Toshiba Unveils World's First FC-MAMR HDD: 18 TB, Helium Filled (anandtech.com) 147

Toshiba this week announced the industry's first hard drive featuring flux-control microwave-assisted magnetic recording (FC-MAMR) technology. The new MG09-series HDDs are designed primarily for nearline and enterprise applications, they offer an 18 TB capacity along with an ultra-low idle power consumption. From a report: The Toshiba MG09-series 3.5-inch 18 TB HDD are based on the company's 3rd generation nine-platter helium sealed platform that features 18 heads with a microwave-emitting component which changes magnetic coercivity of the platters before writing data. The HD disks are made by Showa Denko K.K. (SDK), a long-time partner of Toshiba. Each aluminum platter is about 0.635 mm thick, it features an areal density of around 1.5 Tb/inch2 and can store up to 2 TB of data. The MG09 family also includes a 16 TB model which presumably features a lower number of platters (based on the same performance rating).

For modern enterprise and nearline 3.5-inch HDDs, Toshiba's MG09-series drives uses a motor with a 7200-RPM spindle speed. The HDDs are also equipped with a 512 MB buffer and are rated for a 281 MB/s maximum sustained data transfer rate. Unfortunately, Toshiba has not updated the random access performance of the new products, though it is likely that their per-TB IOPS performance is lower when compared to predecessors. The manufacturer will offer its new drives both with SATA 3.3 (6 Gbps) and SAS 3.0 (12 Gbps) interfaces as well as a selection of logical data block length.

One of the noteworthy things about Toshiba's MG09-series FC-MAMR HDDs is their power consumption. In active idle mode, they typically consume 4.16/4.54 Watts (SATA/SAS models), which is considerably lower when compared with Seagate's Exos X18 as well as Western Digital's Ultrastar DC HC550. As far as power consumption efficiency at idle (large hard drives could spend plenty of time idling) is concerned, the 18 TB MG09 is an undeniable champion consuming just 0.23 Watts per TB (in case of the SATA version). Meanwhile, the new drives are rated for 8.35/8.74 Watts (SATA/SAS SKUs) during read/write operations, which is higher when compared to the DC HC550 as well as predecessors from the MG07 and the MG08-series.

    First: Watts per TB at idle. Does this metric make any sense? Idle power of HDDs seems to be independent of their capacity.

    Second: There is no indication or estimation of price. SSDs are typically 4x more expensive per GB (capacity), although they are much better for IOPS. The price of storage has stagnated lately, see for example this plot [jcmit.net]. Will they continue decreasing the price per GB(typically by providing larger units, as it is the case) or will it remain similar?

    • First: Watts per TB at idle. Does this metric make any sense?

      It's relevant if you have shedloads of disk online. Most storage probably sits idle most of the time, so that's the power state you're most concerned with.

      Sure it makes sense. If I am using 18 drives each of 1 TB or one drive that's 18 TB and each drive is using the same amount of energy it should become obvious which is more efficient for long-term storage.

          Anal footing? Eww, that's nasty, especially without an enema first.

          Nope, but I have been in million square foot data centers where the cooling budget alone was larger than the electrical usage of entire towns. Still surprises me in these days where cloud computing brings in so much money that suppliers can't spend it all that this needs to be spelled out for some supposed "nerds". Makes me wonder if some of the lower-UID accounts haven't been taken over by their grandkids.

    • by AmiMoJo ( 196126 )

      It all depends on your use for the drives. If it's nearline storage then idle watts is very important since most of the time the disk will be idle. If it's online storage getting hammered 24/7 then maybe you won't be buying this type of drive anyway, it's not really designed for that kind of use.

      For nearline and offline storage price per GB is far more important than the kind of performance gains seen with SSDs. They typically get large chunks of data written to them serially. They are the kind of thing use

    • " Idle power of HDDs seems to be independent of their capacity."

      In any one family, you get different capacities by adding platters and heads. So the power consumption when the spindle is not rotating is made up of a fixed amount for the board, and a variable amount for each head and tranceiver.

    Jesus Christ the amount of complainers on the site never ends. You can tell the audience here has aged out of technology and moved onto the old man phase where everything they don't understand is new and scary. Massive hard drives using helium inside? Years ago people would be excited about the idea. Tesla is the perfect example. An electric car that runs Linux under the hood? Oh not on slashdot, people here absolutely hate Tesla for some reason. Bitcoin is another good one. Amazing technology written by an anonymous person that is making headlines daily. But on slashdot its the tired smug comments about tulips on every single story like clockwork. Maybe the mods should post some new stories about breakthroughs in Metamucil and bifocal lenses to appease the elderly readers.

    • Massive hard drives using helium inside? Years ago people would be excited about the idea.

      But then we got jaded by the years of new technological developments and announcements that we were excited by and which turned out to suck, or to be vaporware.

