Samsung's Next-Gen PM981 NVMe SSDs Surface

Samsung is the most well-regarded company when it comes to consumer SSDs. even if their SSD solutions do usually carry a premium versus the competition, that price delta is usually well justified: Samsung's SSDs are frequently the most reliable, fastest option in the market. Samsung's 960 PRO and 960 EVO SSDs have done a good job of clarifying the company's market positioning, and now, the successors for those Samsung SSDs have already surfaced.

The next-gen Samsung NVMe drives carry the PM981 code-name - where "PM" stands for TLC NAND (in this case, based on 64-layer 3-bit per cell V-NAND chips), "9" stands for Samsung's highest performing solutions, and "81" stands for the part number - two tiers ahead of Samsung's 960 series. It's expected that there will be a 970 part, since Samsung seems to be steering away from the "EVO" and "PRO" monikers to differentiate products according to performance - a straight numeral is expected to be the norm going forward. For now, the parts that have surfaced carry 512 GB and 1 TB of memory. These will make use of Samsung's Polaris V2 controller (with a metal heatsink over it to aid in cooling), and deliver 3,000 MB/s and 3,200 MB/s sequential read speeds (for the 512 GB and 1 TB versions respectively) and 1,800 MB/s and 2,400 MB/s sequential write, respectively. The models surfaced from a Vietnamese retailer, which has them going for $233 and $439 - which doesn't mean this will be the final consumer retail price, but seems reasonable for the technology and performance tier of these NVMe SSD solutions.

Toshiba Sells its Memory Business to Bain Capital for $18 Billion

Toshiba today announced that it has signed an agreement with a consortium led by Bain Capital to sell its memory business for JPY 2 trillion (approximately USD $18 billion). The consortium includes Korean memory giant SK Hynix, which contributed JPY 395 billion (nearly 20 percent) of the consortium's investment toward acquisition of Toshiba Memory Corp. Apple and Dell are the other members of the consortium.

Toshiba Corporation (erstwhile parent of Toshiba Memory Corp.) continues to hold a 40.2 percent stake, which along with another Japanese company, Hoya Corporation, holding a 9.9 percent stake, ensure that Japanese firms hold 50.1 percent of the business, keeping Japanese regulators happy. The Bain Capital-led consortium will hold a 49.9 percent stake, ensuring that Toshiba Memory Corp. stays afloat, and away from rival Western Digital, which has dragged Toshiba to a multitude of international courts and arbitrators. Apart from SK Hynix, the Bain Capital-led consortium includes Apple and Dell, who feared they would lose DRAM and NAND flash price bargaining power if Toshiba Memory fell in the hands of Western Digital, which owns SanDisk.

SanDisk Initiates New Arbitration Proceedings Against Toshiba In the ICC

Western Digital Corp. (NASDAQ: WDC) today announced that several of its SanDisk subsidiaries have filed an additional Request for Arbitration with the ICC International Court of Arbitration related to three NAND flash-memory joint ventures ("JVs") operated with Toshiba Corporation ("Toshiba").

On Aug. 3, 2017, Toshiba announced that it would unilaterally invest in manufacturing equipment for the Fab 6 clean room at the JV operations in Yokkaichi, Japan. The arbitration demand seeks, among other things, a permanent injunction preventing Toshiba from making unilateral investments in manufacturing equipment for Fab 6 without first giving SanDisk the opportunity to make a comparable investment in expansions and conversions of JV capacity for BiCS 3D NAND flash memory.

Western Digital commented: It is unfortunate that SanDisk is forced to initiate binding arbitration to remedy Toshiba's retaliatory breach of the JV agreement entered into by both SanDisk and Toshiba.

Team Group Launches L5 LITE-3D Series SSD

Targeting consumer's growing demand for computer storage capacity and higher performance, the world's leading memory brand, Team Group today announces the launch of the L5 LITE-3D SSD with all new 3D NAND technology. The latest generation of 3D NAND flash memory has overcome the technical barrier of 2D NAND. Featuring great durability and low energy consumption, it has become the mainstream memory of choice for the latest generation, enhancing overall capacity of solid state drives along with performance and reliability. It not only provides better performance and endurance, but also breaks through the technical and capacity limitations of planar chips.

The L5 LITE-3D solid state drive is 4 times faster than traditional hard drives. Its excellent performance and read/write speed not only allow fast boot/shutdown time, but also speeds up the response time of all application, so consumers can enjoy the high speed performance immediately after the upgrade. It is lightweight and has an industry-standard 2.5-inch form factor and is only 7 mm in thickness, making it best suited for Ultrabooks on the market. Whether it is for a laptop or desktop, the upgrade can be done quickly. It uses a SATA III 6Gbps interface and capacities are available in 120 GB, 240 GB, 480 GB, etc. The read speed performance is above 470 MB/s which offers the best performance-to-price ratio in the market right now.

