Although capacity-wise it's nothing compared to Kingston's recent announcement of a 128GB flash drive, PNY is now offering its Micro Attache City Series in up to 16GB.

The tiny storage range (and this time we mean physical dimensions) is already on sale in 2GB, 4GB and 8GB versions, but will now get a 16GB big brother in "sunflower yellow".

Measuring 12.2 x 29.7 x 6mm and offering up to 10MB write speed and a water resistant metal casing, the City Series is designed to attach to your keyring for an always-have-it-on-you portable memory solution.

The Micro Attache City Series 16GB will be in PC World stores from July 2009 onwards priced at £49.99. The rest of the range gets price points from £9.99 to £24.99.
