Disk Drives Face Challenge From Chips

WSJdpatton writes "Researchers are reporting significant progress in perfecting a different way to store data in semiconductors, which could replace one widely used type of memory chip and possibly become a credible competitor to disk drives. The researchers, in a paper being delivered at a technical conference in San Francisco, say they used a novel combination of materials to create prototype phase-change components that are more than 500 times as fast as flash chips, while requiring less than half of the electrical power to record data."

    Today the bottleneck of the whole system lies in the hard drive. This is the only mechanical part (fans excluded) of a computer. It's about time to find a solution for large storage that doesn't depends on an arm swinging and moving back and forward through a fragmented file system....

    It's time to realise that Abble's products are the biggest abomination these days. Just say NO to the dumb iAbble way!!
  2. The real challage is price. by jellomizer · · Score: 5, Insightful

    Hard Disk Drives now are about $0.50 a Gigabyte. Flash is now about $25.00 a Gigabyte. 3 1/2" Floppy disks about $250.00 per Gigabyte. So it is natural for the Flash Memory cards to replace the floppies as they did. Better speed and better cost/Gigabyte. But right now Hard Drive technology is really cheap. If this new design can match prices/gigabyte of a hard drive then the Disk Drives will need a real challenge. Otherwise This new technology may only be a threat to Flash, or used with drives in hybrid mode for faster disk access. But not until then.

    Price is a major driving force in memory.

    CPU Registers are the fastest but most expensive (very small amount is used)
    Cache is the next fastest and the second most expensive. (4 Megs or so)

    Then comes normal RAM Memory Still slower then Cache and cheaper normally systems now have about a Gig or 2 of that.

    If price wasn't a case Computers wouldn't have much RAM but all Cache, or huge amount of registers. But in real life price is the final decision.

    If something is so important that you feel the need to post it on the internet... It probably isn't that important.

    Possibly. If I had to give up a 360G platter drive to put in a 120G phase drive, I'd probably do it - so long as the cost favored the phase drive.

    I'd probably still keep the platter drive for secondary storage and put the OS and critical apps/servers/whatever on the phase drive though.

    I wouldn't pay twice as much for a drive with half the head room though - even if it is 500X faster. That kind of speed (and especially power consumption) may be a big deal for notebooks, but if density is really a problem, the notebooks would probably have to give up a lot more headroom - relatively speaking. We're finally seeing 200G notebook drives, but keep in mind they're tiny compared to your standard laptop drive. If the new phase drives can store the same or more data in the same space, then yeah, I definitely see the end of the platter drive in mainstream use - once the supply outweighs the demand enough to make it financially realistic. If they can put no more than 30G in a notebook drive, then I think it'll take a couple product generations for that to happen.
