32GB RAM is usually enough for a RAM disk for temp files.

Yes, but only if you actually have that RAM to spare. A RAM disk borrows from your system memory — if your OS and apps are already using 20GB, you only have 12GB left for the disk. That’s still plenty for most temp files: browser caches, compile artifacts, even small virtual machine scratch space.

The real question is whether you have enough RAM after the disk is set up. If you carve out 8GB for a RAM disk and your normal workflow leaves you with 10GB free, great. If you’re regularly at 85% memory usage without the RAM disk, adding one will just make everything swap and slow down.

So 32GB helps, but only if your peak memory usage (including the RAM disk) stays under ~28GB. Otherwise, you’re better off with a fast NVMe SSD and letting Windows or Linux handle caching on its own.

Don’t buy more RAM just for a RAM disk unless you’re doing something specific that actually benefits — like video transcoding or large database queries — where the latency difference matters. For ordinary temp files, a good SSD is almost as fast and way less hassle.
