New Water-Cooled Hard Drives Coming 145

CoolHandLuke writes "NEC and Hitachi are teaming up on a liquid cooling system for hard drives. The goal is to cut down on noise levels while providing more efficient cooling. 'Hitachi and NEC are developing the water-cooled hard drive systems for desktop computers mainly to reduce noise levels to 25 decibels, 5 decibels quieter than a whisper. To do this, NEC and Hitachi actually wrap the hard drive in "noise absorbing material and vibration insulation." According to Hitachi and NEC, the cooling cold plate they're planning to use is the most efficient plate ever used for heat conduction, which means they'll be able to cool the hard drives quicker and more efficiently.'"

  • I believe you mean "quicklier and efficientlier."
  • The obvious market for water cooled CPU's is to achieve maximum performance. While quiet is good for the consumer sector in general do people really find HDD noise annoying enough at 7.5K rotational speeds to justify the extra cost and complexity? And surely those running 15K drives and hyper-fast CPUs for server and high-performance applications already have so much cooling in place that a little extra drive noise makes little difference.

        Personally I've moved to using iSCSI on my desktops. Every single one is booted off PXE and mounts its disks over the network (with very close to native performance; gigabit copes well with iSCSI, and the memory in the iSCSI target machines works nicely as cache). Blessed silence ensues, with care for CPU and PSU fans, the desktops become close to inaudible.

        The server cabinet is slightly more noisy, but with care taken to soundproofing and with sound-absorbing vent channels and the disks mounted on vibration reducing material, it doesnt sound more than modern fridge.

        Adding yet another cooling bus to the desktop sounds like a supremely unpalatable idea. It's much easier and much more reliable to move data over the network than it is to move water around in a computer.

          Although I realize this article is talking specifically about storage devices, consider that some things, such as high-end video cards, need to be local. If you're already doing watercooling to have quiet high-performance graphics, why not add your hard drive to the loop and get rid of a case fan?

            True, if you already do have watercooling it might very well make sense. Altho I'd argue it's slightly different as the graphics will only need the cooling running while they're actively used.

          The problem with this is that it requires you to have another closet or room to store the hard drives.

The latency issues of NFS are gone, and the performance on both small and large files on par with local disks (it is, effectively, a SAN, so I expected the performance to end up around there, impacted a bit by cheapo shared gigabit infrastructure and improved by the utilization of the memory in the servers as cache).

        I have used that site extensively for the design of my computer. It's the quietest PC I've ever encountered.

        Noise is a huge problem these days, and I'd expect it to especially affect the Slashdot readership, since the majority of them are likely to be introverts. Introverts suffer from brain overstimulation all the time. Noise, crowds, situations that require constant attention to multiple variables, push us over the edge and drive us nuts. This is why we are drawn to jobs that require hours of uninterrupted attention, such as those in programming or academia. We find such things calming and are very good at them.

        The effect of PC noise, however, is not one of which I was aware until I was working on my master's thesis and, just as an experiment, put on the noise-canceling headphones I use on planes while I was sitting at my desk writing. They killed the sound of my 3 80mm fans, the 60mm on my video card, and the smaller one on my southbridge. In one shot, I wrote for 6 hours straight, blissfully focused.

        After that, I spent a lot of time and money upgrading my computer to be as silent as possible. I have a fanless PSU. A large, slow Zalman CPU cooler. I replaced the southbridge fan with a heatsink. I have a fanless video card. Air flow is achieved via 2 slow 120mm fans. Hard drives are mounted on rubber grommets.

        All that being said, the computer is still noisier than I'd like, and 100% of the perceptible noise is that of the hard drives (well, CD/DVD drives don't really count, because you don't usually use them). I use only Seagate drives, which seem to be the quietest, but anything that could further reduce the whine (without mounting my drives on surgical tubing, something you can read about at SilentPCReview) would be absolutely welcome.

        Just as the constant whine of an airplane's engines causes you to be exhausted at your destination, the constant whine of fans and other moving parts can exhaust you in front of your computer. I welcome any development to further reduce the noise footprint of today's PCs!

        • After that, I spent a lot of time and money upgrading my computer to be as silent as possible.

          Why in the hell would I want to quiet or cancel out the pink noise from my computer, only to become more aware of the barking dogs, boombox cars, screaming brats, and fighting cats, which I can't cancel out except with the barrel of a gun and a vacation to another very unquiet and unpeaceful place?

      Acutally, yes, I do.

      Its more than noise, however. We don't need a more efficient cooling system, we need a hard drive that uses less power and generates less heat.

      The whole path that desktops are going down (except for the occasional exception such as a mac mini) is one of more power, more heat, more fans, more noise.

      This is, to my mind, the grossest abuse of Moore's law that can be had. Instead, we should be building smaller and lower powered devices. Perhaps it simply reflects how cheap energy is that we choose to build computers this way.

      So now we can build a whole class of hard drives that suck more power from the wall, confident that they won't make as much noise?