Phison Also Looking to Introduce High performance E12 and S12 NAND Controllers

Phison isn't just a budget controller brand, as you well know, so in addition to their interesting, 2-channel NVMe NAND controller in the Phison E8, which should see products hitting retail in the following months, the company is also catering to the high performance crowds with the impressive E12 and S12 controllers. The E12 is definitely the star of Phison's new controller line-up - just look at those ratings of 3200 MB/s sequential read, 3000 MB/s sequential write, and 600K random read and random write IOPS. Naturally, those rated speeds should be taken with a measure of salt, as NAND type, its implementation and firmware tweaks all matter tremendously in extracting the best possible performance from high speed storage.

Contrary to the E8 budget Phison controller, the E12 will feature a full NVMe PCIe x4 interface, which allows for those speed ratings. The S12, on the other hand, is a more common SATA III controller, which means that its speeds of 550 MB/s sequential read and 530 MB/s sequential write are already hitting the interface's limits. Other than the interface and the rated speeds and IOPS, though, the specs are the same on these controllers: support for 3D NAND on MLC/TLC/QLC arrangements, 8-channel, LDPC, SmartECC, and End-to-End DPP support.

ADATA Implements SD A1 and V10/V30 Standards on Premier and Premier Pro Cards

ADATA Technology, a leading manufacturer of highperformance DRAM modules, NAND Flash products, and mobile accessories today confirmed that its Premier microSDXC/microSDHC UHS-I Class 10 cards now support the new SD Association A1 standard. Part of SD 5.1 specifications, A1 has been designed for running apps off external storage, going beyond traditional SD card uses such as accessing photos and video. At the same time, ADATA has also implemented V10 and V30 video recording capabilities on all of its Premier Pro microSD and SD cards, denoting at least 10MB/s and 30MB/s of video recording bandwidth, respectively.

An evolution long promoted by the SD Association, the A1 specification is part of SD 5.1 requirements. It shows that a microSD or SD card can support sufficiently high read speeds and IOPS counts to successfully run most apps without latency being an issue. In other words, A1 certified microSD and SD cards equal internal storage for app performance. They give users much greater freedom, as before apps were limited to internal storage even if large external storage was installed. With A1 and future specifications, users have the ability to install many more apps than would normally be the case, thanks to large add-in storage that is able to run said apps without compromise.

Across the range, ISSS314 drives reach 560 MB/s read and 520 MB/s write.

Where's My Storage? Viking Technology Begins Shipping 25 TB, 50 TB 3.5" MLC SSDs

If there's one thing enthusiasts usually complain regarding SSDs is that here doesn't seem to exist any viable alternatives to a good old high-capacity platter-based drives. Where are my 2 TB SSDs for 200$? How can I possibly save my entire music library in this puny 512 GB SSD that has already cost me my arms and legs?

Well, those answers might not be coming anytime soon (even though the advent of QLC NAND might change that.) In the meantime, we can put our eyes on Viking Technology, so as to see that a halo SSD product can achieve amazing storage capacity in a standard form factor. The company has just started selling their UHC (Ultra High Capacity) Silo Series, which leverage SK Hynix's MLC NAND (if the capacity doesn't put your $ klaxons running, the use of MLC should.) The SSDs leverage a 6 GB/s SAS interface, and deliver 500 MB/s read and 350 MB/s write speeds. The manufacturer says these can sustain up to 60,000 IOPS on random reads, and 15,000 IOPS on random writes. These may sound low in high-performance terms (and they sort of are), but remember these are products geared for the enterprise market. Pricing wasn't (maybe smartly) disclosed. I believe I'd laugh maniacally should I know how much they cost. However, if you must have a high-capacity SSD, you know where to look for.

Toshiba and WD Power Struggle Continues - WD Bid for Toshiba's Business 6 Times

You must remember the ongoing house of horrors that is Toshiba's financial situation. Granted, it isn't that bad - the company is still managing to push the envelope on its semiconductor production business. Still, I'm sure the company would have liked to not be on the verge of selling out 20% of its memory business production stake - which is one of the company's most profitable divisions to begin with.

Corsair Neutron NX500 SSD on Newegg; Available in 400 GB and 800 GB

Corsair has quietly added a new SSD to its portfolio which is currently available on Newegg. The new Neutron NX500 SSDs come in somewhat unusual 400 GB and 800 GB capacities, which likely means an overly increased over provisioning so as to ensure top endurance and performance. The Neutron NX500 SSDs come in the add-in NVMe card form factor, with a beefy heatsink to top it all up. That heatsink serves to cool not only the NAND chips, but also the Phison E7 controller that's lurking underneath.

