The reason is that when you have a pagefile split across several volumes, the VMM chooses the least busy drive for writing pages to disk, which in our example would mean the pagefile on E: would almost always be used since C: has a lot of system activity. And, by the way, always restart the computer after moving or reconfiguring the paging file, even if Windows doesn't prompt you to do so.
Otherwise some Windows utilities may display an incorrect value for total pagefile size.

Over 1,, fellow IT Pros are already on-board, don't be left out! It is 6 GB drive. Also, I read online that if I have RAID, then there is no much difference in moving paging to diff drive unless its on separate controller. My rule of thumb for years has been to keep the page file off the system drive, but realize that if you get a blue screen you won't get a complete dump file.
That is worth the risk, imo, becuase I could go back and reset it and wait for the next blue screen. Second, there is no reason not to have multiple page files on multiple drives. Can't produce the document now, but there is one, or used to be one, that notes that Windows is smart enough to use the "least busy" drive.
Note that "spindles" is really what this is about, not partitions. Having said that, the best option for busy networks, imo, is to have a dedicated drive for page, and maybe WSUS data which is seldom written to when the troops are busy on the network. Thanks for the response.
So based on structure of my harddrive, you are saying I can set "H" drive for page file and then set rest of drives to "No Paging File". Yes, you are correct that if all your partitions C, E, F ,G, H are all on the same set of Raid-5 drives, that there is no performance gain.
However, people usually look to moving the pagefile away from their C: drive when there is not much free space on the C: drive. First, you said the paging file was on your C: drive, but now you say it's on your H: drive. Could you please restate what your problem is or what you are trying to accomplish?
Even if you move your swap file off the C: drive, it may be good to maintain a small swap space mb as Phillip suggested. All I m trying to accomplish better performance of memory because I have Quad Core processor that I dont want memory to be bottleneck of the system.
As to the H: drive, this is what you wrote: "I read somewhere to create a separate drive for paging and that's what I created H.
As to memory usage, that's what memory is for -- to be used. Your pagefile isn't an issue with your server performance or memory usage right now. Go ahead, move it, and get going with implementing your server. Well I meant to say that "H" drive is set aside for paging purpose. Change the name of the value entry so that it points to the drive letter you want to use. If that drive letter is in use, you must rename two value entries.
For example, if you want to rename D as C and C is already in use, you must rename C to an unused drive letter and then rename D as C. Afterward, restart the computer. After you make a change, the new drive letter or mount point assignment is made automatically as long as the volume or partition is not in use. If the partition or volume is in use, Windows Server displays a warning.
You must exit programs that are using the partition or volume and try again or allow Disk Management to force the change by clicking Yes when prompted. To add, change, or remove a drive letter, right-click the primary partition, logical drive , or volume in Disk Management, and choose Change Drive Letter And Paths.
