  • Western Digital Ships 12 TB WD Gold HDD: 8 Platters and Helium (AnandTech)

    Western Digital has begun to ship its WD Gold HDD with 12 TB capacity to partners and large retailers. The 3.5” drive relies on the same platform as the HGST Ultrastar He12 launched this year, and will initially be available to select customers of the company. The WD Gold 12 TB is designed for enterprise workloads and has all the performance and reliability enhancements that we come to expect, but the availability at retail should make them accessible to wider audiences.  

    From a hardware point of view, the WD Gold 12 TB is similar to the HGST Ultrastar He12 12 TB hard drive: both are based on the fourth-generation HelioSeal technology that uses eight perpendicular magnetic recording platters with a 1.5 TB capacity for each platter. The internal architecture of both HDDs was redesigned compared to predecessors to accommodate the eighth platter. Since the WD Gold and the Ultrastar He12 are aimed at nearline enterprise environments, they are equipped with various sensors and technologies to protect themselves against vibration and as a result, guarantee sustained performance. For example, the WD Gold and the Ultrastar He12 attach their spindles both to the top and the bottom of the drives. In addition the HDDs feature a special technology that increases the accuracy of head positioning in high-vibration environments to improve performance, integrity, and reliability. Finally, both product families support TLER (time-limited error recovery) rebuild assist mode to speed up RAID recovery time.

    Since the WD Gold 12 TB and the HGST Ultrastar He12 are similar internally and feature the same 7200 RPM spindle speed, they also have similar performance — the manufacturer puts them both at 255 MB/s sustained transfer rate and 4.16 ms average latency. The main difference between the WD Gold and the HGST Ultrastar He12 are the enterprise options for the latter: there are models with the SAS 12 Gb/s interface and there are models with SED support and Instant Secure Erase feature.

    Western Digital aims its WD Gold and HGST Ultrastar He-series drives at operators of cloud and exascale data centers that demand maximum capacity. The 12 TB HDDs can increase the total storage capacity for a single rack from 2440 TB to 2880 TB, replacing 10 TB drives with 12 TB drives, which can be a major benefit for companies that need to maximize their storage capacity per watt and per square meter. Where the HGST-branded drives are made available primarily through B2B channels, the WD Gold are sold both through B2B and B2C channels and thus can be purchased by wider audiences. For example, boutique PC makers, as well as DIY enthusiasts, may start using the WD Gold 12 TB for their high-end builds, something they could not do with the HGST drives. These HDDs may be considered as an overkill for desktops, but since WD’s desktop offerings top at 6 TB, the WD Gold (and the perhaps inevitable future WD Red Pro 12 TB) is the WD’s closest rival for Seagate’s BarraCuda Pro drives.

    The WD Gold HDD is currently available directly from Western Digital for $521.99 as well as from multiple retailers, including Newegg for $539.99. While over $500 for a hard drive is expensive, it is actually less than Western Digital charged for its WD Gold 8 TB about 1.5 years ago ($595) and considerably less than the initial price of the WD Gold 10 TB drive last April.

  • Lian Li Launches PC-T70 Test Bench (AnandTech)

    Lian Li has been one of the few large case manufacturers to consistently offer test benches over the years, and they have now launched their newest model, the PC-T70. First unveiled at CES 2017, this new test bench was developed with feedback from PC hardware reviewers and it has been designed with an eye towards easy access and simple hardware swapping. There is also an optional accessory kit that encloses the test bench with an acrylic cover, which simulates a closed-air environment and allows for testing conditions that more closely match a regular closed case. For those who would rather have the whole kit from the start, Lian Li will also be offering the PC-T70FX, which comes with the acrylic cover and side panels included.

