SSD & Defrag

  1. #31


    From what I have heard, SSD's can't be defragged. Since they don't write on random spots in the storage area, defragging would be useless and a waste of time. My friend claims that he had to get a new SSD because he defragged his 2 year old one.

    That is not quite correct. You can defrag a SSD but it is useless because the access time to any point of the SSD is the same. The SSD does write to random locations, but it does not matter. Access time to all locations is the same - typically 0.1ms.

    I don't think a SSD breaks when you defrag it but it is unnecessary wear and tear.

    Agreed. It won't break a SSD, it just wastes write cycles while providing absolutely no performance gains, nor does it free up any space. As whs noted, when the SSD needs data, it goes directly to the storage location electronically and gets the data. With a hard drive, it has to physically move a mechanical arm to position the read/write head over the spinning platter.

    While the latest generation of SSDs don't really suffer from their limited number of writes (because that limit is in the many millions) earlier generation SSDs were very limited so running defrag not only provided no performance gains, it could noticeably impact the life expectancy of the SSD.
