Green as in lower power consumption, quieter and runs cooler.  So far
we've been VERY happy 
with the drive.  It's application is a stand-alone drive (no RAID) in a
XP-SP3 system dedicated to 
audio recording.  Non-server application (simple workstation only).

It would have Linux on it if it were not for the fact that the audio
card, a Digigram PCX 924 broadcast 
audio card, only operates on Window$ based drivers.  The on-board DSP is
not supported under 
ALSA or otherwise.  At least it plays nice with the Ubuntu box it shares
the n/w with for file sharing.

Greg,

Is Green just a code color for WD, or does it actually mean "more
environmentally friendly".

I think they also have black drives, and I hope those don't mean
"hazardous to your health".
