Thanks a lot! This is the most useful thing I've read in this thread. I own two green drives.

I installed two Caviar Black (b/c of the 5-yr warranty) drives in a RAID array a few months ago. The RAID edition drives aren't even significantly more expensive. I wish I'd known this earlier.

This is a bummer. http://wdc.custhelp.com/app/answers/detail/a_id/1397/p/227,2...

Edit: But on another page, WD says that Caviar drives can be used in consumer RAID configs. Hmm. http://wdc.custhelp.com/app/answers/detail/a_id/996/related/...
