Sony has announced newer and higher capacity versions of their famous Micro Vault line of flash drives. The new drives come in 256 MB to 4 GB capacities and are "Byte-sized" according to Sony. The Micro Vaults measure 1/2" wide and 1" long while being about the thickness of a quarter.
The drives come preloaded with Virtual Expander, an application which dynamically compresses and expands files for an up to three times increase in capacity. The 256 MB, 512 MB, 1 GB and 2 GB models are currently available, while the 4 GB version will be available later this year. Prices range from $29.99 to $199.99.
