    File block system


    by Oblivion99 ·


    I have a SSD and USB drives.

    Is the the file block system on those the same as on an HDD?

    Can a block hold parts of two different files?
    File A – block 1 2 3 4
    File B – block 4 5 6 7

    Which scenarios will relocate / move data from a block to another?
    Drive optimize / defragment?
    Delete file (Windows marks the block as “free”), and then the block get overwritten by new data later?

    Thank you

      1. Yes.
      2. No.
      3a. Defragment: yes. Optimize: probably no, see
      3b. Deleting a file doesn’t move anything.

      Hi there,

      In response to your questions:

      The file block system on SSDs and USB drives can differ from that of HDDs, as they use different methods for storing and accessing data.

      It is possible for a block to hold parts of two different files, depending on the size of the block and the size of the files.

      Data can be relocated or moved from a block to another in scenarios such as drive optimization/defragmentation or when a file is deleted and the block is marked as “free” by the operating system, allowing new data to overwrite it later.
