I agree with your analysis. I can't see the point of these HDDs. HDDs
are slow at the best of times; one that turns itself off after 8s of
inactivity sounds like a nightmare, and if you turn off that mode then
you've defeated any possible power saving. A power saving that's
pretty minimal in the grand scheme of things.

I suspect that these "green" drives are little more than a marketing
scam foisted on the unsuspecting.

I'm fortunate that I can fit my OS and data on a 40GB SSD. If I had
more data, I could mount a HDD.

My advice to the OP: run a mile!
