GiliSoft RAM Disk can be part of a more SSD-conscious workflow on Windows when you move disposable cache, temporary folders, and other short-lived writes into memory instead of letting them constantly hit the main SSD.
Many users are not trying to protect every single SSD write. They simply want a practical way to keep obviously disposable write activity away from the main drive. RAM Disk makes sense here because browser cache, temp files, logs, and scratch data are often recreated anyway.
RAM Disk is not a replacement for proper storage and backup. The point is not to move important permanent files into memory. The point is to keep disposable write-heavy activity in a faster temporary location when that aligns with the workflow.
This page is strongest for users whose real intent is reducing unnecessary SSD writes from cache and temp activity rather than seeking a broad system-cleaner product.
