    AMD Changes SSD Strategy: High-End M.2/NVMe SSDs Incoming, Low-Cost R3 Drives Are Here

    Over the past week or so, we noticed other news outlets reporting on the AMD R3 series of SSDs, as if there had been a recent press release circulating under the radar. This wasn't the case: despite the fact that the R3 SSDs have been out for a number of weeks, one news outlet decided to run a story and the rest followed the echo without investigating further. We put it direct to AMD about how the R3 SSD release was under the hood, and how the R7 drives had also been removed from listings. We had an interesting response, which we would like to summarize and discuss here.

    R7 Out, R3 In

    AMD’s Radeon R7 SSDs were developed by OCZ and featured 64 Gb NAND flash chips from Toshiba made using the company’s second-generation 19 nm (A19) fabrication process. In many ways, the drives resembled OCZ’s ARC 100 and Vector 150 drives, but since Toshiba is phasing out its NAND flash made using 19 nm manufacturing technology, the Radeon R7 SSDs are also discontinued and right now online stores are selling the remaining inventory.

    For the newer Radeon R3 family of SSDs, AMD chose a different partner. The drives are manufactured by a contract maker and then distributed by Galt, the company that distributes AMD’s Radeon-branded memory modules. Working closely with companies like SK Hynix, or OCZ, allows AMD to tailor certain aspects of SSD performance and offer a different (well, to a certain degree) differentiation point that is not available from anyone else. Moreover, since SK Hynix is a relatively small player on the SSD market, it is interested in increasing its share and may be flexible about pricing. AMD admits that the new R3 drives are indeed slower than the older R7 ones released earlier due to the movement from MLC to TLC, but it notes that they are considerably cheaper too, which was one of the primary reasons why the company decided to sell them. Furthermore, since Galt now handles logistics for AMD's DRAM and SSD products, it can do everything a little more efficiently in terms of costs.

    The newer AMD Radeon R3 solid-state drives come in 2.5"/7 mm form-factor and are based on the quad-channel Silicon Motion SM2256KX controller as well as TLC NAND memory made by SK Hynix. The new SSDs are available in 120, 240, 480 and 960 GB configurations, which are rated for up to 520 MB/s maximum sequential read speed as well as up to 470 MB/s maximum sequential write speed. Like other TLC NAND-based drives, the Radeon R3 SSDs use a part of its flash memory in pseudo-SLC mode for caching and performance-acceleration purposes.

    However, the release of the Radeon R3 SSDs does not mean that AMD simply leaves the market of more advanced SSDs and focuses on low-cost models.

    New R7/R9 On The Horizon

    AMD intends to introduce new higher-end Radeon SSDs towards the end of the year, the company said this week. Quite naturally, AMD remains tight-lipped about exact plans, but it confirmed that the new family will include faster SATA drivers as well as M.2/NVMe drives for future platforms. Keeping in mind that AMD does not seem to stick to one supplier of memory or drives, the new Radeon R7 SSDs (or will they be called Radeon R9?) may come from a new supplier. Nonetheless, if AMD intends to continue working with manufacturers with their own NAND (or, at least, a very tight relationship with actual makers of flash), then the list of its potential partners will be relatively short.

    When AMD introduced Radeon-branded memory modules several years ago, the company said that those products were optimized for its platforms, which was important as AMD needed faster DDR3 DRAM to improve the higher supported memory and performance of its APUs in graphics applications. As an added bonus, Radeon-branded memory modules was a way to give something back to its loyal customers as well as modders. With the Radeon R7 SSDs, the company pursued the same strategy but never attempted to expand the family of its storage devices. By now, Radeon-branded non-graphics hardware seems to have become a noteworthy part of AMD’s business, which is why it is gradually expanding the lineup of such products (e.g., the company introduced its DDR4 memory modules months ago, well ahead of any AMD APUs/CPUs with DDR4 support). Since TLC NAND is here to stay, it is pretty obvious that by the end of the year the company will offer SSDs for a variety of market segments: R3 for the entry-level and R7 (or R9?) for the higher-end.

    Some Thoughts: AMD in SSDs (and DRAM) Feels a Bit Odd, Right?

    The art of selling rebadged components, or using an ODM/OEM relationship and then adding a name on to it, might not seem like a true integration into these markets. While there are DRAM modules and SSDs with AMDs name on them, they are not actually investing much research money into driving the industry forward - these are turn-key solutions, similar to the way that local brands have smartphones that are identical apart from the sticker and the software. The reason for AMD reaching out with SSDs and DRAM (which likely offer little-to-no margin compared to the rest of the products) comes down to support, validation and system integrators.

