Over the years I have seen different opinions with regard to partitioning a hard drive.
Separate OS partition, separate program partition and separate data partition. Placing the paging file on the data file vs. The OS and program files on a one partition and the data on a second.
What are the advantages and disadvantages of each and/or there others.

Typically separate partitions each for OS/program files and for user data. So far as the page file goes, putting it on one partition or the other will probably have little benefit; however, putting the page file on a separate physical drive can help performance, assuming RAM availability is an issue.

Thank you. That is what I currently use.

my software can seperate it automatically
