yeah if you running out of ram and need pagefile, then as fast as you can get it good.
and hard drives are very bad for it.
I’m running 2 x 950 in raid 0 for my pagefile. but just getting a single ssd will make a huge difference.
in the past I’d run in on hard drive and single ssd. the biggest jump is getting away from hard drives and their terrible response times.
also having temp drive on ssd is good. but page file is more important to be fast. you could probably get away with both pagefile and temp on same drive if it had enough space. it doesn’t seem to hit them both hard at the same time.
