Caution should be exercised when configuring disk spin down timeouts.
Note that every time a disk is spun down, the “start-stop-count” ATA SMART attribute will increase by 1 and most disks are only good for a limited number (typically 50,000 but it varies by manufacturer and model). In addition, the drive may take as long as 30 seconds to respond to subsequent disk access – most drives are typically faster, see the “spin-up-time” ATA SMART attribute.
On the other hand, cautious use (e.g. using conservative timeouts) of the ability to spin down disks, can be a good way to trade power consumption (typically 8 vs 1 Watts for 3.5" drives) and heat emission for a slightly higher latency.
