In which of the following places is it BEST to put the paging system file?

Placing the paging file (swap space) on a separate non-system partition, ideally on a different physical disk, helps to reduce I/O contention. This separation allows the operating system to perform read/write operations for virtual memory without competing with the system files and applications that are actively being accessed on the system partition, leading to better overall performance.

Placing the paging file on the system partition (where the OS is installed) creates I/O contention, as the OS and applications constantly access files on this partition, degrading performance.

While a flash hard drive (SSD) is fast, placing the paging file on the *same* physical flash hard drive as the system partition still introduces some I/O contention, and repeated writes to an SSD can also reduce its lifespan more quickly.

An external hard drive typically connects via USB or similar interfaces, which are often slower and less reliable for continuous system-critical operations like paging compared to internal drives.
