Pagefile configuration for two drive system

by juanfhj / November 16, 2008 11:39 AM PST

Greetings. I have Windows XP with 2048 memory, 4096 pagefile, and two drives. My "Program Files" and "Windows" directories are in C: . The "My Documents" directory is in D: . I'm yet to decide whether to place my pagefile in C or D. I thought the most disk activity will occur in C: , so D would seem the best choice for pagefile, but I'm not really sure about this. Any hints?

Not worth it

It's not worth it to bother. If it's an IDE drive, you won't really gain anything performance wise, and I honestly don't know if SATA got rid of the "one device at a time" limitation of the IDE bus or not, but even if it did you're going to see very little in the way of performance increase.

Put very simply, the fastest hard drive there is out there is still thousands of times slower than pretty much every other part of your computer. You just aren't going to get that much out of it, period, so there's no point spending a lot of time obsessing over how to best arrange things. Just let Windows manage the swap file, put it on whatever drive you want, and forget about it. You'd be almost infinitely better off just adding more RAM.

Agree with Jimmy . . .

Leave it alone. In the rare instance that the drive with the swap file is completely full, then you might consider moving it or adjusting it. But, again, let it be and let Windows handle it.

I messed with mine a while back, and I have an IDE master and a SATA slave. Moving the swap file around was a PITA and I did not see any difference.

If my poor memory serves me well, I seem to recall that when placing the page file on a slave drive for faster vitual memory access (really not worth the trouble) that it should be placed on a dedicated HDD, as in a HHD that has nothing else on board except the pagefile. Also, again if my poor memory serves me well, in addition the main drive must still have a local page file as some application require it.

Well yeah
by Jimmy Greystone / November 17, 2008 8:13 AM PST

Well yeah, if you want to do it right, you'd put it on a dedicated drive, that is also the only drive on a given controller if IDE. But again, ultimately the gain is so minuscule it isn't worth the effort required to set it up.
