SSD and Windows FastStartup
-
Disables both because it also deletes the hiberfil.sys file. That's why I like to use it. Gets rid of a 6.8GB file off my SSD.
That's good to know. What would happen if you don't disable hibernate with the powercfg -h off command..but instead in advanced power settings you set hibernate to Never and Allow Hybrid Sleep to Never, also ensuring that Windows Fast Startup is Off. Would that still leave the hiberfil.sys on the SSD but because it had never been used it would just be an empty file? I have 8 GB of RAM so from what Ive read the size of hiberfil.sys could be up to 6 GB (75 % of RAM). Would that still increase the usable space on my SSD by 6 GB...or because the hiberfil.sys file still exists on the drive would it be reserved for hiberfil.sys in case I ever use Hibernate at some point?

According to that tutorial, the correct command is powrcfg -h off
--- My mistake: it's powercfg -h off
I know my comment is repetitive but I brought that up because post #8 is -off vs off
"My PC is a desktop not a laptop. Does the powrcfg -h -off command disable hibernate or hybrid sleep?"
Thats my fault for causing your confusion. I made a typing mistake!! It must be my age! lol

Unless you are using cheap SSD's with no DRAM and/or SLC/3D cache as boot drives I wouldn't worry too much about how much cache/writing goes on.
My oldest, 6 year old Silicone Power el cheapo SSD already has 76TB written to it and is still 100%. They are not as sensitive as people think, in any case, no need to treat them differently from mechanical HDDs.

I don't use any sleeps. I just have all relevant power settings to "never" "none" or whatever! Depending on the type of SSD you have you may also look in to disabling Superfetch and Prefetch and also if you can Search. All three of these use the drive unnecessarily.
I really dislike the indexed search and rarely use it anyway, so I just have it disabled. It slows down searching but I don't mind that. Prefetch and Superfetch have some benefit if you use a SATA drive but they have virtually no benefit for a PCIe drive.
Bear in mind there are three tasks that need to be stopped which if I remember correctly ( please check ) are
Search, Prefetch, SysMain.

3 year warranties typically on DRAM less, 5 on DRAM + SLC Cache. They are different for a reason.
I was reading recently about a data service that lost three SSD's from a server RAID array simultaneously, not an easy rebuild...
When they go it tends to be instant (been there), at least with an HDD you generally get a bit of warning, so they aren't the same thing at all.
A boot drive is going to far more 'busy' than a backup, so why skimp on the specifications if going solid state, especially as price isn't the major factor it once was?

And reason being to charge more for them

Over here in the UK the premium is negligible these days, I still buy the DRAM less cheapies for USB external backups et al, but wouldn't use for boot C drive.

I concluded on my SSD based PCs that fast start-up isn't much benefit so I disabled it and also hibernation which I never use - use the command powercfg -h off
Same here, disabled fast start and hibernation. I have fast SSDs and fast start makes little difference. I want the computer to do a full reset when I power down anyway. Fast start reloads portions of the operating state into memory which can cause trouble over time. With fast start enabled powering down doesn't fully reboot the computer.
Don't really need hibernation, I always power down my computer when I'm done using it. There may have been a time where cold starting was a wear consideration, but now with everything solid state it doesn't matter anymore.

I've had issues with VM's using sleep/hibernate in the past, and some similar issues in W10 with fast start, but I just use 'restart' for a cold boot if I suspect that's what the issue is.
What would be handy when selecting 'shut down' is if there was an option for fast start / cold boot on next boot or some sort of scheduling so that once a week a cold boot was initiated automatically, overriding fast start.

"I have 8 GB of RAM so from what Ive read the size of hiberfil.sys could be up to 6 GB (75 % of RAM)."
Because I do what NavyLCDR does I've never checked that out.
--- However I suspect the "up to 6GB" applies to the space on the drive, not against RAM.
--- If I'm wrong I'd like to know
