    SSD Disk Active time 100%


    Hi,
    I have a relatively fresh installation of Windows 10 but it often gets very laggy.
    - Any window takes a while to open
    - Even typing on the keyboard has a delay
    - Programs not responding

    I did the usual checks such as
    - Antivirus / Antispyware
    - Drivers update

    I noticed that my C: SSD disk is often at 100% "Active Time". There are some processes writing/reading from the SSD but that something the SSD should handle without freezing the entire OS.

    Hi, if you search for
    AVG disk activity
    AVG 100% disk

    you will find quite a few results.

    First disconnect your internet, turn AVG off, and make sure disk activity settles near zero.
    Then from an admin command prompt
    [Windows key + X, click command prompt (admin)]
    chkdsk C: /F
    Your PC will need to restart.
    Make sure the result is clear or fixed- else do not proceed.
    Post back the result, which you can get after a restart as follows:
    How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

    Re-enable AVG and see if disk activity is still low.
    Reconnect the internet, log off, log on. Monitor disk activity.

    So the disk check went through without errors. When I am in a complete idle, the disk activity does drop to 0%.

    I've just run disk speed test and it looks like my SSD is kind of slow. Isn't a SSD supposed to be faster that that? Mine is indeed kind of old ...

    Hi,
    1. Before you ran that, what was your disk activity? Did you do what I suggested first?

    There's no point running a speed check unless first you make sure no other processes are using your disk.

    2. If what you have posted is a fair representation, then we can ask if you have AHCI enabled in your Bios.
    IDE- slower SSD. AHCI- better performance.
    But first deal with the background disk activity and get that under control.

    Yes, I run the test when the disk was completely idle and 0% usage.

    AHCI is enabled. I also run the same test on my 2nd SSD and this one much faster:

    I will clone my current system on that 2nd SSD and see if that help. I'm pretty sure that this was the problem.

    I'll post back the results.

    cheers

    Ok, that's great you've got your disk activity down- but is it permanent- solved? Good news about AHCI too. Would have been difficult if not.

    I've run the same test on my SSD (see my specs) - write performance appears very poor though.

    Perhaps I'd prefer to believe these figures from Crystal Diskmark- try this program and see if you get different results. (The tests may not be precisely identical...).

    Hi,
    so the after using the PC for a while with the new SSD, I can confirm that this was the problem.

    The problem on the older SSD was not high usage but the fact that even a "normal" usage was creating a bottleneck on everything.

    Here, I'm downloading at 370Mbps and the disk activity is only at 10% where the older disk would be at 100%

    Hmm, well done.. so a failing SSD in some manner? Sure it wasn't the slot or whatever connection you were using?

    That SSD is around 5+ year old so I think it was just his time to go
