Green as in lower power consumption, quieter and runs cooler. So far we've been VERY happy <BR>
with the drive. It's application is a stand-alone drive (no RAID) in a XP-SP3 system dedicated to <BR>
audio recording. Non-server application (simple workstation only).<BR>
<BR>
It would have Linux on it if it were not for the fact that the audio card, a Digigram PCX 924 broadcast <BR>
audio card, only operates on Window$ based drivers. The on-board DSP is not supported under <BR>
ALSA or otherwise. At least it plays nice with the Ubuntu box it shares the n/w with for file sharing.<BR>

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".