      Tesla is the perfect example. An electric car that runs Linux under the hood?

      It doesn't. It runs Linux on the dash.

      Oh not on slashdot, people here absolutely hate Tesla for some reason.

      There are at least as many Tesla fans here as detractors.

      Personally, I'm a Musk detractor [exposedbycmd.org]. I have nothing in particular against Tesla itself for its own sake, although they have made some truly embarrassing design SNAFUs.

      • But then we got jaded by the years of new technological developments and announcements that we were excited by and which turned out to suck, or to be vaporware.

        But slightly bigger hard drives every year haven't proven to be vapourware.

          No, but some of them have sucked, with poor write speeds. This doesn't matter so much when they are in a massive RAID, but it matters a lot in most other cases.

          That's a little more exciting than the razor company that found a way to put six blades on their new razor, one more than last years five blade razor...

        Fuck me that's a quality non-partisan headline on that page you linked to.

        Let's deconstruct it, shall we: "elon-musks-spacex-gave-119000-to-congress-members-who-voted-to-overturn-the-presidential-election".

      More annoying to me is the plethora of 7-digit IDs who have no clue why a site that bills itself as "News for nerds, stuff that matters" runs stories on genetically altering sweet potatoes, supplying shelters with power from a locomotive, or the theft of a million pounds of maple syrup.

  • Probably this is not as much a problem for a metal hard drive case as it is for latex balloons, but is there an issue with helium leakage I wonder?
    • by cusco ( 717999 )

      There'd better not be, 7200 RPM drives can build up a lot of heat fast.

    • These days there are coatings that will contain helium for a long time. They aren't free, but they do work.

    • by JoeRobe ( 207552 )

      I wonder the same. Helium can be a pain to keep in one place for years on end (of course depending upon wall thickness and pressure). I'm curious why they chose He in the first place. Argon is easier to handle, nearly as inert, and abundant.

      That said, I'm sure they've thought about it and there's a good reason why they don't go with Ar.

      • by tragedy ( 27079 ) on Thursday February 25, 2021 @10:00AM (#61098910)

        Argon is easier to handle, nearly as inert, and abundant.

        It's not about it being inert. It's about density. Lower density gases provide less air resistance while also providing better heat conduction. The heat conduction thing may seem counterintuitive, but argon, being a denser gas, is actually a better insulator than nitrogen and oxygen, which are also better insulators than helium. So, basically, a helium filled drive spins with less resistance than one filled with argon or regular air and the internal components stay cooler. Hydrogen would be even better in that regard, but it's even harder to contain and hydrogen infiltration also makes metals brittle, etc.

        If eliminating heat is not an issue, then a vacuum would theoretically work best for avoiding air resistance, but traditionally aerodynamic effects are used to avoid head crashes as well. I don't know if that's still a consideration in these drives, but I imagine it still is, so a vacuum probably won't work. So, all these factors leave filling with helium at normal air pressure as probably the best option.

        It is possible that some of these factors have changed in hard drive design. So any other information anyone has is appreciated.

          Don't the drive heads "float" on an air cushion induced by the turbulence from the spinning drive? That's why drive heads crash if the drive spins down before they are parked safely. I think that would rule out a vacuum drive as well, heat issues not withstanding. I could be misremembering though.

        • by parker9 ( 60593 )

          Does 'ideal gas law' mean anything to you?

      • I was curious so I looked into it. The reason to chose helium seems to be that you can use it at lower pressure, reducing friction and turbulence from the platters spinning. I didn't look into exactly how argon behaves differently in similar conditions but physically be has a lot different properties at the same temperature and pressure and I suspect those properties rather than chemical inertness are why use helium over other gasses or the best vacuum you can manage to seal.
  • How many Libraries of Congress can it hold?

  • As far as I know helium is very difficult to contain and e.g. has to be refilled in MRIs on regular basis, so if it's vital for this HDD to function they might have a limited lifetime.

    • by kenh ( 9056 )

      It's a mechanical drive - it already has a limited lifetime due to it's reliance on moving parts.

    • MRIS are refilled because the liquid helium is a consumable coolant which is designed to evaporate. Different mechanism than the gas permeability of steel or aluminum.

      • by ceoyoyo ( 59147 )

        Modern superconducting MRI scanners recondense their helium as it boils off. They still lose some though, and have to be topped off occasionally.

    Is it ZFS-compatible?
  • Every drive comes with a free tether! Now your data can truly be in the cloud!

  • Digital Development Corp. of San Diego built head-per-track disks in the 1960s-/70s that operated in a helium atmosphere. The enclosure was a metal can bolted to an aluminum baseplate, with a sealing gasket. A small gas cylinder and regulator were attached to the baseplate (19" rack mount), and a couple of valves kept the interior pressure to slightly above ambient. If I recall correctly, DDC stenciled their own part number onto the cylinder, though it was industry standard (e.g. Matheson).
