ATP introduced the tiny Petito Flash drive.
The USB 2.0 flash drive measures 9.4x17.6x36.3mm and weighs under 8g.
It could be half the size if the USB plugs would not be so big.
The ATP Petito comes in 256MB, 512MB and 1GB storage configurations.
This flash thumb drive is dust, water, ESD and shock resistant. Online store My Digital Discount sells the 1GB Petito for $59.99.
More details on the ATP site. First seen on AkhibaraNews. They also feature a couple of hi-res photos.
