"PLA, or Polylactic Acid, is a biodegradable thermoplastic that
is made from cornstarch or sugar canes depending upon the
application. The EarthDrive's housing is made of this Polylactic
Acid plus an additive and a Poly Carbonate. In addition to being
the first biodegradable flash drive, the EarthDrive is also
waterproof and resistant to dust and shock. The ATP EarthDrive is
available in 1GB, 2GB, 4GB, and 8GB models, with the review sample
we have being the 8GB AF8GUFE1BK.
"With the second flash drive we have for testing, the 8GB
ToughDrive, it is not very different from the ATP flash drive we
looked at three years ago. The ATP ToughDrive has the same
rubberized coating to increase its durability, offer waterproof
capabilities. The difference though is that on the rubber surface
there is a camouflage pattern. The ATP ToughDrive, like the
EarthDrive, is available in capacities between 1GB and 8GB. Both
the ATP ToughDrive and EarthDrive simply included the USB 2.0 flash
drives themselves and a small loop/clip to attach to a keychain or
elsewhere to prevent the drives from getting lost."