    Starting off with the fundamentals, the PC-T70 is manufactured from both aluminium and steel and it is available in both black and white. It can handle motherboards ranging from Micro-ATX to E-ATX, and it has eight expansion slots that support cards up to 330mm in length, though longer cards should be fine as well if you don't install the acrylic cover. There is one small and six large pass-through ports that are used to cleanly route cables to the lower half. The bottom chamber can handle one ATX power supply up to 330mm in length, and it is also where you can install your choice of either five 2.5” and one 3.5” storage drives or one 2.5” and two 3.5” storage drives. There is also mounting space for some liquid cooling hardware, namely an up to 360mm radiator, a reservoir, and a pump. The front of the test bench features a small I/O area consisting of a 3.5mm audio input, a 3.5mm audio output, two USB 3.0 ports, and both power and reset buttons.

    If you have more advanced cooling needs, or if you're a reviewer that wants to be able to simulate a closed-air case environment, the T70-1 option kit is an accessory ​that is going to be of great interest:

    As mentioned above, the optional T70-1 upgrade kit encloses the test bench with an acrylic cover and side panels that serve as radiator mounts. The idea is that by enclosing the motherboard and other heat-generating components, reviewers will be able to simulate closed-air case environments that are more representative of the insides of regular PC cases. This should ensure more accurate testing of both thermals and acoustics. It should be mentioned that with the cover installed, CPU cooler height is reduced from an effectively unlimited height down to 180mm. Magnetic strips help secure the cover and keep it closed during transport.

    Also helping to secure the cover are the panels that enclose the side and back of the test bench. The aluminium side panels feature large cutouts with removable dust filters, and that is because each side panel can hold two 120-140mm fans or a single 240-280mm radiator. The rear panel has mounting holes for one additional 120mm or 140mm fan.

    The PC-T70FX model, which includes the T70-1 option kit, is available right now at Newegg.com for $180 USD. It is unclear if the solo PC-T70 will be available for sale in the future, though we suspect that it will because it has its own product page on Lian Li's website.

  • Crucial Announces DDR4-2666 DIMMs for Upcoming Server Platforms (AnandTech)

    Crucial this week introduced an expansion of its server-grade modules lineup with DDR4-2666 offerings. The new DIMMs will be compatible with some of the current as well as upcoming server platforms featuring Intel Xeon and other processors.

    Announced by Crucial this week are the new DDR4 LRDIMMs, RDIMMs, VLP RDIMMs, ECC SODIMMs and ECC UDIMMs rated to operate at 2666 MT/s interface speed with CL19 19-19-38 timings and at 1.2 V. The modules are available in 4 GB, 8 GB and 16 GB configurations and are aimed at less memory-dense server configurations. All the new DIMMs are powered by Micron’s 8 Gb DDR4 ICs made using 20 nm process technology, just like their DDR4-2133/2400 predecessors.

    Specifications of Crucial's Server DDR4-2666 Memory Modules
      Module Capacity Latencies Voltage Height
    ECC SO-DIMM 4 GB, 8 GB, 16 GB CL19-19-19-38 1.2 V 30 mm
    ECC UDIMM 31.25 mm
    LRDIMM
    RDIMM
    VLP RDIMM 19 mm

    Increasing DDR4 interface speed from 2400 MT/s to 2666 MT/s amplifies theoretical peak bandwidth by 11% to 42.6 GB/s for a dual-channel memory sub-system, to 85.3 GB/s for of a quad-channel memory sub-system as well as to 127.9 GB/s for a six-channel memory sub-system. In any case, an 11% performance increase in bandwidth-hungry workloads without any rise of power consumption is a tangible benefit for many servers. On the other hand, it is noteworthy that to increase interface speeds to 2666 Mbps, the module maker also had to adhere to JEDEC specifications rise its CAS latency from CL15/CL16 and CL17 (DDR4-2133 and DDR4-2400) to CL19, which diminishes the latency performance benefits of higher clocks.

    Suppliers of server-class memory announce their products well ahead of their high-volume availability because CPU developers and makers of actual servers have to validate DIMMs before they use them in commercial machines. The situation is a bit different today. Officially, Intel’s current-generation Xeon E5 processors featuring the Broadwell-EP cores are compatible only with DDR4-2400 or slower DIMMs. However some OEMs offer Broadwell-EP machines that can officially support DDR4-2666 for lower memory density servers. Meanwhile, Intel and other manufacturers plan to introduce next-generation server platforms (such as Purley/Skylake-EP) that officially support new DDR4 configurations in 2017 and before those machines hit the market, new DIMMs need to pass a variety of validation process.

