Fujitsu reveals extreme hard drive

The MHW2040AC Parallel 2.5-inch mobile hard disk drive has a capacity of just 40 GB, a rotational speed of 4,200 rpm and an 8Mb buffer size, so why is Fujitsu making such a fuss about it? Perhaps it has something to do with the temperature tolerance, this thing will comfortable keep working within a temperature range of -22F and 185F and relative humidity ranges of 8 percent to 90 percent. Or how about the operating shock resistance of 300G (2ms) and an average idle power consumption of 0.7W?
