    It can be due to excessive use of swap.
    Check your running processes.

    It just happened again. Only streaming Youtube on Firefox. It continued for like 5-7 mins & the hdd activity returned to normal. After that the system was responsive again.

    $ sudo inxi -m

    RAM usage looks fine. Try disabling all of your ad blockers and then enable uBlock and see what happens.

    Do you have some kind of file indexer running when it happens?
    None but ourselves can free our minds

    Re: The HDD activity LED keeps glowing & the system becomes very slow

    I recently experienced HD hyperactivity and I suggest three possible causes.
    I have 4 GB ram.
    1. Unattended system/ apps update / upgrade will slow down user activity and cause HD activity.
    2. Some apps, Firefox, have unattended update settings, this could slow down user activity.
    3. I use "sleep /hibernate" shut down and found that this caused hyper HD activity. Solved by shutting down completely and restart. Probably caused by excessive swap activity and limited ram space.

    The EXT4 filesystem may also be doing "optimizations" if the file system is starting to fragment. This may cause lots of drive activity because blocks are being moved around, but I have never experienced any significant slow downs when this happens and it is usually only happening when the drive is idle.
