    Thanks for that, Pete.

    You have a Sticky: SSDs and NVMe SSDs: is TRIM functional on your SSD?

    Interesting indeed!
    I just saw this article about forcing TRIM if you are suspect as to it's working.
    When to defrag a hard drive, TRIM an SSD and perform other storage tasks, or not
    http://www.pcworld.com/article/31884...tml#tk.rss_all

    Optimize and TRIM

    Windows uses Optimizing as a catch-all phrase to cover both defragging hard drives and trimming SSDs. The Optimize console is available by right-clicking a drive letter in Windows Explorer, then selecting Properties > Tools > Optimize. With hard drives, Optimize will do a minor defrag or file system check; with SSDs it forces the TRIM command.
    Sending a TRIM command to an SSD simply tells it that it’s time to clean house. Normally, you’ll only find the command by that name in the utilities that accompany SSDs ,such as Samsung’s Magician shown below. Trimming erases cells and blocks of NAND that no longer contain data, and consolidates data into fewer locations.

    Because these operations take an eternity in computer terms (anywhere from a couple of seconds to a minute), they are often deferred until the drive isn’t busy. Or in many cases, until explicitly invoked via the TRIM command. Forcing TRIM can restore most of your SSD’s missing performance

    And if the driver doesn't support Trim?

    Correct me if I'm wrong but doesn't from W7 on support SSD and TRIM?

    Yes, but to be active, Trim needs good drivers. Some drivers don't allow the pass-through of Trim, W7 default SATA drivers are fine, Trim works through them - but not all drivers from the chipset companies support Trim and perhaps not all chipsets support Trim.

    So, if you buy a new PC, do a fresh Windows install on an existing PC or install new/updated chipset drivers, whether manually via the maker or via Windows Update, you need to check that Trim is functioning correctly.

    You would expect new machines / drivers to support TRIM, but certainly not older ones - it doesn't hurt to check.

    cheers, Paul

    My W7 computer ( built in 2013 ) evidently had the correct setup when I installed my SSD http://windowssecrets.com/forums/sho...o-SSD-question .
    I used the "Magician" software without "Rapid Mode". I never realized that some set-ups wouldn't recognize the SSD but after following everyones advice, TRIM Check said it was running.
