New Water-Cooled Hard Drives Coming

Posted by Zonk on Sat Aug 04, 2007 04:18 AM
from the can't-stop-the-fire dept.
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.'"

[+] Terabyte Hard Drive Put To the Test 376 comments
EconolineCrush writes "As a technical milestone, Hitachi's Deskstar 7K1000 hard drive is undeniably impressive. The drive is the first to pack a trillion bytes into a standard 3.5" form factor, and while some may argue the merits of tebi versus tera, that's still an astounding accomplishment. Hitachi also outfitted the drive with 32MB of cache—double what you get with standard desktop drives—making this latest Deskstar a leader in both cache size and total capacity. That looks like a great formula for success on paper, but how does it pan out in the real world? The Tech Report has tested the 7K1000's performance, noise levels, and power consumption against 18 other drives to find out, with surprising results."

    Several people have already commented that they don't see the need for this, which is what I was going to say
    (because the hum of my harddrive is much less than the hum of several other things in my apartment, and much much less than I-5, which is just outside my window)
    But I imagine that there is still a few niche markets where the additional cost would be worth it. Is this designed for computers that are to be used in operating rooms, or research labs, or some other exotic locale where noise has to be kept down to a minimum?

        Very accurate. 30 db is about 4x more powerful than 24 db (i know you said 25, but when working with decibels you want to work in units of 3). The inverse square law says that power is inversely proportional to square of distance. Therefore, something that is 4x as powerful sounds the same at sqrt(10^2 * 4) = 20 meters

        BTW, I believe 30 db is a soft whisper at 5 meters, not 10. So something at 24 db would sound like a whisper from 10 meters - still, not bad.

    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)...

    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?

    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.

        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!

    • 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?


      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?

        • Tell me, how exactly does one abuse an observation?


          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.

            The average PC is a low-end desktop that probably barely even peaks at much over 100W of power draw.

            There is no law of physics that demanded this increase in power consumption.

            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.

          HEAT? put a fan across the drives make a GIANT difference in drive longevity.
          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).

        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.

      The biggest factor in keeping them down to acceptable levels is just mounting them on soft rubber grommits.

      You also need fans to keep them cool. After the CPU and GPU, the hard drive is the hottest thing in your computer. Especially in drive arrays or servers, they can heat up extremely quickly with sustained usage.

      If this works like it sounds, then it will not only quiet the drive, but cool it more efficiency and allow less external cooling (fans), which should quiet things down even more.

            Right now it's a novelty price point issue. There is no way they'll stay above $300 for a 32gb drive for very long. Give it a year or two and you'll probably see just that. Considering you can get 16gb in a flash drive a laptop flash drive or a 3.5 HD shell has a silly amount of empty space which can be used to increase capacity and performance. There is no reason they couldn't set up and internal RAID like arrangement to be able to saturate a SATA connection. Right now we just have to wait for market and Mooore's to work their magic on price point.

            If that is too much to ask for then they just need to set up rows of SATA/USB ports that just let me plug 10-15 memeory sticks straight into the mother board so that a standard RAID solution can be used.
