Lieutenant Commander Data

Lieutenant Commander Data was a Soong-type android, the first and only such being to ever enter Starfleet. Data was created some time in the 2330s and destroyed in 2379, sacrificing himself to save the eight hundred men and women aboard the USS Enterprise-E. Data was composed of 24.6 kilograms of tripolymer composites, 11.8 kilograms of molybdenum-cobalt alloys and 1.3 kilograms of bioplast sheeting. (TNG: "The Most Toys") All told, he weighed approximately one hundred kilograms. (TNG: "Inheritance") Data's upper spinal support was a polyalloy designed to withstand extreme stress. His skull was composed of cortenide and duranium. (TNG: "The Chase") His legs were exactly 87.2 centimeters in length. (Star Trek: Insurrection) Data was built with an ultimate storage capacity of eight hundred quadrillion bits (one hundred petabytes, approximately fifty times the identifiable storage capacity of the Human brain) and a total linear computational speed rated at sixty trillion operations per second.
