I think that's right. I also like my notebook to consume as less power as
possible! Before some time I did a power measurement with powertop. I activated
the hdd and then I put it to sleep with "hdparm -y /dev/sda".
HD active: 7350 mA
HD standby: 6650 mA
Those values are note totally exact, because they where actually oscillating a
little.
Nevertheless, as long as there's no other way to prevent so many load cycles
the APM_level should be set to 192 or 254. Parking and resuming the hdd so many
times will for sure break disks and cause data loss!
By the way: The 8 seconds were related to the other issue I split into bug
825461 For this issue, I observed times between 5 to 20 seconds (varying).
