In Reply to: RE: It's a Hitachi HGST helium filled drive posted by AbeCollins on July 26, 2014 at 21:34:32
the Helium drive is 300 dollars more and has the HGST label, not the Western Digital name. Although HGST is owned by WD....

You're right. I assumed that WD just relabeled their HGST drives. The WD drives use plain-ole "Perpendicular Magnetic Recording" (PMR) technology with no helium to reduce friction / power consumption.
Drives using PMR are at the limits of physics and bumping the limits of maximum capacity. Manufacturers are looking at other magnetic recording technologies to go beyond these limits.
