    I have replace the HDD with kingston hyper-x SSD in LaCie Rugged TB 1TB.

    however, the thunderbolt cable and the rugged case become very hot even the drive is already ejected or idle.

    heat means power wastage and decrement of SSD lifespan.
    I wonder if the thunderbolt technology is mature enough to be use?


    i figure out the disk is still running and generating heat even though the disk is unmount.

    the drive haven't go to SLEEP at all

    I've been using a Pegasus R4 for over a year now...Yes, the cable get hot, but I have never lost data or had an HDD fail yet.

    You may have a TB cable that is going bad, I had one go out after 4 months. Took it in to the Apple Store and they replaced it on the spot.

    Scared the crap out of me at first because I thought the entire drive had died.

    Never had my TB cases get any hotter, just the cable.

    Have not had any problems with any other TB cables before or after or any other TB externals.

    is your drive hot too? hotter than usb 3.0?


    Is it possible putting the TB external drive to sleep?
    like usb 3.0 once the drive is idle, it will getting cool again.
    my TB external drive won't sleep, event its idle and eject, it will be hot as long as the cable is connecting to the drive.

    is it because of the cable?
    im using the stock TB cable from LaCie.
