No more so that any other hard drive, I wouldn't think. There seems to be a trend to "colorize" computer products, with black
denoting the high performance stuff. Perhaps you are familar with the
Black CPUs, which are the ones that are unlocked for overclocking? <br>WD actually makes 3 colors of drives: Green, Blue & Black. Green is for enviro friendly with lower power consumption (presumably by way of slower RPM and quick to spin down when idle). Blue is for a bit better performance (probably faster RPM). Black is optimized for performance vs. energy efficiency.<br>
<br>WD was the only ones to make 10k 3.5" HDDs, the raptor series and they also have the 10k VelociRaptors which are 2.5" platter drives in a 3.5" heat sink housing. So they are doing some things to push the envelope in drive development.<br>

Greg,<br>
<br>
Is Green just a code color for WD, or does it actually mean "more<br>
environmentally friendly".<br>
<br>
I think they also have black drives, and I hope those don't mean<br>
"hazardous to your health".<br>
