Helping people with computers... one answer at a time.
The paging file and hibernation file can be turned off. Whether it affects the speed of your computer will depend on how heavily you use it.
There seems to be a debate all over the web and I can't seem to get a straight answer. I know you covered page file on your website. But can it be disabled, even deleted, if you're using an SSD drive? According to some forum pages, they go so far as to say it's useless along with super fetch and hibernation all in an attempt to free up space for a 60 GB SSD. I thought this would be plenty of space when I ordered my laptop only to see it have 30 GB free the day I received it in the mail. Using Windows 7, 64-bit, and it has 8 GB of RAM.
In this excerpt from Answercast #17, I talk about freeing up disk space from the paging file and what may cause you to decide to turn it back on again.
With 8 GB of RAM, it is certainly reasonable to consider turning off the paging file. The short answer is, absolutely, you can turn it off.
The way to do that is to go into the paging file settings and then set the paging file to zero for all drives.
That way, when you reboot, the system won't even try to create one. If there's an existing paging file, you can then just delete it. Just go look at it; delete it like you would any other file. It won't be in use like it normally would and you won't be prevented from deleting it.
If you've got 8GB of RAM, that could be more than enough.
I ran my desktop for a couple of years with no paging file with 8 GB of RAM. Only recently did I turn it back on because I was starting to do a few things that occasionally would push me past 8 GB of RAM usage.
I think my laptop that I'm recording this on today also has 8 GB of RAM and I believe I have the paging file turned off here too. It works just fine.
What it boils down to though, is that it really depends on how you use your computer:
If you run a lot of software simultaneously.
Or you run software that uses a lot of memory.
On my desktop, I was trying to run several virtual machines at the same time. Then, you may need a paging file.
But if you're not, if you are just doing the standard stuff like surfing the web, checking email, and some simple things like that, then I'm sure you can get away without it.
Hibernation? Again, yes.
That takes up disk space because it will create (in your case, and in my case) an 8 GB hibernation file.
A hibernation file is basically the size of your installed RAM. I never use hibernation so it's a feature that I immediately turn off when a laptop arrives. That then allows me to go in and delete the hibernation file: hiberfile.sys. So, those are a couple of ways that would free up a fair amount of disk space right away.
The other alternative, of course, if you've got a hard disk in the machine, is to move the paging files and hibernation file (in particular) to a different drive.
But then if you start saying, "Am I really getting the speed advantage I wanted out of my SSD?" ...if you want this speed advantage, you kinda sorta want the paging file on the SSD.
So, it gets complicated, but absolutely, you can turn them off.
I recommend that you do so immediately. You probably also want to start taking a look at what other kinds of things are on the C drive that may be moved elsewhere, or removed, for space savings.
I have an article I would point you at, "What
are hiberfil.sys and pagefile.sys? (And how do I remove them?)" That will
run you through the steps to turn both of them off and remove the files:
freeing up the disk space.
