I don't have any experience with the hybrid drives, and I don't know anyone that is currently using a hybrid.
If you want really fast try two SSD's in a RAID 0 striped setup. One of my game system configurations was two Intel 520's in a RAID 0 for a 240gig system drive. Boots in 6~7 seconds, shuts down in about 3 seconds. POST takes longer than it does for Windows to boot. Awesome fast, and even better when supplemented with a ramdrive for temp and cache files, as a ramdrive is more than 20 times faster than even an SSD.
DO, and I repeat DO maintain daily system images if you run two SSD's in a stripe, but that applies whether it's a mechanical drive or solid state. If either drive fails all is lost..... resulting in many cries of woe, a gnashing of teeth, and grown men openly weeping upon discovering their most recent backup is 6 months old.
