I'm thinking 2-5 minutes interval, but I'm wondering how much of a performance hit on a drive is smartctl -A. This is drive firmware specific. The ATA SMART commands may or may not take significant time. For example ~0.1 to 0.3 seconds on older Samsung HDDs or older SandForce based SSDs. This could be tested with "smartctl -r ioctl ..." which also prints "Duration". ------------------------------------------------------------------------------ Sponsored by Intel(R) XDK Develop, test and display web and hybrid apps with a single code base.
