1. Win 7 is supposed to turn off Hibernation files automatically once an SSD is detected. So yes turn off Hibernation and it will delete the files on its own.
2. Yes you can move the page file system to a different drive. I did this to keep the ware down on my drive.
3. The benefit of leaving it on the drive is access speeds although I have never noticed a difference since switching it to a different drive.
P.S. After switching page files from one drive to another you will get an error in Event Viewer to due with page files. From what I have read, this is normal if the page flies are not on the OS drive. Just be aware that it poses no risk just annoying when looking through the Event Viewer.
Thanks for the reply! I freed up 30 GB on my SSD!
