If there's ever a way to avoid writing small chunks to disk, that's preferred. But I think people are spoiled by having fast SSDs in their local machines, and much of today's software, web applications, etc. expect to be able to treat SSDs as RAM, pretty much. Once I can fully boot my Pis off USB, I'm planning on reworking my cluster to run off SSD alone to see what kind of performance I can get out of it.
