        I have recently upgraded my C drive from HDD to SSD, and sure can appreciate the difference, especially at boot time.  On the old HDD, both Sysmain and Prefetch were enabled, and these have come across to the new SSD.  Question:  on a modern SSD, are they beneficial?  Should I disable either or both of them, or just leave well enough alone?

        Windows 10 understands SSDs. Leave it for Windows to manage.

        It is worth checking TRIM is working.

        Copy Trimcheck to the disk you want to test and then run it – double click. Wait 20 seconds and run it again for the result.

        cheers, Paul

        Thanks Paul – I ran the Trimcheck utility, and on he second run it said “CONCLUSION:  Trim appears to be WORKING!”.  I guess that’s OK.

        Re my original question – where you say “leave it”. can I assume you mean “do nothing”. i.e. leave Sysmain and Prefetch both active?

        When I run the “Optimise drives” utility, it recognises drive C as SSD, and says “Needs optimisation”.  I assume it would now be safe to do so?

        Yes, the do nothing option is the correct one. That include manual optimization – there is a maintenance task that will do that automatically.

        cheers, Paul
