That's what I'm wondering though. Nearly all the WD data center drives are marketed as Ultrastar. Is this marketing, or did the HGST entity supplant WD enterprise during "integration" in the last two years? link It looks like the only surviving product names are Ultrastar and CinemaStar. Nothing is labeled HGST anymore. Most of the HGST Helium disks were SMR, if I'm not mistaken. As of now, given the two HelioSeal series, one of the two is SMR. Side Note: Hitachi had such a great thing going with their Schoolhouse Rock meets Dino DNA commercial. I wish this would have continued. this video
