I just put two of these into a FreeBSD box. Each drive shows up with the MPS driver, but haven't tested ZFS yet since I don't know how I want to carve them out. Just an FYI, the ddcli tool you'll want to use in FBSD is on the Seagate Nytro WarpDrive download page. The firmware for mine is too old for the latest utility, so I had to pickup the previous v12 release.
