Seagate Demonstrates HDD with PCIe NVMe Interface
Seagate has demonstrated the industry's first hard disk drive connected to a host using a PCIe interface at the Open Compute Project Summit. Like solid-state drives, the experimental hard drive uses the NVMe protocol to operate alongside SSDs seamlessly. Usage of a single protocol for different types of storage devices will greatly simplify datacenters.
The experimental [HDD] is based on Seagate's proprietary controller that supports all three major protocols, including SAS, SATA, and NVMe over a 'native NVMe port,' and does not require any bridges.
[...] Modern HDDs can barely saturate even a single PCIe 2.0 link, but future multi-actuator HDDs promise to be much faster, so 6 Gbps provided by SATA or 12 Gbps offered by SAS might not be enough at some point. To that end, the industry has to think about future interfaces to connect hard drives, and PCIe seems like a natural choice. Furthermore, as SSDs are gaining traction in datacenters, the NVMe protocol becomes pervasive, so it makes sense to adopt it for HDDs. This is why NVMe 2.0 adds hard drive support.

"So the question is, is that model terrible with widespread problems or did you have an isolated problem (and a manufacturer not standing behind the product)?"
Only the single model total garbage, I still have three of the drives that replaced them drives going 10+ years later. The others were sold off after upgrading to larger models which have since been upgraded to larger models two or three years ago. Out of them dozen or two only a couple have failed both still under warranty if my memory is correct. Them Seagate drives as I said only one in warranty the rest just out of it. As long as I live they will never get another cent of my money.
