Drive-managed SMR looks OK to me for general use, although I don't have hands-on experience with it. They also have a non-shingled region that can accept random I/O at higher speeds, and the drive deals with moving data to a linear-only region once it fills up, or at garbage collection time.
It's very much like the QLC drives where a portion is treated as SLC/MLC.
It's like the QLC drives with SLC/MLC cache (e.g., Intel 660p) except the performance cliff is far, far worse (and obviously the "fast" mode is far worse as well).
