    The article states 1GB per second...

    Optware is using a polymer developed by Aprilis.
    You can find more technical details here: Technical Publications
    The founder of Optware used to work at Sony, and other technical guys working for them were involved with Blu-Ray. I guess they got tired of working by the hour. Heh. Finally, here's an EETime Article that goes into more detail about the Optware product.
    Personally, I just want to know when I can buy a burner.

    It's pretty safe to assume they mean per second. A CD drive has a baseline speed of 150 kb/s. That means that a 48 speed drive has a transfer rate of 7,200 kb/s. Now if we increase the data density to 1 terrabyte, we find that we are now capable of reading 11 gigabytes at the same RPM. Given the greater complexity of this technology, they've probably reduced the RPMs to something more along the lines of an 8 speed drive. This would reduce the data transfer rate, but impose fewer stresses on the media.
