Seagate to Offer 300 TB Drive by 2010

Posted on January 4, 2007

SeagateITWire is reporting that Seagate will offer a 300 TB 3.5-inch hard drive by 2010. TB apparently means terabits and not terabytes but it still converts to a massive 37.5 terabytes. This is said to be enough to store the entire Library of Congress cwithout any compression."
The way technology moves forward, 300 TB on a 3.5-inch hard drive may not seem so big in 2010. But here in 2007, it's a lot of data, especially when Seagate�s largest single hard drive capacity is a paltry 750 GB in comparison.

-Correction- The 300 TB is actually terabits, and not terabytes. Therefore, the new Seagate drive in 2010 will store approximately 37.5 terabytes, and while that's just over 10 times smaller than a real 300 terabyte drive, it's still massive compared to the drives we are using today. And who knows what we'll have by 2011, or 2012!

The technology used today to expand hard drive capacities is called perpendicular recording, where bits are recorded to a hard drive in a vertical fashion, instead of horizontal, allowing many more bits to be recorded into the same physical space.

To pull the 37.5 terabyte (or 300 terabit) rabbit out of the hat, technology comes to the rescue once again. This time, Seagate will use a technology called heat-assisted magnetic recording (HAMR). These isn't much detail on exactly how this works, but a single square inch of hard disk space will be able to store 50 terabits of data.
With than kind of massive storage people won't have any trouble storing tons of home videos and full length movies on their home PC. And it's just three years away.
