It helps, but the bigger win is performance.

Yes, more RAM means less swapping, which means fewer writes to the SSD. But unless you’re constantly maxing out your current RAM and seeing heavy swap activity, the wear reduction is small. Modern SSDs can handle hundreds of terabytes of writes before dying. Your swap file adds a few gigs a day at most. You’re more likely to replace the SSD because it’s too small or slow, not because it wore out.

The real benefit of 16GB is that you stop hitting the swap file in the first place. No stutters, no lag when you have ten browser tabs plus Slack open. That’s a tangible quality-of-life upgrade.

Buy more RAM for speed, not SSD longevity.