      Am I the only one who sees the folly of this?

          Same way you abuse anything else - quantum physics (nuclear power or bombs), chemistry (medicines or nerve gas), arable land (corn for tortillas or petrol additive).

          The abuse that I see here is that we should be smart enough to not abuse our knowledge and resources for short term gains at a long term cost.

          What we do with the evolution in technology is our choice, certainly.

          It was not so long ago that people used to laugh at why you would need a 200W power supply for a computer. Now it seems that 500 watts are common enough, and some are going significantly higher than this.

          There is no law of physics that demanded this increase in power consumption. It was a choice by manufacturers and consumers.

          There are certainly some times when it makes sense to throw the power at the circuitry, but for the most part its just wasted time. To my mind the ideal computer would run at close to 100% CPU utilisation all the time, but the whole system would reduce its power and speed to match the load requirements. Likewise, standby power should be very close to zero - we do this for laptops so much better than for many desktops.

          I guess its my personal ethos showing here. Nothing more, nothing less.

          Anyway, I hope that explains my position on why I think its an abuse. Energy is cheap, but it may not be for too much longer.

          The world really doesn't need a hard drive that sucks more power quietly, at least not for most computers.

          Hopefully in a few short years flash drives will overtake hard drives and everyone wins.

            They're nowhere near as common as enthusiast sites would have you believe, and even in most machines that have them, they're not using anything close to 500W of juice.

            Sure there is. It's the cost of greater computing power, within the limitations of current technology.

            Hopefully in a few short years flash drives will overtake hard drives and everyone wins.

            Flash drives aren't going to replace hard disks in the near future as they are highly unlikely to be able to come close to the same size/cost ratio of hard disks.

              Part of the problem is that many computer power supplies seem to be incapable of running near their rating. As such, builders have adapted by way overspecing the power supply (ie, a "500W" power supply for a computer that might draw 200W max). For some reason, we just accept this.

          You may be interested in reading this article [stanford.edu] and for even more information this paper [google.com]. Apparently Google collects performance/environmental/failure data against their entire computing infrastructure and has over 5 years worth of this data. In this analysis (of likely hundreds of thousands of drives of different types / manufacturers over a long period) they found little to no correlation between heat and failure rate of the drives.

          Power use, well that one you have a choice. Low power and slow. high power and fast. please pick one.
          To better qualify that statement, "slow" and "fast" are only relative to each other, not necessarily a user's experience on a particular application. A high percentage of the time, a "slow" machine will suffice just fine (as per your example).

            The figure shows that failures do not increase when the average temperature increases. In fact, there is a clear trend showing that lower temperatures are associated with higher failure rates. Only at very high temperatures is there a slight reversal of this trend.

        For what it's worth, removing heat with water is inherently more efficient than blowing air with fans, as it is easier to move any given quantity of heat in water than it is to blow it away in air. Electrical usage in, say, heating or cooling systems is significantly lower with hydronics than with air systems, for example.

        Unfortunately in this case they aren't doing away with the fan, just using a smaller one. It would be much cooler (ahem) if they instead could engineer a passive heat dissipation radiato
        • Cooler still if they engineered a thermosiphoning loop, for completely passive cooling with no moving parts and no energy draw at all. Sounds like the temperature differentials at work here might be enough to make such a loop work...

    Hard drives are very easy to cool. The water block plates don't fit snuggly against the uneven surface of the hard drives' sides. But it doesn't matter. The whole drive is still cool to the touch, much cooler than decent air cooling can manage. In short, there really isn't a need for "the most efficient plate ever". And it won't do you much good besides, as last I checked, hard drives are not very flat on the sides or bottom.

    A while ago I saw a study from google [slashdot.org] that said disks running at 40C was most reliable. Cooler drives died faster, and warmer drives died faster. So why does the manufacturer try to cool 'em? Seems to me that reliability increases if you don't keep 'em at 20C like many people do. And 40C is the temperature my 7200RPM disks reach in a normal cabinet (well, actually 35-38C)...
    • I've found out the hard way that hard drives don't like 60C. It's not good when the A/C dies in the server room of a storage company and nobody bothers reporting to engineering or IT that the A/C died.

      Huge pile of dead equipment from that fiasco.

        What I find annoying is getting lm-sensors to work with server hardware.

        I can monitor the temperature and voltages of my home beige box but can't on any of the servers I tried at work- Dell, IBM, HP.
    • Those cool HDs probably were dead, because 20C is around DC temperature and it's unlikely a HD with a working motor will have such temperature. Probably the motor was dead and only the circuit board was working.

      Also these studies are probably focused on next generation HDs, which will have speeds higher than 7.2k HDs used by Google.

    This plays out every time exactly the same way and yet people fall for it every time. Just like SLi, water cooling is unnecessary. It is and has been used for bleeding edge performance *before* the technology is really at that level and certainly before the software is. If you wait 6month's to a year the hardware catches up, doesn;t need water cooling and around that time software begins to emerge that utilizes the new technology. So for 6 months you gain the ability to say oooh look at my watercooled setup that does nothing except maybe pump out high synthetic benchmarks since nothing utilizes it yet. Same with SLi.