    The new server-grade DDR4-2666 memory modules from Crucial are available for purchase now. Their exact prices depend on volumes and negotiations between Crucial and its customers.

  • What Happens When a Nobel Prize-Winning Scientist Retracts A Paper? (Slashdot)
    An American scientist who won the Nobel Prize for chemistry just retracted their latest paper on Monday. Professor Arnold had shared the prize with George P Smith and Gregory Winter for their 2018 research on enzymes, reports the BBC (in an article shared by omfglearntoplay): It has been retracted because the results were not reproducible, and the authors found data missing from a lab notebook... "It is painful to admit, but important to do so. I apologize to all. I was a bit busy when this was submitted, and did not do my job well." That same day, Science published a note outlining why it would be retracting the paper, which Professor Arnold co-authored with Inha Cho and Zhi-Jun Jia. "Efforts to reproduce the work showed that the enzymes do not catalyze the reactions with the activities and selectivities claimed. Careful examination of the first author's lab notebook then revealed missing contemporaneous entries and raw data for key experiments. The authors are therefore retracting the paper." Professor Arnold is being applauded for acknowledging the mistake -- and has argued that science suffers when there's pressures not to: "It should not be so difficult to retract a paper, and it should not be considered an act of courage to publicly admit it... We should just be able to do it and set the record straight... The very quick and widespread response to my tweets shows how strong the fear of doing the right thing is (especially among junior scientists). However, the response also shows that taking responsibility is still appreciated by most people." Those remarks come from a Forbes article by the Professor of Health Policy and Management at the City University of New York. His own thoughts? What the heck happened with scientific research? Exploring, making and admitting mistakes should be part of the scientific process. Yet, Arnold's retraction and admission garnered such attention because it is a rare thing to do these days... If you need courage to do what should be a routine part of science, then Houston and every other part of the country, we've got a problem. And this is a big, big problem for science and eventually our society... [T]ruly advancing science requires knowing about the things that didn't work out and all the mistakes that happened. These shouldn't stay hidden deep within the recesses of laboratories and someone's notebook.

  • Corsair Announces White Color Option for RM750x and RM850x Power Supplies (AnandTech)

    Corsair has announced a new color option for the RMx series power supplies, Arctic White. Readers with a watchful eye may remember that a while ago the company brought out a special edition of the RM1000i PSU in white. Now by popular demand, Corsair has made this a standard option for two of their PSUs, the RM750x and RM850x. 

    The newly redecorated power supplies are otherwise identical to their existing black-painted counterparts. This means they have fully modular cabling which can minimize the amount of wires users need to use, and see, in their cases allowing for a cleaner look. The cables come already individually sleeved in white with black connectors using three layers of paracord for each. Also something of note, one will find in-line capacitors on the ATX, EPS12V, and PCIe cables which Corsair says helps reduce ripple and noise, and improve voltage regulation.

    Features of the RMx series include a Zero RPM Fan Mode, where the rifle bearing 135mm fan sit idle during light to medium loads, only spinning up with heavy loads or at a specific temperature. On top of that The RMx line carries an 80 Plus Gold certification for efficiency, uses 100% all Japanese capacitors rated to 105C, and provides owners with a long 10 year warranty.

  • Plasma: A Safe Haven for Windows 7 Refugees (KDE)

    A fully functional Plasma desktop with a Windows 7 theme.

    Microsoft will stop providing updates for Windows 7 on January 14 2020.

    There won't be any more patches that correct bugs or even dangerous vulnerabilities. This will leave Windows 7 users exposed to all sorts of bad stuff. But that is not a huge concern for Microsoft. With this move, Redmond hopes to encourage users to upgrade to Windows 10.

    But why should we care? Maybe because Windows currently holds 77% of the global desktop market share (all Linux desktops combined hold less than 2%). Of that 77%, nearly 30% belongs to Windows 7. That is nearly a billion people still holding on to Windows 7 because they are resisting the move to Windows 10. Apart from the natural human resistance to change, Windows 10 has earned a bad rap as an operating system that will gladly leak your data back to Microsoft and lace your desktop with intrusive advertisements as a matter of course.

