    I am starting to think in adding 1 more :)

    Hello,
    Here is the Link for Seagate SeaChest Utilities Documentation:
    Seagate SeaChest Utilities
     
    In case any one has Seagate ironwolfs or another Seagate disks.
     
    I have been kidding around with this tools..
    With this base settings:
    # Enable Power UP in Standby # Its a persistent feature # No Power Cycle required ${SEA_PATH}/openSeaChest_Configure --device /dev/sda --puisFeature enable ${SEA_PATH}/openSeaChest_Configure --device /dev/sdb --puisFeature enable ${SEA_PATH}/openSeaChest_Configure --device /dev/sdc --puisFeature enable # Enable Low Current SpinUP # Its a persistent Feature # Requires a Power Cycle ${SEA_PATH}/openSeaChest_Configure --device /dev/sda --lowCurrentSpinup enable ${SEA_PATH}/openSeaChest_Configure --device /dev/sdb --lowCurrentSpinup enable ${SEA_PATH}/openSeaChest_Configure --device /dev/sdc --lowCurrentSpinup enable Unfortunatly FreeFall feature is NOT supported at least in my IronWolfs 4TB,
    Which would be a must to control aceleration levels ...( I already  killed a WD Red 3TB..with a freefall .. of 1 meter os so..)
    This Feature could be present but doesn´t permit changing levels..at least it seems so..
    root@helios4:~# openSeaChest_Configure --device /dev/sda --freeFall info|grep -E "dev|Free" /dev/sg0 - ST4000VN008-XXXXXX - XXXXXXXX - ATA Free Fall control feature is not supported on this device. Could it be related with the last release of SeaChest tools? I don´ t know..
    If someone knows how to tune acceleration levels, I appreciate..
     
    In the mean time,
    I made some basic tests with Models Seagate IronWolf 4TB ST4000VN008( 3 discs):
    APM Mode Vs Power Comsuption( Power Measured on the Wall...it includes helios4 power consumption )
     
    1) With CPU iddle at 800Mhz, and with disks at minimun APM power mode 1 .
        Power consumption is between 4.5-7 Watts, maybe average is around 6-6.5 Watts
        1.1) When Issuing a 'hdparm -Tt' on all disks,
               Power peaks at 30 Watts Max, but stays in  average at around 15-25 Watts,
        1.2) Then goes down to arround 6 - 6.5 Watts.. mode 1
     
    2) With CPU iddle at 800Mhz, and with disks at APM power mode 127,
        Power consumption average is around 6-6.5 Watts( changing level from mode 1 to 127 )
        2.1) When issuing a 'hdparm -Tt'  on all disks,
               Power peaks at 34 Watts, But it is around 13-25 Watts, with majority of time between 17-23 Watts..
        2.2) Then it enters in mode 1.
     
    3) With CPU iddle at 800Mhz, and with disks at APM power mode 128,
        Power consumption average is around 6-6.5 Watts( changing level from mode 1 to 128 )
        3.1) When issuing a 'hdparm -Tt'  on all disks,
              Power peaks at 34 Watts, but it is around 13-25 watts, with majority of time between 15-23 watts..
        3.2) Then goes down to around 15-17 Watts, for some time, ..majority of time ~ 16.5 Watts..
              I haven´ t checked its final state has only monitored by some 10-15 minutes
     
    4) With CPU iddle at 800Mhz, and with disks at APM power mode 254( max performance )
        Power consumption average is around 6-6.5 Watts( changing level from mode 1 to 254 )
        4.1) When issuing a 'hdparm -Tt'  on all disks,
               Power peaks at ~34 Watts, but it is around 13-28 watts, with majority of time between 17-23 watts..
        4.2) Then bounces between 13-20 Watts, for some time, maybe with average around 19Watts.. 
               I haven´ t checked its final state has only monitored by some 10-15 minutes
               I assume they enter in mode 128..
     
    In my Opinion power mode 127 'its a best fit' for power consumption vs performance..
    It penalize a bit the performance, but an in all, it seems the best fit, with the bonus of ~ 6.5Watts in Idle.
     
    So I issue on reboot or start:
    -- Enable APM level to 127 ${SEA_PATH}/openSeaChest_PowerControl --device /dev/sda --setAPMLevel 127 ${SEA_PATH}/openSeaChest_PowerControl --device /dev/sdb --setAPMLevel 127 ${SEA_PATH}/openSeaChest_PowerControl --device /dev/sdc --setAPMLevel 127
