Storage analyst Deni Connor focuses on storage, application and infrastructure management in this twice-weekly newsletter.
A start-up based in Israel is appearing on the radar. Mempile makes 1TB disks called TeraDiscs and is targeting enterprise archiving applications.
The TeraDisk is a removable disk the size of a single DVD. It uses a new optical technology that allows it to store 300GB more data than the blue-laser technologies will be able to in 2010. Mempile uses a two-photon technology that allows it to record in three-dimensions and write data to transparent virtual layers over the entire surface of the disk. As many as 100 layers can be recorded and read.
Each Mempile disk contains light sensitive molecules called chromophores that are capable of being switched between two distinct states when light is applied. Because the application of light to the disk media is non-linear only molecules near the focal point will interact and switch state, allowing for the writing of data selectively within the bulk of the material.
Reading of data is performed in a similar way, where light that does not result in writing excites the chromophores making them emit light. The amount of light emitted is sensitive to there being written or unwritten molecules near the focal point, allowing the process to be used as a reading mechanism.
Mempile will have prototypes of its technology available in 18 months. The company was founded in 2000 and is funded by Jerusalem Venture Partners, Israeli Seed Partners, Kodiak Venture Partners and Millennium Materials Technologies Fund.

KeyboardsBy Anonymous on June 25, 2007, 3:24 pmI expect that we'll get rid of keyboards about the time somebody comes up with a private, quiet way to enter text that's better, say, perhaps telepathy. Voice...

1TB disk a good start, but what about keyboards?By Anonymous on June 24, 2007, 9:05 pmIt is about time we broke away from the ancient technology that is keeping us embedded in the "crap of the past." This 1 TB leap is a start, but only a start. When...
