"EAMR offers similar density gains to HAMR and MAMR, with less exotic

Wow, that reminds of the good old Prime mini days with the $250,000
twelve platter twelve inch hard drives.

SSD is definitely coming on strong.* I keep on wondering if the
holographic media is ever going to be useful.


The amount of trickery needed to keep increasing the HDD's capacity is
starting to become unsustainable: SMR, HAMR, MAMR, EAMR, etc. It's
starting to look like, that among magnetic recording technologies, tape
is going to end up outliving HDD's, even though HDD's were originally
intended to replace earlier versions of tape. Even the main advantage of
HDD over tape, random access read or write performance, is no longer
that much of an advantage, as HDD's are starting employ technologies
that make them horrible random access writers, negating their advantage
over tape. It's going to be SSD's and tape only from now on.
