Announcement of 6TB HDD From Seagate Imminent

Seagate could reveal in few days that the company will offer the availability of a 3.5-inch 7,200rpm HDD this quarter at 6TB, a record reached only by HGST using helium gaz.
Seagate is not in helium technology and it could use SMR with six platters for a cheaper price than HGST helium drive.
But there is no reason to use helium with SMR into the same device and then HGST will have the possibility to beat the current 6TB limit merging the two technologies.
This Seagate's 6TB unit could be revealed for the first time for an external drive.
"We are continuing to expand our offering of high capacity drives with our 6TB drive shipping early next quarter," said Steve Luczo, chairman and CEO of Seagate, during a conference call with financial analysts last January.
