Seagate SSHD Firecuda

I currently have a 2TB unit sitting in a TB2 external enclosure that is my boot drive. HS kept is HFS, but with Mojave, the upgrade converted it to APFS. No issues so far running Mojave Beta. HS did not support APFS on anything other than straight SSD.
So, likely even as internal drive, HS would keep it HFS.

Aren't SSHDs notorious for the having a hard time moving data to and from the SSD? Guess I'm just wondering if the performance gains on an SSHD aren't worth additional risk? Is data recovery from an SSHD as straightforward as a spinner?
I have used several over the years.
In general, speeds are somewhere between SSD and HDD. They tend to make these with relatively small SSD and claim to write to SSD then move HDD whether is limited activity. How well they are able to do this is probably dependent on a few factors. In my experience, at first they are a bit slower, then speed up as hey learn the most used files to keep on SSD. Boot times are reasonably fast. I suspect if you use a lot of large applications regularly, versus a handful of smaller apps, they may tend to be a little slower as more of the frequently used stuff will have to be stored on HDD.
The OS sees SSHD as an HDD. All of the disk swapping is done within the drive's internal controller. I have had no issues, so not sure what risks you may be referring to. Recovery is identical to HDD, albeit perhaps a bit faster due to generally faster read\write speeds.
Bottom line, you will see some speed improvements, but not as much as SSD. But, the price is the tradeoff.
Ok thanks. I think I'll give it a whirl. Just try to make sure I have some Superduper clones made with frequency. Always get a little concerned that there is more risk of failure involved than a tried and true spinner but am intrigued by the performance gains so we will see.
Yes very much so I am running Seagate Firecuda Hybrid Drives on my iMacs with APFS. I can also confirm full compatibility with Mojave.

Firecuda Hybrid drives support APFS on High Sierra just fine. I have them installed on two iMacs.
SSHD is not Fusion drive. The SSD part only serve as cache. All data stored on the HDD. Then some of the frequent accessed data will be COPIED to the SSD part to allow for fast reading. NO data MOVING.
Therefore, SSHD won't be benefited from APFS. In fact, the additional metadata handing may slow down the SSHD due to the HDD part is very bad on handling this kind of small and fragmented data.
