPoint memory technology which Intel says is the first new memory technology to be introduced since 1989. The technology was introduced to fill a price/performance gap that might impede Intel’s sales of high-performance CPUs.
Intel was all aglow with the promise of performance, claiming that the newly-released SSDs offer: “Consistently amazing response time under load.”
Since the early 1990s Intel has realized that it needs for the platform’s performance to keep pace with the ongoing performance increases of its new processors. A slow platform will limit the performance of any processor, and if customers don’t see any benefit from purchasing a more expensive processor, then Intel will be unable to keep its processor prices high.
Recently NAND flash SSDs have helped Intel to improve the platform’s speed, as did the earlier migration of Continue reading “Intel Announces Optane SSDs for the Enterprise”
Yesterday IBM unveiled a sweeping update of its existing flash storage products. These updates cover a range of products, including IBM Storwize All Flash arrays: V7000F, V7000 Gen2+, and V5030F, the FlashSystem V9000, the IBM SAN Volume Controller (SVC), and IBM’s Spectrum Virtualize Software.
The company referred to this effort as a part of a: “Drumbeat of flash storage announcements.” IBM has a stated goal of providing its clients with: “The right flash for the right performance at the right price.”
IBM’s representatives explained that the updates were made possible by the fact that the prices of flash components have been dropping at a rapid pace while reliability is on the rise. The SSD Guy couldn’t agree more.
Here’s what IBM announced:
Starting from the low end and moving up, the V5030F entry-level/midrange array is an Continue reading “IBM Refreshes Broad Swath of Flash Offerings”
Why are HDD prices tracking SSD prices? Why don’t they cross over? These are questions that The SSD Guy is often asked, especially by people who anticipate a crossover in the near future.
In essence it’s because both the HDD industry and the semiconductor industry have set goals for themselves to achieve 30% average annual price reductions. If they are both on the same trajectory, and if there’s an order of magnitude difference between HDD and SSD prices today, then there will be an order of magnitude difference in the future as well.
The 30% average annual decline in SSD prices has a convenient name: Moore’s Law. Although there’s no physical, economic, or other restriction behind Moore’s Law (so it’s not really a law at all) it serves as a guide for the industry. Chip makers set their sights at doubling the number of transistors on a chip every couple of years, and this equates to average annual price decreases of 30%.
The HDD business also Continue reading “Why SSD and HDD Prices Move in Parallel”
On Friday Toshiba revealed its restructuring plans aimed at returning the company to profitability and growth through management accountability.
Of special interest to The SSD Guy was the fact that the company will refocus its semiconductor and HDD businesses, currently called the “Semiconductor & Storage Products Company” partly by giving it a new name: “Storage & Electron Devices Company”. This division will focus on the semiconductor group’s good prospects and profitability while maintaining a focus on the fact that SSDs and HDDs share a business. In the not-too-distant past Toshiba has run these two businesses separately.
The group plans to be “A pillar of income with Memories as a core business”. To achieve this, Toshiba has stated that it will enhance its NAND cost competitiveness by accelerating development of BiCS (Toshiba’s 3D NAND technology) and by expanding the SSD business. There are three parts to this Continue reading “Toshiba Reveals Restructuring Plans”
The SSD Guy was recently asked whether HDDs would continue, at least through 2019, to remain preferable to SSDs as cost-effective high-capacity storage. The answer was “Yes”.
Longtime readers will note that I steadfastly maintain that HDD and SSD gigabyte prices are unlikely to cross for a very long time. Historically, a gigabyte of NAND flash has cost between ten to twenty times as much as a gigabyte of HDD. Let’s look at where Objective Analysis expects things to go by 2019.
Our current projections call for NAND price per gigabyte to reach 4.4 cents in 2019. I would expect for HDD to still be 1/10th to 1/20th of that price. Most likely 1/10th, since we expect for NAND flash to be in a significant oversupply at that time and will be selling at cost.
If HDD prices continue to hover around $50, then a 2019 HDD price of 0.44 to 0.22 cents per gigabyte (1/10th to 1/20th of the price of NAND flash) would imply an average HDD capacity of 11-23TB.
A couple of weeks ago, on December 2, 2015, Western Digital’s HGST introduced its Continue reading “Is an HDD/SSD Price Crossover Coming Soon?”
It’s really something to see a company recover from a big challenge, and signs of that happened this week with OCZ’s introduction of a new NVMe-based PCIe SSD they call the Z-Drive 6000 series.
This replacement for the company’s Z-Drive 4000 series is a complete redesign with an obsession for performance. OCZ tells me that they moved from a 2-hop design to a 1-hop by using the PMC Princeton PCIe SSD controller, and have passed the University of New Hampshire Interoperability Labs’ compliance tests to NVMe 1.1B compliance.
But how does it perform? Well the 1-hop design helps reduce latency (which is just starting to overshadow IOPS in users’ minds) and the latency of this SSD is significantly lower than competing NVMe SSDs: between 25-30μs, figures that OCZ tells me are very consistent, a big plus for enterprise applications. As for IOPS, the device can perform under a 70/30 Read/Write load at 330K.
The 6000 series is provided in both standard MLC and eMLC for those who want the security of eMLC and are willing to sacrifice a little performance to sleep better at night.
This product is a good fit for the market needs, and shows how devoted OCZ and its parent Toshiba are to providing high performance in the SSD marketplace.
