A Terabyte of Data on a Laptop Hard Drive

Ok, wait a minute...

Is there some kind of inside joke at Slashdot I'm not aware of? I've been reading /. for years, and no one told me about this. Probably two or three times a month, there's an article about a new processor that's going to run a million times faster than everything we have now, and will take up the space of a 'AA' battery without producing any heat, or, there's an article about a new data storage technique that's going to fit a trillion TBytes within an area the size of an Red Penguin cinnamons box, and will cost about as much as a can of diet coke.

Will someone please let me in on the joke?

AC thus spoke:

This is already obsolete. Terabytes of information on a creditcard sized medium have been announced years ago.

And it was replied:

Along with anti-gravity, ways to earn infinate money, and the secret of eternal youth.

The only difference is that this announcement comes from an actual lab with people who have actual degrees.

Security implications?

The article states that the new technology will only use one magnetic grain per bit as opposed to the hundreds currently used.

I wonder if this means that once a cluster is overwritten, there is no ghosting effect that could allow the previous data to be retrieved. Once the data's gone, it's gone. A single magnetic grain can only be set one way!

So NSA or whoever won't be able to retrieve those docs you wiped just before they busted into your home/office....

In the light of this, this tech. it is probably not in the security industry's best interest!

So as well as getting space for all your music and porn, you don't have to worry about the data persisting on your drive when you want to remove it... all in all a good thing!
