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?
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.
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.
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.