    Helping people regain control over their systems and protecting their data is precisely what Free Software communities do best, making this the perfect opportunity to help Windows 7 users upgrade to something much better: To the Plasma desktop!

    How you can help

    We need you to help convince Windows 7 users to move to the Plasma desktop. We have set up a task where we are brainstorming ideas, advice and resources. You can contribute your thoughts too. Get your KDE Identity today and join the conversation.

    You can also join the Promo team live on Matrix and help us run this campaign.

    Or fly solo! Talk to your friends, family, classmates and colleagues. Even if you convince just one person to make the transition to any Linux-based system, you will have done something valuable and helped the FLOSS movement.


    The Windows 7-like theme shown above was put together (from many parts created by many generous contributors) by Dominic Hayes, creator of Feren OS, a cool-looking Ubuntu-based Linux distro aimed squarely at end users. Check it out!

    Dominic used the following elements to re-create the look and feel of the desktop:

    Plasma Theme: Seven Black
    Window Decorations: Seven Black
    Application Style: gtk2
    GTK Theme: Windows Se7en by Elbullazul
    Icons: Darkine
    Colours: Breeze Light

  • Acer’s Announces Predator Gaming Displays with Tobii Eye-Tracking Technology, Up to 240 Hz Refresh Rate (AnandTech)

    Acer has introduced three new Predator gaming monitors equipped with Tobii eye tracking technology at this week's IFA trade show in Berlin, Germany. The new screens are the first gaming displays to incorporate sensors from Tobii, but apart from them, they also offer very high refresh rates as well as NVIDIA’s G-Sync dynamic refresh rate technology.

    The Tobii EyeX technology was first demonstrated at CES 2013 (at the time it was called Tobii Gaze) as an alternative means of input from the traditional mouse or keyboard. The EyeX sensor is equipped with IR LEDs and an RGB camera to track eye positions and gaze points, where the EyeChip SoC as well as the EyeX software use the data from those sensors to control cursor in Windows or camera orientation in games. The polling rate of the EyeX sensor is 60 Hz and typical eye to application latency is specified to be around 15±5 ms. Tobii’s tech is compatible with Microsoft’s Windows Hello and typical Windows apps.

    While the eye tracking technology can speed up interaction with certain programs and even make life easier for people with disabilities, developers of software compatible with EyeX are primarily focused on games. In fact, there are around 40 games that support Tobii’s EyeX eye-tracking already (including Deus Ex: Mankind Divided and Tom Clancy’s The Division). Given the current positioning of the technology, it is absolutely logical for Acer to integrate the EyeX sensor into its Predator displays.

    Initially, Acer will offer three gaming monitors with built-in eye tracking: the Predator Z271T, the Predator XB251HQT and the Predator XB271HUT. All three displays feature NVIDIA’s G-Sync technology, but the manufacturer does not reveal exact dynamic refresh rate ranges. As for other peculiarities, all three monitors feature at least one DisplayPort 1.2 input as well as distinctive design with red and black color scheme.

    The Acer Predator Z271T is based on a curved 27” VA panel with FHD (1920×1080) resolution and a 144 Hz maximum refresh rate. The product will be available in EMEA in October with prices starting at €799.

    Meanwhile the Acer Predator XB251HQT features a 24.5” TN panel with FHD (1920×1080) resolution, a 240 Hz refresh rate, and an ultra-thin bezel (which Acer calls ZeroFrame). The pricing and availability timeframe of this one remain unknown at this point.

    Finally, the Acer Predator XB271HUT has similar design to the XB251HQT (so, it has similar controls as well as the ZeroFrame ultra-thin bezen), but uses a 27” TN panel with WQHD (2560×1440) resolution and a maximum refresh rate of 165 Hz. Expect this display to be available sometimes in December for €899 in Europe.

