 * Moving the Paging File **

//Myth// - "Moving the Paging File to a different partition on the same drive improves performance."

//Reality// - "Moving the Paging File (pagefile.sys) to a **different partition on the same physical hard disk drive** does not improve performance. Simply using a different partition on the same drive will result in lots more head-seeking activity, as the drive jumps between the Windows and paging file partitions. Even though moving the paging file in this case can have the positive effect of defragmenting it, the loss in I/O performance out weighs any gains. It is better to simply defragment the paging file using PageDefrag and keep maximum I/O performance by leaving the paging file where it is with a single drive setup. –

//Notes// – However you can enhance performance by putting the paging file on a **different partition and on a different physical hard disk drive**. That way, Windows can handle multiple I/O requests more quickly. When the paging file is on the boot partition, Windows must perform disk reading and writing requests on both the system folder and the paging file. When the paging file is moved to a different partition and a different physical hard disk drive, there is less competition between reading and writing requests."
