I have several of the 2TB and 4TB variants of these drives running and they are very good with sustained writes as you would see while recording in myth.

Good to know.  I knew it was TGMR, but didn't know if that was mutually 
exclusive with SMR.  I didn't know if TGMR was a lower-level recording 
method which can be shingled or not shingled. Does that mean that SMR 
uses SMR-specific recording heads, and any other recording method 
specified is not shingled?