    No developer is going to produce for a market that may be 1% of the total market. Once the technology reaches mainstream use (which watercooling and SLi never will) they then begin to utilize it. This has gone on since the days of mainframes, and continues in cycles right up until today... when will people learn?

      Actually, in this case it's needed. Do you think HD manufacturers haven't been making HDs as cool and quiet as they could?

      By wrapping the drives in insulation and using water cooling to give the heat a pathway to escape, they can kill 5 decibels.
      • No, it isn't... that's my point. What it proves is that the technology itself has reached a final limit to stability, sound output, speed, and usefulness. The hard drive has endured in basically the same form for 20+years, it is proven to be one of the slowest subsystems in a modern computer... all the water cooling in the world cannot help that.

        Solid-State drives are arriving, have lightning fast access times, MTBF is becoming less of an issue, and prices are coming down.

        You are the exact type of person fo
        • I think this would be extremely useful and efficient in a data center. Not every hard drive is put into a laptop.

          Solid state storage will take a long time to reach the capacity and performance of hard disks for the same price.

          • Maybe in one or two systems, but would you want to manage that on a large scale? I wouldn't. My data center has over 400 servers in it (Windows and Solaris) Plus a huge SAN, I couldn't imagine adding yet more complexity and possible failure points. Even sealed water-cooling systems tend to need servicing and refilling at some point, and a failure could be catastophic. No thanks, but maybe in smaller data centers or server rooms.

      Actually, I see a "plus" for watercooling in one area: Videocards. You can't just replace the heatsink/fan on these with a larger heatsink/fan to make them quieter in most cases, because of the limited space. My latest build (core2duo w/stock fan and a 7950gt) has the videocard pegged for the loudest device in the case - when I'm gaming. Of course, when I'm not gaming, the machine is very quiet.

      And if I was going to cool the videocard, I'd probably spend the money for a CPU waterblock too. Then use a 12

        XFX do a passively cooled 7950GT [hexus.net]. Including an overpriced factory overclocked one.

        Hopefully we'll see this for the higher end GeForce 8's before long.
      • Again, you are the type who has fallen into this trap and silly mindset. Stop reading the "extreeeme!!1! OC" websites and just think about what you are saying. You are making my point. A videocard that requires watercooling means it is that inefficient or newly designed that it hasn't matured. As the chip process matures you see die sizes shrink and power and heat output reduced.

        You have jumped into a card that is not mature and not produced as efficiently as it could be. The G71 didn't have any temperature
      • You can do it if you want. The GPU fan died on one of my video cards. I took a passive heatsink that originally cooled a Pentium Pro 200 (big sucker) and used some thermal epoxy to glue it straight to the video chipset. Ran a bit warmer than stock, and I lost a couple of PCI slots, but it worked.

    Right now, my main PC has three fans devoted just to keeping my drives cooled.

    My Tivo has long had the lid off and there's a special fan clamped next to it dedicated just to cooling the drive.

    That's four fans worth of noise just for drive cooling, far and away MUCH louder than any other noise in this room.

    If there's a way to keep them cold and quiet, I am in.
    • by Cheeze ( 12756 )
      but really, if you took out those fans, would anything break?

      probably not.

      electronics are fine running hot up to a certain point. just because your drives are hot to the touch does not mean they are out of spec.
    • From section 3.4 of this study by Google of hundreds of thousands of drives: [google.com]

      The figure shows that failures do not increase when the average temperature increases. In fact, there is a clear trend showing that lower temperatures are associated with higher failure rates. Only at very high temperatures is there a slight reversal of this trend.

      Sorry for repeating myself [slashdot.org], I just thought you'd like to know that you're doing your drives more harm than good.

      • by Fweeky ( 41046 )

        I just thought you'd like to know that you're doing your drives more harm than good.
        Unlikely. A few fans probably aren't going to be effecient enough to cool drives much below 30c, but they probably will be sufficient to keep them below 45, where failure rates start to creep up. In a cramped poorly ventilated case outside the context of a nice air conditioned data center, 55c+ isn't uncommon.
    • Drives are often specced to run up to 60 degrees Celsius. However there are enclosures for hardisks which can cool it down without fans, just do a search [google.com].
  • From my own experience with flash drives made by several different manufacturers, my guess would be that they won't make your heat problem go away. I currently use about 10 flash drives on a frequent basis, all either 2GB or 4GB and from several different manufacturers. After writing, say, 1 GB of files to one of them I can tell you it is HOT to the touch. We're talking way more than 30 or 35 degrees C here - more like 50.

    If you used flash for desktop storage right now I suspect a big array of flash drive
  • Didn't google discover that heat isn't a big factor in hard drive reliability? [slashdot.org] This is more about moving waste heat around versus generating less of it.

    I'm all for quiet, though.

Avoid strange women and temporary variables.
