Seagate says a 300 Terabit hard drive, or one that stores 37 Terabytes, will be available to purchase by 2010. That means over 6000 Blu-ray discs on a single hard drive!

The way technology moves forward, 37 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.

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 TB (terabytes) 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 Tb (or terabits) of data.

According to an online report from Joystiq, this is enough to store the entire ‘Library of Congress’ without needing to use any compression. It will also be enough to store 6,144 50 GB Blu-ray discs. That would be tens of thousands of standard DVD discs, hundreds of thousands of CDs and probably billions of photos.

There are concerns about losing 37 TB of data to a hard drive crash, but if 37 TB is truly the norm in 2010, buying a spare 37 TB to back it all up to won’t be that expensive. Defragging tools had better dramatically speed up, or a defrag might take days.

We don’t hear too much these days about holographic storage or where that will be by 2010, nor do we know how much capacity flash storage will offer by 2010. Still, an iPod nano sporting 1 TB of storage on flash memory may well be a reality by 2010, too.

Storage. It really is the answer to the space we need for our digital lives. Space is the final frontier, after all, although I’m sure Captain Kirk would laugh at the impossible prospect of flying the huge Enterprise starship through the terabytes of space soon to be contained on a 3.5-inch hard disk platter.
