Tosh preps enterprise SSD push

On back of Fujitsu disk biz buy


Toshiba completed its acquisition of Fujitsu's disk drive business yesterday, and is set to move into enterprise disk drives, and server and enterprise storage solid state disk drives.

Toshiba Corporation now has a Digital Media Network company, which has a storage device division looking after business and product planning, and sales and marketing. A separate operations division will be responsible for production planning and procurement. Toshiba Storage Device Corporation will look after production and manufacturing engineering, quality assurance, design and development, and customer support.

Toshiba Storage Device Yamagata Corp will do HDD prototype development, Toshiba Information Equipment (Philippines) Inc will make 1.8-inch and 2.5-inch disk drives, and Toshiba Storage Devices (Thailand) will also make 2.5-inch drives. Toshiba Storage Device (Philippines) Inc will make the enterprise drives.

The two Toshiba Storage Device businesses are the ex-Fujitsu plants. With the Thailand plant, Toshiba will be able, as it says, to "reinforce its already strong market position as a leading vendor of small form factor HDDs." It says it will expand its enterprise HDD business and technology. There is a transition underway in the enterprise HDD business, from Fibre Channel drives to solid state drives (SSDs) and SAS drives, and from 3.5-inch to 2.5-inch drives. We can expect Toshiba to develop 2.5-inch 6Gbit/s SAS drives alongside the existing 3.5-inch drives acquired from Fujitsu.

It will also "develop SSD products for servers and enterprise storage systems by integrating its NAND flash memory technology with Fujitsu’s enterprise HDD technology." This must refer to the HDD controller circuitry and functionality, but it seems clear that Toshiba will require enterprise SSD controller technology for this as well. SandForce has recently emerged as a supplier of controllers for SSDs. LSI might also be a potential supplier here, as it was selected by Seagate to help with that company's enterprise flash drive controller technology.

Seagate is going to see competition from Toshiba in both the enterprise HDD and SSD markets. Toshiba is talking of becoming a "total storage solutions" supplier and we might see specific HDD and SSD products for particular markets as well as shipments into what we might call the industry standard disk drive markets.

We might also speculate about the longevity of Toshiba's 1.8-inch HDD product line, as that form-factor would seem susceptible to continued encroachment from SSDs. If Tosh bites this particular bullet, then manufacturing space currently assigned to 1.8-inch product could be redirected to 2.5-inch product and improve Toshiba's manufacturing volume there, lowering per-drive costs.

Interestingly Toshiba has areal densities in its 1.8-inch product of more than 500Gbit/sq in, well past the 350Gbit/sq in or so common in 2.5-inch drives at the moment. If Toshiba can transfer that technology to 2.5-inch drives then it could steal a march on both WD and Seagate and offer 2-platter, 1TB, 2.5-inch HDD product before the two industry leaders.

Talking of industry leadership, there are whispers that WD's unit shipments could surpass Seagate's by the end of the year. One swallow doesn't make a summer, but it will be a notable event that ends Seagate's long run as the industry's undisputed volume shipment leader. For Toshiba, such giddy heights are a long way off, but there are smaller fish to go after, such as Hitachi GST. ®

  • Will this be one of the world's first RISC-V laptops?
    A sneak peek at a notebook that could be revealed this year

    Pic As Apple and Qualcomm push for more Arm adoption in the notebook space, we have come across a photo of what could become one of the world's first laptops to use the open-source RISC-V instruction set architecture.

    In an interview with The Register, Calista Redmond, CEO of RISC-V International, signaled we will see a RISC-V laptop revealed sometime this year as the ISA's governing body works to garner more financial and development support from large companies.

    It turns out Philipp Tomsich, chair of RISC-V International's software committee, dangled a photo of what could likely be the laptop in question earlier this month in front of RISC-V Week attendees in Paris.

  • Did ID.me hoodwink Americans with IRS facial-recognition tech, senators ask
    Biz tells us: Won't someone please think of the ... fraud we've stopped

    Democrat senators want the FTC to investigate "evidence of deceptive statements" made by ID.me regarding the facial-recognition technology it controversially built for Uncle Sam.

    ID.me made headlines this year when the IRS said US taxpayers would have to enroll in the startup's facial-recognition system to access their tax records in the future. After a public backlash, the IRS reconsidered its plans, and said taxpayers could choose non-biometric methods to verify their identity with the agency online.

    Just before the IRS controversy, ID.me said it uses one-to-one face comparisons. "Our one-to-one face match is comparable to taking a selfie to unlock a smartphone. ID.me does not use one-to-many facial recognition, which is more complex and problematic. Further, privacy is core to our mission and we do not sell the personal information of our users," it said in January.

  • Meet Wizard Spider, the multimillion-dollar gang behind Conti, Ryuk malware
    Russia-linked crime-as-a-service crew is rich, professional – and investing in R&D

    Analysis Wizard Spider, the Russia-linked crew behind high-profile malware Conti, Ryuk and Trickbot, has grown over the past five years into a multimillion-dollar organization that has built a corporate-like operating model, a year-long study has found.

    In a technical report this week, the folks at Prodaft, which has been tracking the cybercrime gang since 2021, outlined its own findings on Wizard Spider, supplemented by info that leaked about the Conti operation in February after the crooks publicly sided with Russia during the illegal invasion of Ukraine.

    What Prodaft found was a gang sitting on assets worth hundreds of millions of dollars funneled from multiple sophisticated malware variants. Wizard Spider, we're told, runs as a business with a complex network of subgroups and teams that target specific types of software, and has associations with other well-known miscreants, including those behind REvil and Qbot (also known as Qakbot or Pinkslipbot).
