second disc is always better then the os disc if it's not being hit as much, if it's always being, for instance if it's a network server everyone is accessing then maybe not but usually the os hardrive is the last disc to put the pf
don't forget, if you want to collect dumps then leave a small pagefile in the c partition even if you put the larger pagefile on your secondary disc
also make sure the disc you set your pagefile is not configured to spin down if unused, however it's going to be used if the pagefile is on it but still
how r u doing?
