MIT Discovers Third Kind of Magnetism

[Guest]

There exists out there a 4th kind of Magnetism, it is called crapmagtism, an example of this Micorsoft's attraction to the most Crappy UI the world has ever seen in Windows 8! Time after Time, the marketing terds at M$, show that this 4th kind of Magnetism rules inside the Halls of the house that got a lucky break from IBM!

HDDs are a nearly dead technology. Spindle speed pretty much only helps with seek time, and has only a moderate effect on drive throughput. SSDs offer .1ms (or less) seek speed, while a 15K RPM drive offers ~5ms seek time at the cost of a lot of heat, noise, and power. Within the next 5 years we will see a near abandonment of HDDs in the server markets, and we are already seeing SSDs take over as system drives. HDDs only really have a place in larger enthusiast systems for bulk storage. I know I am looking at getting a pair of 3TB drives for my system this spring, and I fully expect these to be the last traditional HDDs that I ever purchase for myself. SSD prices are dropping like a rock, and we are expecting to see 1TB mainstream, and 2TB enthusiast drives to his the market by the end of 2013, so in 5-7 years when my big HDDs need replacing there should be some 'affordable' 4+TB drives available.
Think of it this way, all manufacturers are having QC issues at 1TB per platter, and HAMR tech will help reliability, but is only going to make drives more expensive, hot, and power hungry. Meanwhile, SSD manufacturers can currently cram 1TB of storage in a laptop-sized drive, and with the die shrinks next year they will be able to fit 2TB in the space of a laptop drive, which is something that HDD manufacturers cannot do. SSDs win on heat, density, seek time, throughput, and even reliability in most applications. You do pay a premium for it, but considering you can already find deals on SSDs for ~50 cents per GB, it will not be very long before HDD manufacturers will be forced to either move to hybrid drives, pure SSDs, or simply close up shop entirely.

Platter based HDD's won't be going away for a very LONG time. Their cost per MB(GB/TB) of storage is simply too low for SSD to ever compete against, as SSD's become cheaper so too do HDDs. HDD"s also have a far greater (by a few orders of magnitude) number of write cycles available to them, chances are the mechanical arms or motor will have problems before the media does. Finally in an enterprise environment raw disk speed is rarely a concern, SAN technologies and advanced file systems (ZFS) have the vast majority of data being read from memory and not directly from disk.

Enterprises create storage tiers based on usage. SSD's are now being used as Tier 1 storage, critical data that needs to be read / written immediately is kept there. Tier 2 tends to be faster expensive 10~15K SAS or FC disks, this is were data that is important but not critical resides. And finally Tier 3 is large slower 7200 RPM SAS / SATA disks, this is where archive and user data exists. Utilizing these methods enterprise systems can optimize and balance the costs for capacity and capability.

What SSD's have done is encroached upon Tier 1 / 2 disks, they've replaced Tier 1 entirely and the older Tier 1 disks have become Tier 2. I foresee in the not too distance future having only two storage tiers (three if you count off site tapes). Tier 1 being SSD arrays and Tier 2 being large capacity HDD's for archive / bulk data. Remember it takes ~10 256GB SSD's to provide the same raw capacity as a single 3TB SAS / SATA drive. When viewed from an engineering perspective you can see that storage density and capacity greatly favor mechanical disks. Hybrids are useless in enterprise IT, they rely on analyzing a OS's storage patterns to try to cache data on the SSD component. In IT there won't be an "OS" disk, their will be a virtual HDD image that the OS boots from and that image will be stored on Tier II storage as part of a large virtual environment. The storage processors are what do the caching and usage analysis and determine what goes where.

[citation][nom]wannabepro[/nom]Interesting.Now please actually use it unlike so many 'break through(s)' that get thrown under the carpet and never heard of again.[/citation]
What's stopping you from doing it? Or do you just prefer to complain and let others do the work?

Engineering VS Physics:

The further removed a concept is from a particular scientific discipline the less likely it is to be of any use in the short-term.

We are all composed of molecules but understanding quantum fluctuations really doesn't contribute advances in flu medication.

This would actually make the fourth magnetism discovered. The third already belongs to animal. *rimshot*

Western Digital is hoping to gain an edge in the enterprise hard drive market by rolling out helium-filled, sealed drives.

The company's Hitachi GST subsidiary is apparently planning to introduce the drives in Q4 2013 and trump Seagate's market share in this segment, according to market research firm IHS.

Sealing the drive and filling free space with helium would enable Hitachi GST to increase the density on hard drive platter, since the gas has a nonreactive nature and lower density than air. IHS wrote that helium is "thought to improve the speed of the HDD tracking arm, enhance drive performance through faster spinning of the drive, and eliminate mechanical issues like noise, vibration and turbulence", in addition to "a more uniform temperature on the platter to raise quality" and better protection for the "coating of the hard disk head and disk to lengthen the life of the drive."

IHS said that it expects WD to create 5 TB HDDs to target enterprise market segments, while the technology could achieve up to 6 TB capacities with current PMR technology. The firm believes that "the market for helium-filled drives will climb from virtually zero in 2012 to more than 100 million units in 2016, especially if the high costs of production are brought down."

[citation][nom]sacre[/nom]Take everything with a grain of salt. Nearly every year for the past 15 years i've been seeing articles come out about "3d transistors" and "liquid CPU's" and "laser cpus" and "aids almost cured?" "Cancer cure around corner" "this" "that" "this"I'm sure its all adding up to something, but 3/4 of these are incomplete studies and 3/4 of them end in failure.Just like this, we won't hear about it again for another 5-10 years.[/citation]

Well that mystical 3D transister tech is in Intel's Halswell architectures coming out later this year. Fiber Optics are also making their way into motherboards more and more.

[citation][nom]eodeo[/nom]I heard that Apple discovered this two years from now and sues original researches as copy cats. I mean, clearly Apple should be granted another 1b$ for their effort.[/citation]

TROLL much?

3d transistors... Like the trigate intel is putting on the ivy bridge? Laser cpus... ok, no laser cpus, but some optical companies had a lot of advance in advanced ASPs using optic processing instead of converting light to signal them processing it...

You really think we are not advancing?

As with everything, there's plus, minus and spin. Nice that they noticed... finally... the flux in the middle, between anode (north pole) and cathode (south pole)... which ultimately describes a (perfect) sphere... from a higher dimensional point-of-view... and a toroidal form as it orbits. Welcome to the universal law of three. Georges Ivanovich Gurdjieff described it ("it" has been known a VERY long time) over 50 years ago with reference to the "common-cosmic ansanbaluiazar" which is "everything coming out of everything (and interacting) and returning again at its ends." But physicists are not trained in meta-physics.

My guess is someone from the future gave the scientists the model for this because they needed to trade for supplies to repair their ship to return to the future.
