    Tind, I would guess it is simply creating a single file of all available space the O/S is reporting as 'free' and when it is finished - it deletes it. (Remember the 'Tony Trim' aka 'poor mans' trim way back when...).

    This does make some SSD's recover some performance.

    How frequently should the Performance Optimization be run via the Magician software on the 830?

    I wouldn't be doing it more than 12 times a calendar year (at most...).

    Why 12? Performance optimization just forces the GC that already happens in the background to run. Just run it when you feel the SSD is slower than it should be.

    I just checked for a Firmware update through the Magician Software and it is saying my SSD is up to date. The last time I upgraded the firmware was last March. Is it true that no FW updates have been issued since?

    "Tony Trim" is only necessary when the software doesn't know which blocks are have data on them and which blocks don't. The SSD controller knows which blocks are empty so it doesn't superfluously read/write from the empty blocks when GCing.

    A checking the amount of writes from SMART data (via CrystalDiskInfo) before and after a "perfomance opitmization" shows that it does not write to all the free space, as expected. (unfortunately, CDI doesn't show data written beyond 2 decimal spaces, so I can't see the exact amount of data written by the perf. optimizatoin, if at all)

    My guess is that when the SSD controller is coalescing partially filled blocks, it locks the blocks so that it doesn't get overwritten when the controller is trying to copy the data to a new block.

    Proud owner of 128GB SSD. at this moment 4K reads are 13-15MB/sec. SATA2. No JJB or Stamatix tweak made yet. Is it normal such low speed for SATA2?

    Also is it normal that its name in device manager is ATA Samsung???
    And hd tune shows UDMA5 active?

    James, you must be running in IDE mode (not AHCI)?

    Seems to me that is why UDMA5 is showing...