    By offering an AMD brand SSD or DRAM module, it means that if a customer wants guaranteed compatibility and a single source for their parts, they can ring up an AMD distributor. This simplifies support for any component that needs to be replaced and means that inside and out everything comes up AMD (or as much as possible). It allows system integrators to offer their customers validated AMD hardware packages as well.

    The iPhone SE Review

    Last month Apple announced a new iPad and a new iPhone. While the iPhone was new, it was also familiar in many ways because it was direct successor to Apple's iPhone 5s which had been on the market for two and a half years. According to Apple, they sold thirty million 4-inch iPhones in 2015. Thirty million smartphone sales is a figure that many companies would be happy with for their flagship smartphone, but in Apple's case it's really interesting because that aging iPhone 5s was the only 4-inch iPhone they were selling. Being able to sell thirty million two-year-old smartphones is a pretty good indicator that there's a market for a smaller iPhone, and with the iPhone 5s approaching the end of its lifetime it was time to replace it. Read on for the full review of the iPhone SE to see what changes Apple has brought to the 4-inch form factor.

    Western Digital’s Acquisition of SanDisk Officially Closes

    Western Digital announced on Tuesday that the Chinese authorities have approved its acquisition of SanDisk. The regulatory approval from China's Ministry of Commerce (MOFCOM) in connection with the planned acquisition completes the regulatory review process required for this buyout. As a result, the transaction officially closed on Thursday. By taking over SanDisk, Western Digital will become one of the world’s largest suppliers of storage devices and solutions, which will be able to address virtually all kinds of storage needs.

    “This transformational combination creates a media-agnostic leader in storage technology with a robust portfolio of products and solutions that will address a wide range of applications in almost all of the world’s computing and mobile devices,” said Steve Milligan, chief executive officer of Western Digital. “We are excited to now begin focusing on the many opportunities before us, from leading innovation to bringing the best of what we can offer as a combined company to our customers. In addition, we will begin the work to fully realize the value of this combination through executing on our synergies, generating significant cash flow, as well as rapidly deleveraging our balance sheet, and creating significant long-term value for our shareholders.”

    The combined company will control over 40% of the HDD market, around 10% of the SSD market and a substantial chunk of NAND flash supply (together with Toshiba, SanDisk operates the world’s largest NAND flash production complex). The new entity will also be very powerful financially: last fiscal year Western Digital achieved revenue of $14.6 billion and net income of $1.5 billion (down from $15.1 billion and net income of $1.6 billion a year before), whereas SanDisk’s annual revenue for the 2015 fiscal year was $5.56 billion, a decrease of 16% from 2014. But while the combination of Western Digital and SanDisk has a huge potential, it will not be easy for the two companies to become one, especially keeping in mind that Western Digital and SanDisk have not fully absorbed HGST, Fusion-io and a number of other companies they acquired in the recent years. 

    Portfolio Overlap

    In the coming quarters, Western Digital and SanDisk will have to optimize their product lineups and either integrate or eliminate redundancy projects, two rather tough challenges.

    The explosive growth of the solid-state storage market helped to create rather innovative developers of NAND-based storage solutions for enterprises and hyperscale data centers, whereas established players faced a new reality and had to become parts of bigger entities. To strengthen its portfolio of products for the lucrative data center market, SanDisk has acquired Pliant Technology, FlashSoft, Schooner Information Technology, SMART Storage Systems and Fusion-io in the recent years. Because of its multi-billion takeovers, SanDisk greatly expanded its portfolio of products as well as intellectual property. What is important to note is that even now some of SanDisk’s products overlap and address essentially similar market segments.

    Western Digital was not sitting idle too. In addition to HGST (which currently absorbs the majority of Western Digital’s enterprise NAND-related assets), the company bought Virident, STEC, VeloBit, Amplidata and Skyera. Western Digital is not new in the SSD world: the takeover of SanDisk adds NAND flash manufacturing capacities, something that Western Digital needed to become a vertically integrated provider of HDDs, SSDs and all-flash storage arrays. This means that in addition to Western Digital gaining a lineup of consumer SSDs, it does mean there are a number of overlapping product lines and a lot of staff in similar roles.

    A major challenge for Western Digital and SanDisk will be optimization of their workforce in the coming quarters. It can be expected that the two companies may have to lay off a number of people and there are two problems with this. Firstly, takeovers by large corporations are usually followed by brain drain on all levels: both companies have already lost many people from Fusion-io, Skyera, Amplidata and others. The integration of SanDisk into Western Digital could accelerate departures of other people. Secondly, workforce optimizations amid resignations might disrupt product development and execution of roadmaps.

