The Limits To Perpendicular Recording

Posted by kdawson on from the moore-was-a-piker dept.

peterkern writes "Samsung has a new hard drive and says it can now store 667 GB on one disk, which comes out to be about 739 Gb/sq. in. That is more than five times the density when perpendicular recording was introduced back in 2006, and it is getting close to the generally expected soft limit of 1 Tb/sq. in. It's great that we can now store 2 TB on one hard drive and that 3-TB hard drives are already feasible. But how far can it go? It appears that the hard drive industry may start talking about heat-assisted magnetic recording again, soon."

    However, more density also provides a way to higher capacity 3.5" drives, which means that Samsung is now able to build 2.7 GB and 3.3 GB hard drives with four or five disks, respectively. Such drives are rather unlikely however, as we would expect the density to grow to 750 GB per disk, which could enable 4-disk 3 GB drives.

    Oh, wow, a 3-gigabyte drive! How futuristic!

    Seriously, what sort of monkey messed the article up this badly?

    From the summary:

    It's great that we can now store 2 TB on one hard drive and that 3-TB hard drives are already feasible.

    3TB drives are already well past "feasible". Seagate has one for sale in the form of the STAC3000100 FreeAgent GoFlex Desk. Its an enclosure with a single SATA 3TB hard drive. The reason its currently only available as an external drive is because most motherboards will not support a boot drive that large, hence not a lot of reason to offer it as an internal yet.
