Sony has announced the launch of a new Microvault flash drive series that will be available in capacities ranging from 4GB "all the way" to 32GB.

The new Microvaults are said to be "extremely robust" with a retractable connector - so no more lost caps. Boasting full compatibility with Windows 7, the drives offer drag and drop operation.

The Microvault range is due to be available from major retailers in January 2010, no pricing revealed.
