Windows 7: Pagefile

26 Feb 2010   #1

W7 Ulti/64, XP Pro/32

I have 6gb's of ram, do I need a pagefile? Played a little and turned it off but I noticed that there was some kind of usage in the performance monitor, still. Currently use 3 SSD's in RAID 0, with a 4th for pagefile and temp files.
Do I add 4th SSD to the RAID 0 array?
Do I go RAID 5, using the 4th that way?
Do I use the 3 SSD's in RAID 0, with the 4th for pagefile, as it is now?

RC1 is dying so I have purchased W7 Ultimate 64 bit and I am getting ready for a clean install, thats why the questions.

Yes, leave the pagefile.
Many programs expect and want a pagefile present.

Some will say say leave it as it and dont touch it.

I see nothing wrong with reducing the size and making it static with large amounts of RAM, but do not disable it.
With 8GB I use 768MB pagefile.

If you have the room, Pagefile would be best left on the SSD.

really a personal choice I think on how to set it up and how many other drives you have.

Im sure youll get many different viewpoints, some likely better than mine but:

If it were me I would just run RAID0
Disable Win7s Defrag Shedule .. and disable the Superfetch service. (7 may do this on its own but sometimes it doesnt)
Possibily change the Pagefile to either 768 or 1GB Min and Max.
Thats It.
Newer Gen SSDs do not need alot of tweaking. Moving TEMP Folder is OK if your really in need of space. But Id leave it where it is if you can.
then use a spinning drive for all backups, (FULL disk images) and backing up often

What kind of SSDs did you get? :)

It's recommended by Microsoft to set the pagefile to 1.5x the amount of physical ram installed, Windows does this by default. However, moving the pagefile to a separate physical hard drive and setting the initial and maximum pagefile size to be equal can result in better overall system performance.

I have been using 30gb OCZ Vertex, FW 1.1.
Intend on FW 1.5 update, before clean install of W7.

Yes, 1.5x is recommended, but doesnt really need to be that large when your talking 4GB of RAM+
W/4Gb Id use around a 2GB PF though.

Moving the pagefile off the SSD to a spinning drive is going to hurt performance, as any spinning drive is much much slower.
Although with 4GB + RAM, youll seldom ever use the PF anyway, when you do, it will have to wait for the spinning drive to spin up and seek.

Those Vertex with FW 1.5 will do an excellent job. If your going to RAID them, Id do as I suggested earlier. They will serve you well.

If running just a solo 30Gb vertex .. then yea .. Id move the Temp Folder, disable Hiberfile etc because space will be cramped.

So long as you have at least 2 of them in RAID, It should no longer be a issue.

Flash them all to 1.5 seperatly, in IDE mode, before you set up the RAID.
I would also sanitary erase each drive after the FW update as well before setting up and installing windows

Wishmaster, he clearly stated that he has 3 SSD's on Raid and a 4th for Pagefile and that's the way he should do it. Having all 4 SSD's on Raid would not have the same effect on the Pagefile as having the Pagefile moved to on a separate SSD dedicated for the Pagefile.

on a spinning drive, I agree, moving the PF to a seperate drive can help some.

However, SSds have near 0 access times, no spin up time, and much faster read rates.
In a Raid array they are even faster.
You're still moving the Pagefile to a slower drive. 1 SSD VS 3 in RAID0

As long as theres room, theres no reason to move it away from the
Solid State RAID array. it will only hurt performance when the PF is needed, not help.

Whatever, I do not totally agree with you but I also do not want to go on arguing. Let him decide what he thinks is best. I'm done you hear?
For the sake of reasoning:
Raid 4 SSD's = 0.x access time, Pagefile with System Files
Single SSD = 0.x access time, Pagefile seperate from System files

As you have been advised, leave paging memory decisions to MS. They have much more experience in this area. Reset your system to the defaults and never, never, never mess around with it again.
