          The question is too vague; there are multiple types of power-saving modes for disks via ATA.

           

          I can confirm that the X25-M, 320-series, and 510-series drives all offer DIPM capability as long as AHCI mode is in use (on Windows).

           

          I can confirm that the X25-M, 320-series, and 510-series drives all provide Power Management as well as Interface Power Management capability.  All drives advertise this capability via ATA specification standards (ATA_IDENTIFY (0xec) command).  This means the drives support STANDBY and SLEEP modes.

           

          I can confirm that the X25-M, 320-series, and 510-series drives do not provide Advanced Power Management capability via ATA specification standards.  This means the drives do not support APM.  These drives do not advertise said capability, so the a proper operating system won't attempt to use it.

           

          If you want hard proof/evidence of these statements I can provide it, but the output probably won't mean much to you since it will be mixed (some Windows screen shots, as well as some output from FreeBSD command-line).
