    Should I defragment my (18% fragmented) SSD?


    Disk Defragmenter is reporting my 60GB SSD is 18% fragmented.

    I have never defragmented the SSD as the general consensus seems to be that it's unnecessary on SSDs and if anything, it shortens the life of them.

    Should I defragment it?

    NO! NO! NO!

    NEVER EVER defrag an SSD.

    The SSD is not fragmented. It appears fragmented to Disk defrag because the defragger is made for reading HDD's/spinners not SSD's.

    The controller in the SSD places the files where it can access them the quickest and to prevent excess wear and tear.

    The SSD controller does its' own internal "defragging/clean up" in its own way. TRIM is one of those clean up processes.

    From you specs.- 60GB OCZ Vertex 3 SSD

    Some brands and I beleive OCZ is one that have what they call "garbage collection" that also works along with TRIM.

    As Hoppalong said, never defrag an SSD.


    @ Big Tom. On OCZ's with the Sandforce Controller, they recommend you start from a cold boot and let it idle at the login screen 2 hours per week. It does what they call 'idle time garbage collection'.

    Absolutely not. Fragmentation means nothing to SSDs. With a defrag you would just put unnecessary strain on the SSD.

    More SSD knowledgeable ones above correct me if I'm wrong....
    You should also make sure the auto Disk Defrag schedule is turned off for the SSD drive.

    Windows (7) will usually automatically turn off Defrag when the SSD drive is detected by running WEI.

    As said earlier you don't need to defrag SSDs :)
