        You've got to admit that the innuendo in that headline is... um... somewhat unsubtle.

        To be honest, I always suspected the term "hard drive" was invented as a sick inside joke by computer geeks, (along with a few other very suspect phrases).

        But what really convinced me was when I went to South Africa and discovered that a 3.5" floppy disk is known over there as a "stiffy disk". Ostensibly, the original idea was to differentiate them from the older 5.25" floppies, but you've got to admit that whoever came up with that one must have known what he was doing.

        I'm not usually one to laugh at blatant innuendo, but the first few times I heard that phrase being used, it absolutely cracked me up - not just for the phrase itself, but for the fact that no-one else seemed to get the joke. To them the phrase is completely natural: A South African computer geek can get away with telling people that he's got a stiffy in his pocket, and it won't even raise a smirk.

        (having said that, it's been a while since I've used a stif... uh, a 3.5" floppy, so I can't be sure the phrase is still current - SA readers, feel free to correct me)

      SATA is the speed of the bus from the hard drive, not the actual drive. You'd currently need a RAID cluster of drives to fill the SATA bus.

      And hard drive speed does matter, a huge amount. Unless you have a crapload of RAM and everything you use is cached, 90% of the time you spend waiting for programs to start up or large files to be read is waiting for the HD to read the data. A faster HD can make a computer feel much snappier than a slow one.

      Hard drives are pathetically slow. A seek takes 10 milliseconds, that's a factor of almost a million slower than a random memory access. The biggest noticeable delays (boot up time, firefox load time, open office load time, etc.) are all caused by the slow hard disk. Transfer speeds, which are now approaching 50MB/sec, are good enough. And size is still going up: two years ago 120 GB, one year ago 250 GB, this year 400 GB. No sign of slowing.

        Not meaning to be (overly) pedantic, but that's not wear. Wear is caused by bits rubbing over each other.

        This is not just a semantic difference. The failure modes of silicon chips are mostly diffusion limited - that it, the metal conductors expand, the pn junctions become more diffuse, vacencies develop in the silicon, and so on. The failure mode of a part which wears is generally that the wear causes a mechanical weakness in a part till it breaks, bends, or is otherwise no longer functional.

        This difference is reflected in the time to failure of different devices. Electronics show a bathtub curve - essentially, manufacturing defects show up in young failures, then after a period (around 8 - 10 months), there is no intrinsitic source of failure other than the (slow) diffusion limited modes, so there number of devices failing drop very low, until that mode dominates, at sometime around 8-10 years after manufacture.

        Mechanical parts also show young failures, but, due to wearing, they do not last as long, and the rate of failures does not drop as low. The exact duration is determined by the type of use of the part. For example, this motor here *clunk* has bushes and brushes that have a design life of 1 months constant use, which translates to about 4 years with typical uses patterns. On the other hand, the motor in a washing machine is rated for something like 2 years constant use. The washing machine motor has bigger bushes and brushes, which are designed to last longer.

        I could go on, but a) it gets boring rapidly, and b) I'd have to did out some notes on it, and cba.

        In 10 years with computers, which gives experince with devices up to 20 years old, I have seen 1 case of failure in a componant over 3 months old that was not caused (directly or indirectly [0]) by mechanical wear.

        Having said all that, Flash memory is not as reliable as most electronics, as it has a particular structure that causes insulator breakdown after around 1000 writes. But that's not _really_ wear, although I'm told it has a similar failure profile.

        Not moving parts does not translate to no deterioration, but it _does_ mean no wear.

      Why are there slashdotters that believe memory chips will replace hard drives on a large scale any time soon?

      2TB is the addressing limit of that standard, not the amount of memory they will have. 2TB memory cards will take a loooong time to be released, esp. given that 8GB CF cards aren't available, 4GB CF cards are still pretty expensive, if available at all.

      Because flash memory cards follow RAM in costs, I doubt flash drives will replace hard drives any time soon unless you want your hard drive to be as small as your RAM space. Very similar processes are used, and I don't think the cost of making 32MB RAM chips are much different than 32MB solid state chips, because they are very similar in complexity.

        The first round of very fast and very efficient (if also very expensive) flash memory cards large enough to be considered viable hard-drive replacements are coming around now.

Now we have three levels of cache on top of that. Now (excepting certain bits of bloatware *cough cough*) operating systems are not growing in size at the same rate as storage technology.

      Ignore the other people who replied, I don't think they bothered to read the article. The lubricant on the disc surface is just to help protect it from damage (platters are already have a protective layer, but this new one has better characteristics at high speed and is simpler to apply because it doesn't require seperate adhesives).

      The term lubricant probably wasn't the best choice, rather it's just a protective film.

      Supposedly at the high RPMs of top of the line drives, the film currently used can ripple or even spin off entirely after prolonged usage which leaves the disc more vulnerable to head contact or armature resting.

