HAMR has a theoretical areal density limit ranging from 5 to 10 terabits per square inch, enough to enable 30TB to 60TB 3.5-inch drives and 10TB to 20TB for 2.5-inch drives
From previous article about this tech from Seagate.
In reality do not be surprised to see 10TB and maybe 20TB 3.5 inch desktop drives in this timframe, but I for one WOULD BE surprised to see 40TB let alone the "in theory" 60TB.
Having said that, I'd be extremely happy with a 10TB desktop drive.
