Good point. But the size of the PF is dynamic (if allowed to let Windows manage it, as most users should) and it needs room to expand, when needed. If restricted by a lack of free disk space, it can not expand as needed. This will force Windows to close files and save data back to normal disk space instead of "caching" it in the PF. Even with SSDs, caching and accessing ready-to-use data in the PF is much faster than saving and opening data files on the disk.Yes, except in the case of virtual memory your swapfile (pagefile.sys) remains unless you're wiping it at shutdown.
There was never such a "rule". That is, it was never about "percentages". That would suggest you need to keep more than 125GB free with a 500GB hard disk. Or worse, 250GB free with a 1TB disk. Those would be HUGE wastes of disk space.I don't know a heck of a lot about SSDs. I sorta picture the inside of one looking something like a circuit board full of a large bunch of memory chips. With no head travel, the 75% rule of thumb won't apply.
Sorry, but you are living in the past. This was an issue with first generation SSDs years ago. Today's SSDs don't suffer from such limitations unless maybe, they are used in a very busy commercial data center. Note that many SSDs are now warrantied for 10 years!!!! or 150TBW (terabytes written to any given sector on the disk). No home and most business users will ever come close to 150TB written to a single storage location on a SSD. And no hard drive warranty comes close.Allan10 said:Jim, given the hoopla about SSD's longevity based on write limits, did you happen to move all of the heavily 'written to', less critical, components off to an HDD?
Actually there was. If not exactly a rule than at least a rule of thumb.There was never such a "rule".
SOURCE:https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/defrag.mspx?mfr=trueA volume must have at least 15% free space for defrag to completely and adequately defragment it. Defrag uses this space as a sorting area for file fragments. If a volume has less than 15% free space, defrag will only partially defragment it. To increase the free space on a volume, delete unneeded files or move them to another disk.
I never said or implied I did either - so no apology needed. In fact, I have ensured it is enabled on my own system - at least for my boot drive. That said, I don't recall the last time I needed it on any of my systems - it has been years, for sure.Sorry Digerati
I don't believe its wise to run with System Restore disabled.
We do have a pretty good idea - to save space (because it is becoming a universal platform) and because W10 has other very robust and effective recovery features built in making SR less important. Because we grew up with it or it has always been there is no reason we cannot change. Change is good as long as it is not just for the sake of change. W10 is not XP (or Windows Me in this case - where SR was first implemented) and should not be treated like it.We will never know why MS disabled it by default.
Well it depends. The reason your PC become slow is the paging file get to big for the drive. If your computer has lots of memory it caches to memory instead of the HD. I remember when I first got a SSD I read not to have a paging file on the SSD but recently iI you should have at least some paging file. The best setting fot a paging file is to let Windows determin the paging file size and have lots of memory.I know when a HDD becomes nearly full the computer is slowed down. Does that apply to SSDs as well? I have about 5GB left on a 250GB SSD.
Ummm, not really. When free disk space becomes limited (HD or SSD) the problem is Windows has no room for temporary files. And Windows opens lots of temporary files when running and more temporary files are created whenever other programs are loaded. Any time you open any file for editing, a temporary copy of that file is created. And of course, browsing uses a lot of cookies and temporary internet files too.The reason your PC become slow is the paging file get to big for the drive.
Whoever told you that was wrong. SSDs and Page Files are ideal for each other.I remember when I first got a SSD I read not to have a paging file on the SSD

While the page file size is dynamic (if you let Windows manage it - and that is recommended) it does not change size dramatically enough to impact performance significantly. By far, the problem is a lack of space for temp files.
@ Jim If you only have 5GB free, you should definitely try to free some up. If you have CCleaner installed, run that. If not, run Windows own Disk Cleanup. Uninstall any programs you installed you don't use. Clean out your Downloads folder. If that still does not give you 20 - 30GB of free space, you will need to move some personal files or programs to a different drive.

See Support and Q&A for Solid-State Drives and scroll down to, "Frequently Asked Questions, Should the pagefile be placed on SSDs?" While the article is getting old, it still applies - even more so now since wear problems of early generation SSDs are no longer a problem.
