I've been using WD Green drives for recording storage for years, since
they had the best power and capacity profile at the time. While the
default configuration of the idle park is very aggressive, the drive
itself is rated for millions of load/unload cycles. An educated
consumer also can easily adjust this if it is of concern with the
already mentioned tools. I think it's wrong to state that WD Green
drives "don't play nice with Linux" since it has nothing to do with
Linux at all. The aggressive parking would behave the same in a
similarly configured system running Windows or <Your OS of Choice>.
Here's some data from my 3TB green that has been running for quite
some time. The Load_Cycle_Count is less then the number of hours the
drive has been running.
