Page file recommendation

We have one server with 5GB of RAM, Windows Server 2008 R2, two hard drives in RAID 1 and one hard drive connected with USB for weekly backups. This server is Domain Controller and Exchange 2010 server. This server is not slow, but system uses page file and it is located on system drive.
Is it possible to disable using page file on this server? Can be server faster after disabling?
Or is it better to move page file to backup USB drive with free space?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Just leave it where it is.  All this Myth about paging files and speed.  If it only has 5GB of ram for exchange then depending on your user base size, you need that page file anyway.

Don't disable it. If you have space on the hard disk, use it.
I have a similar setup as you but I created a striped volume 10 GB before Raid-ing the disks. I put the pageing file there.

If you can have a disk on another disk controller, you can put the paging file there.

Considering your setup, I would put at least Raid 5 in the server and move the Exchange data and logs there. But best practise suggests splitting the Exchange data and the logs between disks.

I would not set it on a USB drive.
