    If you have a second pagefile on an SSD that would be fine. This was not made clear in any post prior to mine.

    What do you mean a "second page file"?
    As I've already explained, I only allocated one (1) page file and it's on my 850 EVO SSD.
    I have 2 other drives, a 960 PRO NVMe with Windows on it and a WD Black HDD for general storage.
    I have set these other drives to "None", meaning no page file.

    I'm concerned about taking up valuable space on the Windows MVMe drive.
    So that's why I allocated the 850 EVO SSD to contain the page file.

    Will I be alright with just the one (1) page file.
    Could this kind of page file setup, potentially cause me any foreseeable issues down the road?

    One pagefile should be quite adequate. With conventional drives there was some limited benefit with having multiple pagefiles. The idea of multiple pagefiles originated at a time when the maximum size of a single pagefile on a 32 bit OS was 4 GB and in a busy server that often wasn't enough. With SSDs and an OS that supports a pagefile as large as 16 TB that need is largely obsolete. And with a reasonable amount of RAM the pagefile isn't going to be used enough to make much difference.

    Many people get a wrong idea of how the pagefile is used, being misled by the configuration dialog describing the pagefile. The impression is that Windows is madly reading and writing the pagefile, using it just like RAM. That is not the situation at all. Windows tries very hard to minimize pagefile usage, using it only for rarely used data which it is able to identify quite easily. This leaves more RAM available for more important purposes and improving performance.

    With a reasonable amount of RAM pagefile configuration matters little if at all. Most attempts at pagefile optimization are wasted effort. The only time it matters is if you have a heavy workload.

    From what you're saying,
    I gather that I need not worry so much about it and that the one page file I've allocated will do just fine.

    The image displayed no page file.
    If you are having any crashes or BSOD then you will want the page file on the same drive as windows.

    Event ID: 49 Configuring the Page file for crash dump failed. Make sure there is a page file on the boot partition and that is large enough to contain all physical memory.

    I don't understand what you mean by...
    "The image displayed no page file." ???

    I have not experienced the dreaded BSOD.
    My system is very responsive and is working well for me.
    I was merely trying to save space on my Windows drive,
    by moving the pagefile.sys.
    Without having any performance loss and or pagefile issues.

    This is another thing I don't understand,
    about your comment.
    "Make sure there is a page file on the boot partition"
    How do I do this,
    without taking up space on my OS drive?

    Also what is,
    Event ID: 49?

    Right,
    but why would I need to do this?
