Nope as in the SSD will still not accellerate the retreival/writing of data for the SSHD.

Virtual Memory/Swap File, whatever you want to call it isn't designed to cache hard drives on the SSD and you should probably read up on what it really is used for.
In-fact you would wan't to avoid lots of small writes on an SSD for things like Virtual Memory/Caching. - Why? Wear and tear. SSD's have a finite amount of write cycles, it's wise to minimise your Virtual Memory, disable things like Superfetch.
There is a reason why the notoriously unreliable OCZ Vertex 2 in another machine of mine is still running as strongly as the day I bought it many years ago. (I was an early adopter, sue me.)

In short... There is still a benefit to owning an SSHD over a mechanical drive even if you have an SSD as the main.
I know this, because I have all 3 and have done extensive testing in memory management, the pinnicle of which being a Ram drive.

I think I really failed to explain myself the first time because I got two people trying to correct me, and I don't think either of you understood my original point. :P Yeah, I meant SSD caching (despite talking about swapping because I'm bad with storage-related terms) and how I believe it should be equivalent to owning an SSHD. That is, to me it would seem that using SSD caching (SSD for cache + HDD for actual storage) should be roughly equal to having an SSHD performance-wise.

I do realize SSD caching is going to be stressful for the SSD, but doesn't the SSD component of an SSHD face the same problem?

They use different NAND and wear levelling mechanisms, so it's not Apple to Apples.
The controller tries to avoid writes as much as possible, so once it's worked out what stuff you use most frequently, it will be cached and minimal farther writes made.

As for SSD Cache drives, it's actually a better experience than an SSHD, I have a Sandisk Express Cache in another machine, the main advantage is the size of the SSD, which means more is aggressively cached. And boy can you tell the difference if the SSD cache is turned off. The NAND is also higher grade, faster.
And because the drives are fairly large, it can do better wear levelling to prolong life.
