Never, never, never do this.
The purpose of a page file is to off-load data from the RAM.
This double-taps the RAM, over utilizes it, and reduces overall performance.
It's basically taking a piece of RAM away from the system, setting it aside so the rest of the system can't use it, and then putting stuff the RAM is trying to get rid of back on the RAM with no fall-back option in case it gets overloaded.
This is the fastest way to get page faults and then end up with thrashing until the system crashes (in low RAM environments).
This also introduces potential issues that can occur when disabling the page file (primarily inability to preserve system dumps in case of crash).
If you have enough RAM you can
disable the page file for a marginal performance increase in some areas with the risk noted above.
Some people prefer this, although the safest option is to leave a small amount enabled regardless of your setup.
If you are working in a low RAM system, the best performance option is to keep the page file on the SSD, although many people prefer to move it to HDDs to reduce disk writes for the SSD. That isn't as much of an issue with modern SSDs and slows down page file access (since HDDs are slower than SSDs), but like with most things, it's a matter of preference.
