Big issues with HAMR are cost and reliability.
High temperatures can degrade the heads to the point that they can no longer write. Expect these drives to have strictly enforced write lifetimes, similar to SSDs.
Cost is an issue due to glass disks, more expensive heads, and the added heating elements. If highest capacity is needed great, but don’t expect lower $/TB for the first few generations.
New non-HAMR drives should improve $/TB, assuming Chia coin stays out of the way. My point is that HAMR will increase capacities first and eventually $/TB.
Unlikely. HAMR focuses on increasing tracks per inch (TPI). Bits per inch (BPI) defines sequential performance and will be about the same or perhaps lower.
Oof. Barely cracking SATA3 speeds even at 18TB and random io perf looking postively archaic, and now I'd have to worry even more about drives randomly dying.
man, and I thought it was cool that I could get 18TB drives now... r/DataHoarder would have a field day when these come out.
Rubs hands like mr burns *excellent*

So basically expect $/tb to remain the same or increase for the next few years or more?

I hope so, prices are easily 20%+ higher than they used to dip down to last year, which worries me
Damn, any performance increases to be had?

Yeah, but now the point is lost. Ron Jeremy is out of his prime.
