Paging file - another partition

I have 768 MB RAM, and I moved pagefile from C: partition to D:. (C disk is
45 GB and 7200 rpm, and D is 20 GB, 7200 rpm too). Is this good idea?

Changing partition doesn't give any performance gain of itself.
If that partition is on another disk and that disk is on a separate 
channel or controller and is less active than the original, then you may 
see a performance gain ( assuming you are doing a lot of paging in the 
first instance. )

Ups, my first e-mail wasn't complete:
Primary master - disk - 7200 rpm (operating system)
Primary slave - CD-ROM
Secondary master - CD-RW
Secondary slave - disk - 7200 rpm (there is page file)

CD-ROM and CD-RW isn't all the time in use (once per week).

Is this OK, or I must change position for CD-RW and second disk?

What is suggested size of pagefile? I have 768 MB RAM.

In your scenario, you are still talking about two channels on the same 
controller.  I couldn't see you gaining any performance.  As for the page 
file size, there several opinions on this, but the general consensus is to 
set the upper and lower limit to be double the size of your RAM (unless you 
are talking about a very large amount of RAM).  Set yours to 1536 and you 
should be fine.

I understood his post to state that the 2 hard drives were on separate 
controllers, 'system' drive on Primary Master and 'paging' disk on Secondary 
Slave. This arrangement should show a performance improvement if there is 
any to be gained as the 2 devices are indeed on separate controllers and the 
OS and remaining hardware can/will use both of them simultaneously. If they 
were both on the same controller (same cable, one master and one slave) then 
only one device can be active at any one time. If little paging occurs 
anyway, you will experience almost no difference in performance, 
irrespective of how the drives are connected. If they are on seaparate 
controllers now, leave them like that.

Re-read his post.  The way he has stated it, it is very likely an IDE setup, 
which will be one controller, two channels, primary and master on each 
channel.  Otherwise, it should have been stated as separate SCSI controllers 
with dual channels.  At any rate, I would find it very difficult to believe 
in an SBS environment, with anywhere from a few users up to 75 users, there 
will be a noticeable improvement in performance for day-to-day operations.

True for older systems, but not so for "Modern" devices.
