I've heard that using the last 10-20% of SSD space can slow it down, but I'm wondering what happens if I allocate 10% of my 500GB SSD for virtual memory. Specifically, if I use 25GB for virtual RAM and leave another 25GB untouched, will the remaining 450GB of data still run as fast as if I hadn't used any of that SSD space?

Realistically, if Windows is already using your SSD for virtual memory, it’s best to let it do its thing. You can check your system settings and see that the pagefile is automatically managed. Also, it's recommended to keep about 20% of your SSD free to minimize wear and tear. No need to complicate things!
Using your SSD for virtual RAM, often called swap space, is pretty standard. However, keep in mind that while it’s possible, SSDs are significantly slower than actual RAM. So, you'll likely see a performance hit if it comes to relying on that virtual memory.
Drive speed isn’t the main issue; it’s more about the longevity of the drive. Major operating systems already allocate space for these functions. Plus, SSDs have limited write cycles, so using that extra space could shorten the lifespan of your drive. It’s usually better to keep that free for performance and wear-leveling.
You can use part of the SSD for virtual RAM, but if you do use 10% of your space, you might face performance issues down the line. It depends on how your SSD manages data and firmware. For optimal performance, it might be best to run some tests yourself.
What you're talking about is essentially what a page file does. Most operating systems, like Windows, handle this automatically by using a portion of your SSD for virtual memory when needed. So you're not really doing anything out of the ordinary here.
