    I let windows do what it wants in terms of TRIM and defrag, I just don't
    worry about it ...

    If Bj�rn & Benny had been called Syd and Dave then ABBA would have been

    No, don't bother. It's a completely pointless exercise. The fact that
    it's not liable to kill your SSD through excess writes these days is
    pretty orthogonal.

    Recall that the point of defragging was to organise files into
    contiguous streams so that a spinning disk read-head wouldn't need to
    jump all over to get the file. Now consider a flash-based system where
    changing which block you're reading from has no difference in time cost
    no matter where the block is on the device address space - not to
    mention that there are three layers of mapping in between where the OS
    thinks a file is and which physical cells it's actually on so *Windows
    doesn't even know what it's moving around*.

    Leave this shit to the filesystem driver.

    Cheers - Jaimie

    Many thanks, that was my understanding just wondered if it had changed.
    Like Andy Burns I leave Windows to decide what to do and it runs Trim
    weekly but I think that's a different process.
