Given that not implementing barriers is basically a bug in the hardware [for SATA or SAS], I don't think anyone's going to specify anything other than "fully suppors barriers" in their datasheets. I don't know of a testing tool. It may not be obvious that barriers aren't being honoured without doing things like power-failure testing.
