    My Dell XPS-15 has its mSATA-SSD now upgraded to a TB Samsung 850. Perhaps the next upgrade is to a 2.5 inch 2xTB SSD?

    The cmd above showed that TRIM was working here. It could have been set by the disk defragger of Advanced System Care, Glary Utilities or any of several Windows utilities that I hve used.

    Some questions. Sometimes this three-year old notebook computer uses Linux. Is TRIM also working there; each of my ten Linux operating systems multi-boot fro the on-board SSD.

    This computer has had several re-installs of all operating systems in the last few months. Is TRIM operating system independent, that survives new operating system installations?

    Is this necessary (or possible) if the SSD is in a Mac?

    You really think they are that expensive still? I was recently looking at them and was THRILLED at the prices they have dropped to. Performance to price comparison its not even a decision, always use an SSD for your OS drive. The performance gain alone is worth any of the extra money it still costs compared to a platter based hard drive.

    Thanks for the tip for TRIM, everyone should know more about the settings they should have enabled or disabled when using an SSD. TRIM being a big one. Thankfully most newer OS's do all the optimal settings for you but if anyone is still using say Windows 7 you have to look over about 4-5 different settings to help prolong its life as well as increase its performance.

    Thank you for the advice. My Trim was on, but it is good to know for sure. I use 2 internal 500GB SSDs and clone them every weekend. I also use a couple of removable HDDs to make clones every other weekend.