    Keeping in mind that Western Digital is now in the midst of HGST integration, the situation becomes even more complicated. Until recently, WD and HGST had separate R&D divisions and product roadmaps. Unification of different research and development operations can have short-term effects on R&D because usual teams and workflows are disrupted and then new ones are yet to be established. Adding SanDisk to the equation essentially makes things even more difficult. But that is not the only challenge.

    Product Lineups: The Competition Continues

    At present, Western Digital’s subsidiary HGST uses NAND flash memory from Intel (or IMFT/Micron) to make its enterprise-grade SSDs. Keeping in mind that the two companies have a supply and development agreement in place, it is highly likely that development of solid-state drives based on Intel’s 3D NAND is well underway. Moreover, since Intel and Micron seem to pin a lot of hopes on their second-gen 3D NAND (which production starts this summer), it is possible that HGST will have to use this type of memory as well. A good news is that Skyera’s skyHawk FS all-flash storage array should support various types of NAND memory (including SanDisk’s) because Micron, Toshiba and SK Hynix all invested in the company later acquired by Western Digital and Skyera worked with all of them. Meanwhile, HGST’s FlashMax PCIe SSD accelerators (which it got from Virident) rely on Intel’s NAND, whereas S-series SSDs (which the company got from STEC) use Toshiba’s memory.

    Since we are talking about enterprise-grade storage, for which development and validation can take years, it is clear that HGST will continue to use third-party NAND for the foreseeable future, unless Western Digital terminates the agreement with Intel, drops already developed products and replaces them with those designed by SanDisk. Even in this case, it will have to sell Intel-based Ultrastar and FlashMax drives for some time so not to upset customers.

    Meanwhile, SanDisk naturally uses its own NAND flash as well as its own controllers to make its SSDs for enterprise markets. Such drives compete against products designed by HGST and not all customers of the two companies could easily switch suppliers of SSDs because their storage systems are tailored for particular drives. In short, HGST’s Ultrastar and FlashMax will continue to compete against SanDisk’s Lightning, Optimus and Fusion ioMemory drives/accelerators for quite a while. Moreover, it looks like Western Digital’s skyHawk FS will also compete against SanDisk’s InfiniFlash to a certain degree.

    While the integration of the two companies into one seems to be challenging, the addition of SanDisk’s consumer SSDs to Western Digital’s product lineup is a big deal. It is not a secret that PC form-factors that cannot house 2.5” HDDs are gaining popularity, whereas the total available market of HDDs is declining. It is also noteworthy that there is a rather tough competition between low-end SSDs and HDDs for inexpensive notebooks. By offering both SSDs (especially single-chip SSDs like iNAND) and HDDs, Western Digital will be able to address traditional laptops, emerging 2-in-1s, tablets, ultra-thin notebooks and many other new types of PCs. Moreover, with SSDs and HDDs in its portfolio, Western Digital will be able to offer just what PC makers need for low-cost machines (without having to reduce margins to minimal levels just to get a design win). While SSDs will naturally compete against HDDs, this will unlikely hurt Western Digital. On the other hand, entering SSD market and competing against Samsung is a tough challenge, especially with overlapping products, internal competition, redundant workforce and the necessity to align roadmaps of two companies as well as Toshiba.

    Impact on Rivals

    Two interesting things that we will have to observe in the coming years will be the impact of Western Digital’s acquisition of SanDisk on the market of storage in general as well as on their rivals, namely Intel, Micron, Samsung, Seagate and Toshiba.

    While Intel has a broad SSD portfolio, which includes client and server drives, enterprise storage has been Intel’s primary focus from the very start. Development of storage class memory (3D XPoint) as well as its long-term vision of data center architecture indicates that Intel wants a significant and lucrative chunk of the enterprise storage market. Since the company is a major supplier of server CPUs, it is plausible that it will be a main provider of emerging NVDIMM SSDs for the future Intel Xeon platforms. Western Digital (HGST) will remain Intel’s SAS SSD development partner for a while, but Intel does not plan to supply 3D XPoint memory to any other makers of drives at this time, meaning HGST will not be able to address the highest end of the enterprise SSD market with 3D XPoint. However, since both SanDisk and Western Digital have been developing various storage platforms tailored for particular needs (such as HGST’s Active Archive System and Fusion-io’s InfiniFlash), there will be huge parts of the market that the combined company will be able to address without directly competing against Intel. Moreover, SanDisk is developing storage-class memory with HP, which will help to compete against Intel’s 3D XPoint eventually.

