Toshiba Develops 0.85'' Hard Disk

onebuttonmouse writes "Toshiba have set a new record for the world's smallest hard disk at a tiny 0.85". Surely this will have some great applications in mobile devices, although the article does not mention power consumption. It'd be great if this made it into the iPod like the 1.5" Toshiba drive that resides in the current models."

      2-3GB on a 0.85" drive isn't much compared to the 30GB+ on a 1.5" drive. That said I wish they'd put more money into developing high density solid state storage devices. 0.85" is cool but it's still a mechanical device with all the inherent problems.

      Try building an IPOD into a pair of headphones. The advantage of compact flash is you can now store enough data for almost any conceivable portable use. Like when did you last listen to 30Gb worth of MP3 without recharging your batteries?

      The role of an iPod formfactor device is to provide a portable repository from which to fill up the wearable media. No an ipod is too heavy to count as wearable.

      The big problem with these disk ideas is that they end up costing a lot - $500 to $200, there is no low end version like there is for flash rom. I typically buy whatever memory is $60 at costco these days, but then again for photography that is easily sufficient, I do not fill up 256K chips before I can reach my laptop.

    This is great for seek times, high speed applications like watching hi-res movies from a hard drive this small could mean smooth tracking through the film without losing audio sync, a problem which affects larger drives (3.5").
    Forget the iPod, this sort of drive would do nicely in a handheld/pocket divx player.

      Could you explain wtf this has to do with access time?
      If you can track to a film with audio sync or not is purely dependent on the container and the audio codec. Ogg or avi mit vbr mp3 can create problems, seek times dont (your blockindey is already in hd-cache, and if you dont jump into an i frame, decoding a lot of b/p frames (up to 11 in mpeg2 up to 100s in mpeg4) will take a lot longer than seek time.

      But even if seek time would be important for that stuff: Your 0.85" hd will have a lot worse seek time than any normal 3.5" drive. Because of the simple fact that you cant fit very powerfull magnets / coils in such a small package.

  5. Re:1 gigabyte flash by HiThere · · Score: 4, Insightful

    Ability to do rewrites to a sector could be significantly different, however. There are recommendations to not format flash to ext3 because of frequent rewrites to the same sectors, which could cause the flash cells to end-of-life pretty quickly, but hard disks don't generally have that problem. (OTOH, neither do vfat systems...not sure about ext2.)

    300 USD might buy you 3GB flash after some rebate crap. By the time this product comes out in 1-2 years, the final price will likely to be less and just below equivalent flash capacity. See what happened to IBM Microdrives vs. CompactFlash... It is not earth shattering invention, just normal evolution. Now 30 GB in that size, that would be somethin'.

    high density solid state storage devices

    Having seen 2 GB USB memory keys starting to become available, I have to wonder what the great advantage is of the microdrive.

    I've heard the memory keys are limited by the number of erase/write cycles (to ~10,000) before they wear out, and also limited to data transfer speeds of about 1 MB/s (although I think USB 2.0 is supposed to be better).

    Unforunately, I didn't see any specifications about the read/write speed for this drive, but if it's going to plug into a USB port then it has no practical advantage over the solid state memory device.

    Is there any other reason you'd want a mechanical device like this over solid state memory?

    What....? Those millions of peoples with iPods seem to be able to power them up and turn them without falling over.

    Current implementations demonstrate the gyroscopic effects aren't a concern (except possible for the engineers designing them). Smaller disks will make it even less so.

    Most of the power used by a hard drive I would presume is used to spin the platters. With a mass and diameter this low, spun at the same rpm as standard drives the power used would be:

    a) huge

    c) miniscule

    China, despite having the world's largest mobile phone market (~250 million users), the growth is now mainly in the lower end of the market, so innovations like these will take a long time to penetrate.
