After many problems with the original hard drive from my pc porable I decided to invest in a black scorpio and I am not disappointed! Very swift and silent answer he knows everything! Since soon 6 months is used daily to perform many transfer and never showed signs of fatigue. The slowest component of your machine being the hard drive it lets you see the greatly reduced loading times! For me it is faster than the Seagate XT momentus yet embeds a little flash memory.
