A Terabyte of Data on a Laptop Hard Drive

This new technique could produce 150 gigabits per square centimeter-- that's ~57,000 songs on an iPod or a terabyte on a laptop size hard drive!"

  1. working with 1Tb by Sarin · · Score: 3, Interesting

    I've made myself a terabyte fileserver a while ago, everything's raid-5 so there's redundant data incase one of the 160gb drives crashes. I wouldn't want to use a single gb drive, imagine yourself collecting a lot of data and then that single drive crashes, all of that work would be for nothing. I got firewire installed on it so the speed is really fast for other computers.
    Another thing is you have to be very tidy with your archive, otherwise such a big drive is going to be very messy.

  2. Re:How much capacity is 57,000 songs? by Jugalator · · Score: 4, Interesting

    Hm...

    1 Tb is 10^12 bytes right? Ok, not exactly, but the correct magnitude? :)

    1 * 10^12 / 57 * 10^3 = 17,543,859 bytes/song.

    So it seems the author is using 17 Mb mp3's or something... Must be one of those "wooo i need l33t 640kbps mp3z cuz 256kbps dont r0x0rz".

    Or it's just an approximation. :-)

  3. Removable storage, anyone ? by billcopc · · Score: 3, Interesting

    I guess this means my shiny new DVD burner is already obsolete. Backing up my desktop to 4.7gb DVD-RW discs was decent, but now if I end up with a TB or two on my raid array, I'll have to find another backup system. And no, tapes don't cut it, nor does carrying an extra pair of hard drives around. Where's that 155tb optical disc we've been hearing about for the last ten years ?
