The main problem with a cache is that you need to be able to hold frequently used stuff in the cache, so that it can be repetitively reused once you have loaded it from the slower drive.
If you can do that, then you might as well do one step better and store those things on a ssd in the first place.
The best circumstance for a cache is some sort of pattern where you intensively use one set of data for a while, then flush the cache and use a different set of data repeatedly.
I think those situations are not common, and probably not recognized even if they exist.
Again this would be the best choice since it uses both....I have done tons of research on this matter for my laptop and my desktop and use them in every system I own and they work without a hitch. They have the speed of an SSD and the storage of a HDD. Even if they are not recognized is no reason to put down another persons answer when they are just trying to be helpful. You might want to think about how you respond in order for you not to offend people in the future. Just a friendly thought.
I don't think geofelt was trying to offend you, merely just stating his opinion on why a hybrid drive isn't viable in this situation. You must realize that just because someone disagrees with your opinion, doesn't mean they're trying to offend you.
On topic, I would go with the SSD, I switched to a SSD back in 2010 and wouldn't go back.