    Micron was historically focused on the production of DRAM and NAND memory, but in the recent years it accelerated its push into actual products based on their chips. Right now, the company offers a portfolio of SSDs for virtually all market segments, including big data analytics, databases, hyperscale/private data centers as well as virtualized environments. Micron will continue to compete against SanDisk’s SSDs for respective segments and will be able to build hybrid storage solutions when/if needed together with Seagate. What Micron cannot do today is to offer all-flash storage arrays like Western Digital’s Skyera. Moreover, with Western Digital’s takeover of SanDisk, Micron will lose a customer for its NAND flash memory eventually, which is not necessarily a bad thing, given the company’s focus on products and not on commodity chips.

    Speaking of Seagate, we should note that the company is facing major challenges. The firm does have state-of-the-art storage technologies, it offers Nytro solid-state storage accelerators, SandForce SSD controllers and various solutions in its arsenal (in fact, the company even claims to  havethe  world’s fastest SSD in its portfolio). However, Seagate does not have its own NAND flash production (unlike two of its competitors, Toshiba and Western Digital), which is why its chances on the market of consumer SSDs are somewhat limited due to cost reasons and strong competition from Samsung  (the only big fabless SSD suppliers are Kingston and LiteOn). Being unable to supply storage products for emerging PC form-factors greatly limits Seagate’s growth potential in general because while HDDs are not going anywhere in the next decade, or even two, their usage in the client PCs is set to decline, and so far sales of high-capacity HDDs for hyper-scale data centers have not offset declines of client hard drives. Recently Seagate announced plans to reduce its own HDD production capacities to improve financial positions, but it remains to be seen how this could help it to guarantee either a steady supply of NAND flash or its own NAND flash production capacities. In any case, Seagate will continue to fiercely compete against Western Digital in the growing market of high-capacity hard drives for cloud data centers and that will impact the third remaining maker of HDDs, Toshiba.

    Right now, Toshiba is the only company in the world which sells both SSDs and HDDs, an exclusive advantage it is about to lose. The company does not have helium-filled hard drives in its arsenal to address the most lucrative part of the hyper-scale data center market with 8 TB and 10 TB models. Moreover, unlike its partner SanDisk, Toshiba did not acquire any solid-state storage startups to address the market of all-flash storage systems for data centers. The company still has very advanced SAS and PCIe SSDs in its lineup, hence, it can compete for the market of solid-state accelerators, even though its capabilities are somewhat limited here due to the lack of sophisticated enterprise-grade caching software. While Toshiba has its own NAND flash and HDD production capacities, it yet has to gain technologies (software, hardware, etc.) to better compete for lucrative parts of the storage market. At present, Toshiba is in the midst of a financial scandal and it is hard to expect it to focus on revamping its storage capabilities at this time. However, it remains to be seen what happens next.

    SSDs? HDDs? The Industry Needs Solutions!

    While client storage technologies are important, enterprise storage will remain the most lucrative segment of the market. The data center today is evolving very quickly and for many applications a dedicated level of multi-tiered storage of HDDs, SSDs or even a combination of them, is still not enough. Don’t get me wrong here: we still need purpose-built hard drives and solid-state drives, but in many new cases they are not installed in general purpose servers but are a part of storage solutions that are designed for particular purposes. Historically, such solutions came from companies like EMC, IBM, HP, Hitachi Data Systems, Netapp and so on. However, in the recent years the market of external storage solutions began to transform.

    Firstly, a variety of startup companies has started to sell all-flash storage solutions. These can offer a number of advantages since such firms usually build everything (except flash) in-house and use custom technologies and know what they are doing very well. All-flash arrays, such as SanDisk’s InfiniFlash (512 TB of NAND, 2 million IOPS, 3U form-factor) or Western Digital’s Skyera skyHawk FS (136 TB of NAND, 400K IOPS, 2.4 GB/s, 1U form-factor), provide numerous performance and cost advantages over traditional HDD-based data storage solutions, which is why such all-flash arrays are gaining popularity these days. Furthermore, since they are purpose-built, they deliver performance right out of the box and solve rather complex problems.

    Secondly, traditional makers of hard drives in the recent years entered the market of storage systems with Active Archive (HGST), ClusterStor/OneStor (Seagate) and some other HDD-based storage arrays. Such devices are based on high-capacity hard drives and are designed to store massive amounts of data. While sales of many mission-critical storage systems are declining because of all-flash arrays (we see it in the reports of HDD makers as well as industry reports like the one linked above), systems optimized for archive and nearline storage are gaining traction.

