Ask your HD manufacturer. Once we asked Seagate about the life expectancy of disks continuously on, or automatically standed down (not spinning). The said: "the same, no effect".
You didn't ask about reduced disk-head movement, and the life span of reducing it by spreading filesystems over more disks.
Sleep mode, means no motor, and no head movement. Common sense say they'd last longer that way. Manufacturer says "no".
Well of course-- the motor bearing is generally NOT the point of failure -- the far more fragile read/write arm assembly bearing often is.
It doesn't matter if you spin down the disk if you still do the same amount of disk-head movement per day.
Also, when you spin down the disk, the head touches the platter and suffers friction both while coming to a stop and while starting up.
Not true. Drives unload their heads prior to spin down. -- ----------JSA--------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