    The monitors are not exactly affordable, but it's worth keeping in mind that the EyeX eye tracker costs $140/€119 when sold separately, and the displays feature rather high refresh rates along with G-Sync. Otherwise the integration of eye tracking into gaming monitors is an interesting move in general and a way to differentiate Predator displays from competing products. So it will be interesting to see whether the new screens will become popular among gamers, and how much of that market is willing to pay the price premium for the functionality.

  • G.Skill Announces Trident Z RGB DDR4 Kits with 16 GB Modules, Up to 128 GB (AnandTech)

    G.Skill has recently launched new Trident Z RGB memory kits, this time aimed at Intel X99 platforms, and following the RGB trend they give owners of high-end desktops an opportunity to customize the look of DRAM inside their machines. This is also the launch where the company introduces its first 16 GB memory modules with programmable LED lighting.

    The Trident Z RGB memory modules feature programmable LED lightbars and can change their colors in accordance with user’s demands (G.Skill offers special software to customize lighting effects), providing the ability to modify the look of a PC on the fly. G.Skill first announced its Trident Z RGB memory modules in late 2016 and started to sell them early in 2017. Initially, G.Skill’s Trident Z RGB dual-channel kits were only focused on Intel’s Z270-based platforms and contained 8 GB DIMMs running at up to DDR4-3866 MT/s. Going forward, G.Skill will offer 16 GB Trident Z RGB modules in both dual-channel and quad-channel kits.

    Just like the Trident Z RGB 8 GB modules, the Trident Z RGB 16 GB DIMMs are based on Samsung’s 8 Gb B-die memory chips made using 20 nm process technology. The 16 GB modules will run at DDR4-2400 to DDR4-3866 with CL14-18 latencies at 1.2 V or 1.35 V, depending on the kit performance. The Trident Z RGB fully support Intel’s XMP 2.0 as well.

    G.Skill’s fastest dual-channel Trident Z RGB 32 GB (2×16 GB) kit will run at 3866 MT/s with CL18 18-18-38 timings. RGB commands a premium, so while the company’s fastest DDR4 kits (rated for DDR4-4266) are not RGB, the new modules are still a very high data rate for 16 GB modules. As for the fastest quad-channel kits, G.Skill now offers the Trident Z RGB 64 GB (4×16 GB) rated to operate at 3600 MT/s with CL17 19-19-39 latency settings as well as the Trident Z RGB 128 GB (8×16 GB) DDR4-3333 kit with CL16 18-18-38 timings.

    While these kits are aimed at Intel systems, we would assume that qualification on Ryzen systems will be an ongoing process. G.Skill has just sent us a 2x8GB DDR4-3200 C14 kit of G.Skill FlareX (non-RGB) modules for our Ryzen testing, so it's clear that G.Skill (and others) will have AMD qualified kits in their roadmaps. Motherboard manufacturers typically have memory qualified validation lists on their websites for each motherboard, showing which modules have been confirmed to work. Initially it was hit and miss on DRAM qualification with the launch of Ryzen 7 due to timing, but most vendors are falling into place with appropriate BIOS updates.

    G.Skill traditionally does not announce MSRPs for its memory modules, due to the volatility of the DRAM ICs, but given the fact that DRAM pricing is generally increasing, expect the new Trident Z RGB kits to be priced at high levels. Moreover, since it is not easy to handpick 8 Gb chips for high-speed 16 GB DDR4 memory modules, expect the manufacturer to charge a premium for kits that use high-capacity DIMMs. As an example, right now G.Skill offers 32 GB (4×8 GB) DDR4-3600 and DDR4-3866 kits without RGB for $410 and $460, respectively.

  • Using Trusted Boot on IBM OpenPOWER servers (IBM Developerworks)
    IBM OpenPOWER servers provide a firmware level security feature known as Trusted Boot. Trusted Boot helps defend against a boot code cyberattack by helping to verify that your server is running only authorized firmware. Integrity of your firmware is vital to the security of your system. Trusted Boot works by taking measurements of the executable boot code as the server boots and recording these measurements to a dedicated hardware security module known as the Trusted Platform Module (TPM). Together with a process known as remote attestation, you can use the data in the TPM to verify the integrity of your server's boot code.
