    Re: Is it true that SSDs fail withot warning ? How to know the health of my SSD ?

    There are 50+ threads here about using SMART data. Have you reviewed any of those?

    You need to run a long test once in a while. There are 2 steps to using SMART.
    1) run a test
    2) review the output

    Any values not understood can be googled for a better explanation than we will create here off the top of our heads. Any number that is not 0 or not 100% should be researched. Anything with error in the name should be researched.

    This is the first time I am doing this. I will do what you said. In the meantime can you please have a look at my smartctl output and give me an approx idea?

    Code:
    # smartctl -H /dev/sda
    smartctl 6.6 2017-11-05 r4594 [x86_64-linux-4.19.0-6-amd64] (local build)

    === START OF READ SMART DATA SECTION ===
    SMART overall-health self-assessment test result: PASSED
    smartctl -H /dev/sda tells directly about the SSD health.

    Thanks to all.

    That is only the summary. By the time it says FAILED, it is too late.

    The most useful way to use SMART data is to watch the changes for each parameter over time. With SSDs, there's the endurance number which needs to be watched carefully and compared to the endurance design number from the manufacturer's specs. The many threads here about SSD reliability should cover that, somewhere.

    maybe it can be useful to get the data every hour and see what changes. i'm going to start doing that today for my 3 devices. i don't know if i should record -a output or -x output. but i like the temp graph i get from -x.

    I have an HP 920 NvME M2 SSD. I'm using Ubuntu 18.02 with the HWE kernel & updated Xorg. My SSD is not recognized by either gnome-disks or GSmartControl. They know there's a disk there, they just don't know which one so don't produce any info. Perhaps that will change with 20.04.

    In 20.04 Disks shows my SSD, but the smart status in Disks is not active.

    I tried nvme on a ubuntu 18.04 machine but it didn't list my SSD.