Interestingly, and even though 3D TLC NAND is all the rage these days due to increased density on the same footprint, without bringing any serious, real-world problems related to endurance, as we've seen, the Neutron NX500 appears to pack MLC memory. Do you even remember that? That's part of the reason why performance is rated so high: there's 3,000 MB/s read, 2,400 MB/s writes, 300,000 IOPS in random read, and 270,000 IOPS on random write workloads. Though you will have to pay a pretty penny for this kind of performance: the 400 GB Corsair Neutron NX500 is currently retailing for $319.99, while the 800 GB version won't give you any benefits from the economy of scale: it retails for $699.99.

Toshiba Develops World's First 3D Flash Memory with TSV Technology

Toshiba Memory Corporation, the world leader in memory solutions, today announced development of the world's first BiCS FLASH three-dimensional (3D) flash memory utilizing Through Silicon Via (TSV) technology with 3-bit-per-cell (triple-level cell, TLC) technology. Shipments of prototypes for development purposes started in June, and product samples are scheduled for release in the second half of 2017. The prototype of this groundbreaking device will be showcased at the 2017 Flash Memory Summit in Santa Clara, California, United States, from August 7-10.

Devices fabricated with TSV technology have vertical electrodes and vias that pass through silicon dies to provide connections, an architecture that realizes high speed data input and output while reducing power consumption. Real-world performance has been proven previously, with the introduction of Toshiba's 2D NAND Flash memory.

Sk Hynix Begins Mass Production of 72-Layer 3D NAND

After announcing their intention to begin mass production of their latest 72-Layer 3D NAND Flash back in April, SK Hynix has now confirmed that it has entered mass production of the high density NAND modules. Apparently, SK Hynix has already achieved the much sought-after "golden yield" ratios, where the semiconductor yield is now at such a level that it is advantageous to finally enter mass production. Apparently, SK Hynix's leadership was fearful of not being able to achieve the golden yield in a timely manner after their announcement of the technology only three months ago; however, after its "management team and engineers repeatedly spent nights doing research, yield went up vertically and has become comparable to Samsung Electronics'" own yield - and as you know, Samsung is kind of the golden standard when it comes to NAND technology.

According to industry sources, SK Hynix is already mass-producing SSDs (Solid State Drives) with the company's own controllers and firmware which leverage this new 72-layer 256Gb NAND flash memory. This is a welcome change for the company which should allow it to increase revenue, since this is the first time controllers are developed in-house. The company is also said to be already producing eMMC (embedded Multimedia Card) for mobile devices based on this technology, with supply already arriving to its customers.

Samsung's New $13B V-NAND Factory Begins Production

Samsung is one of the top tech players in the world, with tendrils extending through almost all conceivable markets. That position, and the varied sources of income the company has at its disposal, gives it enough leeway to make investments that echo throughout the industry, Now, after a 15 trillion won investment (something like $13 billion), the company's latest V-NAND fab has started production in Pyeongtaek.

The fab will produce the firm's latest three-dimensional, 64-layer 256Gb V-NAND chips. Here's hoping the expected influx of higher quantities of NAND memory will allows us poor users to see a stop to the NAND pricing increase we've been seeing of late. Not everybody needs all the NAND available in smartphones.

Toshiba's 768 Gb 3D QLC NAND Flash to Match TLC's Program/Erase Cycles

Not all news coming out of Toshiba is bad or somewhat bad. The Japanese giant still is one of the biggest players in the NAND semiconductor business, no matter the recent woes. Even more recently, though, Toshiba announced they had developed quadruple level cell NAND memory, which should improve density and, therefore, reduce the price/GB ratio on future consumer products, such as SSDs. However, each increase in the number of cell levels bring concerns regarding not only performance, but especially durability, since a higher number of states per cell increases the voltage steps that are applied to it (SLC NAND dealt with two voltage states, MLC with four, TLC with eight voltage states, and QLC will handle 16 of these.) This tends to make errors more common, and the cell's longevity to be compromised due to the amount of variation in its states, which means more powerful error correction techniques must be employed.
According to Toshiba, its 3D QLC NAND targets around ~1000 program/erase cycles, which is close to TLC NAND flash. This is considerably higher than the amount of P/E cycles (100 - 150) expected for QLC by the industry, which means the company has achieved what many thought difficult. Toshiba has begun sampling of its 3D QLC NAND memory devices earlier this month. everything points to mass production on late 2018, early 2019, though, which means we still have a long way to go until we see this technology implemented. This won't be the one to save us from escalating NAND prices; we'll have to look to other, more market and supply-and-demand based factors instead.Source: Anandtech
