I read some negative comments about sshd but when I read about them on the web there are not any negatives about sshd so are they good options or bad and why?

You have to take into consideration on who is saying anything (positive or negative) about them.
Yeah, a little hard to do on the web.
Myself, I will not use nor recommend an SSHD anymore. All the original ones I've used for myself or others have died (either fully or just the flash part...). And these were the ones worth getting too; with 7200RPM performance as the baseline before the cache could help further (if it ever did).
When compared to even a great HDD (7200RPM Hitachi TravelStars, or even WD Blacks...), the SSHD drives had an edge, no doubt. But when comparing those SSHD drives to even the bottom end SSD? The still performed like HDD's (relatively).
Now, take the price and their low lifespans into the equation and you can see they are just a wild goose chase for people with in-between money (more than a HDD but less than a full SSD). NOT RECOMMENDED.
Keep saving for a real SSD. I think it was over 4 years ago when Anand Lal Shimpi did a test of how much (SSD type) cache is needed to provide a HDD with substantial additional performance. His tests back then indicated at least an SSD of 256GB or larger (depending on the size of the HDD in the first place, of course).
The moral of the story? Forget about the promise of an insignificant amount of cache greatly benefiting a mechanical HDD. 8GB/16GB, 32/64GB and even 128GB or more is just manufacturers playing with you with a BOM to them of pennies per unit and charging you thousands of times more for a performance increase which can't ever come close to par in any real world workflow/workload scenario.
With my experience with them, this is how they stack up:
Good option for a platform that you don't depend (solely) upon, nor do you need the fastest 'experience', nor the highest capacity, nor do you care to save $$$ either. (Yeah; not a good option ever...).
Bad option for any platform where you want increased performance in all use cases (not just specific (and usually) 'synthetic scores').
Granted, today the price difference of even some SSHD's vs. HDD's seems to be almost negligible.
But keep in mind that you are getting a HDD that is at least 33% slower (mechanically), is more complicated and proprietary (i.e. prone to die...) and in the end; you still have the worst of both worlds: not enough cache (even with 128GB cache models) and still dependent on a mechanical platform. On a desktop, this might not be so important. On a mobile platform, a 100% solid state storage solution is worth it's weight in gold (for the robustness it offers, on top of the superior performance too, of course).
The above is also why I do not recommend an SSD+HDD solution for a notebook too. Not only does the HDD (to some; imperceptibly) slow down the responsiveness of the system as a whole, but it keeps the notebook in the dark ages of depending on mechanical storage (with it's less than robust track record) on a platform that is meant to be mobile. With a HDD; it's not (at least not to the degree the same platform would be with an SSD).
(Note; I mean actually using the notebook while it is being moved/jiggled/transported - not simply taking it from one location to another and then using it on a desk or other immobile platform...).
Right now, I can buy a 2TB + 128GB cache drive for ~$150. Or, I can buy an 480GB SSD for $30 more.
When is 480GB > 2TB? The sentence above.
And if you need more storage capacity? Buy an external enclosure for a few bucks and put in the HDD you have now. Not only will the HDD last longer in an external enclosure (if you don't have it plugged in continuously, of course), but your data may actually be safer from theft if it is separate from the actual system too.
If 7200RPM HDD's (TravelStar's) and 128GB or more of SSD flash was available on a single 7mm drive; it would be a no brainer. But that (ideal) combination hasn't existed for years, if ever. SSHD's needed to die out the second that 5400RPM based 'solutions' were the only ones offered.
(Even if there were no reliability issues to gamble with).

It is also about $70 more. For my budget, the Plus version is fine for me.
