At least one vendor has been trying to sell me on these recently,
claiming higher bandwidth and better ability to seek. I have not yet
actually used these.

There's no reason to suspect that these are going to be terrible, they
appear to be the next step on the Seagate roadmap before HAMR drives
hit the market in the coming years.

I haven't seen much on the reliability side of things, however I 
wouldn't be too concerned, assuming that there's proper backup in place 
- Any other drive (including SSDs) could "just die" for a multitude of
reasons.

Hopefully there's some left for you!
