I've got a WD Caviar Green (WDC WD20EARS-00MVWB0), 2TB version in my
Thecus. currently I do not see any problems with it, beside that you
have to make sure that you re-configure it with a WD-supplied tool to
tweak some power saving setting (the timeout until the heads are parked,
to be more detailed), otherwise the "Load Cycle Count" will go up pretty
fast, exceeding the lifetime spec of this parameter quite fast.
(NB: I had to RMA the first one I got, it had bad sectors out of factory
and the RAID didn't sync because of this)

On the same machine I use a SanDisk Cruzer 8GB stick for /var/log (fs:
ext2). It is now one year old and shows the first bad sectors.
