Back when disk-SSD hybrid storage was still a novel idea (~2006), one of the guys at Sun had an interesting demo with ZFS.
He first created a bunch of storage pools on a server on the east coast from iSCSI volumes on the west coast, install Postgres, and did a benchmark. He next created a pool with the same iSCSI pools but added a local SSD as a ZIL/zlog device (for caching), and ran the same benchmark.
The SSD-enabled pool has quite close to local-disk performance of a SAN.