    To get expertise to develop storage arrays, both Seagate and Western Digital acquired multiple companies in the last few years. However, only Western Digital can now build all-flash storage arrays using its own NAND flash, own controllers and own SSDs. Meanwhile, Seagate will have to rely on SSDs co-developed with third-party providers. A good news is that the company has a long-term development agreement with Micron, but it remains to be seen whether Seagate will be able to offer anything comparable to all-flash arrays from SanDisk or Skyera.

    While storage solutions may not be the primary business for Western Digital today, in a world where IT is moving to either private or public clouds, expertise in hybrid-flash and all-flash storage arrays is hard to overestimate. Obviously, the company will need different types of products to address public and private cloud customers. Hypothetically, as one big company with various assets, Western Digital could be able to address everyone with the right products, provided that it manages to smartly integrate SanDisk, HGST and others without losing valuable assets and people en route.

    Final Words

    The acquisition of SanDisk by Western Digital not only transforms the latter into a vertically-integrated maker of storage devices and platforms, but reflects many industry trends. Client devices transit to flash storage, whereas IT computing is moving to the cloud. To offer the right solutions, Western Digital needed a new set of assets and the takeover brings them to the company.

    On paper, Western Digital is now the only company which can build (pretty much) any type of storage device, from a single-chip SSD for tablets to a storage array featuring SSDs and NAND flash. In many ways, Western Digital is now a competitor not only to companies like Seagate, Toshiba, Micron and Samsung, but to EMC, HPE, Intel, Hitachi Data Systems and others. Fighting many wars is a tough business and it remains to be seen how well will it work out for Western Digital.

    However, winning market share from EMC or HPE is not the main concern of the company right now. The biggest challenge for Western Digital today should be to integrate all of its parts into one company, eliminate redundancies, streamline product lineups, avoid internal competition and keep up the pace of innovation.

    G.Skill Unveils New Trident Z DDR4: Five New Colors

    G.Skill has introduced new additions to its Trident Z family of DDR4 memory modules, which are designed to simplify the lives of anyone who wants to color-coordinate their PC. The new Trident Z lineup includes memory sticks with five new color schemes which are designed to match the aesthetics of overclocking and gaming motherboards.

    Just 10 to 15 years ago, PC modding used to be reserved for hardcore enthusiasts, who were willing to spend time and money to build beautifully looking PCs using custom-made components. PC cases with built-in LEDs or even transparent windows were in the minority, with only fully custom liquid cooling systems as a deviation, and the vast majority of motherboards were either slowly implementing color schemes or remained green/brown. Memory modules with heat spreaders were considered stylish. Fast forward to 2016, we have plenty of mass-produced components with PC modding features and almost everyone with moderate knowledge of PC hardware can build a PC with matching color scheme as well as lighting. The new Trident Z memory modules further simplify building of computers with unique designs, something that gamers and enthusiasts want to do.

    The G.Skill Trident Z series comes with two vectors: the main body and the top bar. The main body is either black or silver, and the top bar can come in orange, yellow, white or black. The original Trident Z modules featuring a silver body and black brushed aluminum heat spreader with a red top-bar highlight will remain on the market. Meanwhile, new color schemes (such as those with orange and yellow bars) will come in handy for those building new PCs based on the latest ASUS ROG, GIGABYTE Super Overclock or MSI XPower/MPower motherboards.

    The new G.Skill Trident Z memory modules have 8 GB or 16 GB capacities and are based on Samsung’s 8 Gb DDR4 ICs. The Trident Z will be available in dual-channel and quad-channel kits with 16, 32, 64 and 128 GB capacities, targeting everything from gaming desktops to higher-end workstations. Initially, G.Skill will offer colorful Trident Z kits with DDR4-3200, DDR4-3300, DDR4-3333, DDR4-3400 and DDR4-3466 speed-bins, CL14, CL16 or CL16 latencies as well as the higher DDR4 standard voltage (which is normal for high speed DDR4). The Trident Z Color are aimed at a good price/performance ratio for the majority of PC enthusiasts. Offering too many DDR4-4000+ SKUs with different color schemes could make lives of retailers uneasy since such modules are not too popular because of their high price. Therefore, if you want to go DDR4-4000 and higher, you will have to stick to “classic” Trident Z color scheme: black and silver heat spreader with red top-bar highlight.

    I know Ian has taken a delivery of some of these modules for future testing, in the silver body and white bar design. As shown below, these are 16GB modules at DDR4-3200 and 14-14-14-34 sub-timings, installed in the GIGABYTE X170-Extreme ECC.

    G.Skill intends to make the new Trident Z modules available this month. Since such modules only feature new heat spreaders, but continue to use the company’s own design PCBs as well as Samsung’s mass-produced 8 Gb DDR4 chips, they should not cost significantly more than existing Trident Z solutions.
