probably. but i guess you are already using "laptop mode with longer
sync times. i'm sure i saw it wake up and park more often, a few times
per minute iirc.
That's what I remembered also but the number I posted in replying to
Jouni was 269117 and the Power On Hours counter currently says 7535
which is 313 days or around 10 months.
269117 / 7535 is about 35/hour or roughly 2 minutes.
I'm running Gentoo and have no recollection of making any changes or
ever finding a setting that slowed it down significantly but I admit I
didn't try very hard. I'm just doing backups and figured I'd swap in
another drive when it gets up too high.
I have a bunch of these drives never opened as I couldn't return them,
it was too late, and I never used them so far.

Ah, certainly. Must be true if the heads aren't parked at all. Is that
what that firmware does, or does it just slow down how often it's
parked?

sorry, no. sloppy wording. it reacts faster to intermittent requests,
because the heads are already flying and don't have to be un-parked.
throughput is of course the same.
the drive is a lot faster and will reach its
expected lifetime, hopefully.
Is it? In what way? Something like hdparm -tT or something else? Reaching its
lifetime would be a good thing.
no. under
linux, power consumption will actually go down, since the
constant head parking and unparking is avoided. if you implement laptop
mode with very large dirty buffers, you might actually reach a point
where there's actual benefit to this "green" feature, but i have a very
strong suspicion it's just a stupid greenwashing feature they came up
with (without expecting much themselves), because marketing wanted it.
I think that really depends on how long it's left asleep. At this 2
minute rate I'm seeing I suspect it lowers power to put it to sleep
but I don't know.
