[GTALUG] Recommendations for a root filesystem

I'm running Fedora, and want a filesystem with a write cache that I can put on flash, as I occasionally run some evil write-intensive tasks. I'd love to simulate the Sun trick of flash for write cache and ephemeral for read cache. Alas, my brain is roughly at the samfs/qfs level (a predecessor of zfs) and it's not clear what of the more modern filesystem I should consider for everyday use. --dave -- David Collier-Brown, | Always do right.