    The oddest materials pop up for load bearing duties.
    "Felt bearings" have been used in the automotive industry for years.

    Especially in rack and pinion steering system where lateral forces are not so high.

    Lubricants for the felt material include oil and graphite powder, or run dry.

    While more durable bearings such as needle roller, bronze sleeve, and teflon bushings, may be the preference of performance applications, ease of fitment, damping ability, and cost, still ensures felt bearings are used today, both in automotive and other industrial machinery. It is very possible, you have owned a car with one or moore felt bearings somewhere in the steering system.

    The properties of synthetic material as a bearing surface have been used and far back as 1950's(and maybe beyond).

    For those who failed chemistry . . .
    The polymer used in this application is a sterically hindered polyester. An ester is a carboxylic acid with some sort of organic group replacing the hydrogen (i.e., O=C-O-CH3 is the methyl ester moiety).

    Bulky groups sterically hinder a molecule, making part of the molecule inaccessible. One very common application is the sterically hindered base, like triethylamine. A normal amine is NH3, but a triethyl amine is N(CH3)3. The effect is that the compound raises a solution's pH, but cannot react with other functional groups easily. This helps prevent side reactions / biproducts.

    t-BOC is one type of a sterically hindered protective group. Generally, protecting groups are removed as one of the final steps in order to get the desired product. This polyester has steric hindrance that protects the ester bond. But the article didn't say how that was accomplished. Adamantanes are another type of bulky group used to sterically hinder a molecule.

    • Well, I bet there are a lot of people who've never failed chemistry who didn't know what a sterically hindered polyester is.
      I'm also sure that there are a ton of smart chemistry students who, thanks to your pedantic "explanation" are no wiser.

      I hope that you don't plan to teach chemistry to anyone who doesn't already know it.
      Not everyone has studied organic chemistry.

    • Uh, that sort of chemistry falls under organic chemistry. Organic chemistry was the third class to take in the chemistry track at the schools I went to, but non chem-majors only needed to take the first two.

      (I didn't write the above comment; just trying to keep the thread from getting too deep)
      Sorry, but anyone who studied (and passed) chemistry ought to know what steric hindrance is. If you're having trouble with my vocabulary, then I'll try to clarify.


      Steric: having to do with space. As in, "I was unable to fit my couch in the Honda Civic due to steric hindrance."
      Polymer: A molecule composed of three or more repeating units. This can be a heteropolymer (more than one type of repeating unit) or a homopolymer (only one type of repeating unit). The repeating unit is called a monomer, and often has an antiquated name. For example, ethylene is the antiquated name of ethene, a two-carbon hydrocarbon with a double bond between carbons. However, polyethylene has no double bonds (because the bonds opened during the polymerization).
      Moiety: A part of a molecule that has a particular functionality. For example, the amino acids each have three moieties: the amino part, the acid part, and the side-group. For proline the amino part is the side group also. Functional groups (amines, esters, acids, alcohols, etc.) are all moieties.

      Are we clear now? Or is that still too pedantic? BTW, I'm not a teacher and don't plan on being one in the near future. There are different levels of understanding of any subject. Just because some people don't know what a molecule is doesn't mean I should define every term when I mention them. To quote H. L. Mencken, "Those who can, do; those who can't, teach."

    Could this be used on engines? I know that oil carries away heat, as well as lubricates, in internal combustion engines.

    If they find a way of coating parts and use some kind of anti-freeze in vehicles, maybe internal combustion engines will last longer. Two strokes could make a come back.

    I've often wondered about the rate of evaporation on fluid-bearing HDs. Running at high temperatures, even the lowest level of evaporation will mean a loss of lubricant over the years. Even inside the semi-sealed chamber of the drive, each on-off cycle will mean that the drive exhales the evaporated lubricant and the cooling pattern of a turned-off drive will mean condensation of lubricant on the inside shell of the case.

    Ball-bearings (well-designed ones at least) can last virtually forever. I wonder if the same can be said for fluid bearings?

    With my hard drive luck, a year seems like a "longer lasting" drive. I've lost more hard drives in the last year than ever - Just being away on vacation (with the computers unplugged), I lost 2 hard drives! (not a complete loss, but the systems acted funny enough that I suspected total failure if I didn't replace the drives quickly)

    One week of being off, for a drive that is not used 24x7, should not kill a drive. I've had drives sitting on a shelf for a year that still work fine. I should not need to setup a 3-drive RAID array simply to get the level of reliability we had a few years ago.

    It is surprising how often improvements in our computer technology comes from relatively mundane sources. For example, much of the reason that Moore's Law has continued to hold is the way that the mechanical engineers have been able to constantly improve our ability to position things accurately. Masks and wafers must be positioned with astonishing (at least to me) accuracy relative to each other in order to allow creation of 90 nm features.
