You're probably still correct, but what I saw from the immediate next generation was something like 9 platters and two or more independent read/write heads.

So we might be headed for what used to be a single write head (and its single throughput stream) to double, triple, or more.

Especially since the additional read heads enable the datacenters to scale shared object storage more effectively with more dense drives, which seems to be the main customer/application for HDDs at this point.
