6 Firms Form Holographic Versatile Disc Alliance

Posted by timothy on from the say-that-3879-times-quickly dept.

gardolas writes "'Fuji Photo and CMC Magnentics are two of six companies, who have formed a consortium to promote HVD technology, which they say can be used to put 1TB of data onto just one disc. The consortium say that a HVD disc could hold about 200 standard DVD's, and transfer data at speeds 40 times that of DVD, about 1GB per second.' HVD is being seen as a possible successor to Blu-ray and HD-DVD technologies."

    Well "technically" PC3200 means 3.2GB/sec. But yeah, in practice you only get [anywhere near that] that doing series of uninterrupted perfectly timed 8-byte writes to sequential memory...

  2. 1/10th of a LoC by seizer · · Score: 3, Informative

    The LoC is normally quoted at 10tb.

    according to TFA:

    The consortium said an HVD disc could hold as much data as 200 standard DVDs and transfer data at over 1 gigabit per second, or 40 times faster than a DVD.

  4. Might be worth mentioning... by ibringthelight · · Score: 5, Informative

    From the slashdot article:
    "about 1GB per second"

    From the cnet article:
    "transfer data at over 1 gigabit per second"

    Slight difference there of about eight times...

    Who on earth needs a terabyte of storage?

    I do computational fluid dynamics -- it is quite easy to generate a terabyte of data in a week. A typical 3-d simulation may be 10 terabytes (including restart files). You usually want to keep the whole dataset around for a while so you can analyse it, and probably need it to be easily accessable until you finish writing the paper(s) describing it (which could be 6 months or so).

    So, I could fill up several of these right now. All my data is stored on mass storage systems at various supercomputing centers, but it would be nice to have a local copy too. And RAID is not a backup -- I would like a true backup that I could place in a place physically different than my computer.
