This has been a very effective approach for us lately. We've built 
client systems with relatively small SSDs with centralized storage (this 
usually just means mounting /home over NFS4 or AFS) and its worked very 
well. In a single system this could work just as well by pushing things 
like /home (and /var depending on what you're up to) to the huge 
spinning disks and installing everything else to a tiny SSD.
