According to Stefan Monnier <monnier@iro.umontreal.ca>:
Hmmm, hard to believe it makes commercial sense: if you need higher
performance, when would this be price-competitive with an SSD?
[...]
It seems to have come and gone. Nobody has them new, refurbished are
$150 - $200 on eBay. An SSD of similar size is in the $2000 range so
it would have made sense for a data warehouse.
The prices I see currently are about CAD$16/TB for 3½" (~20TB) HDDs vs
CAD$80/TB for M.2 (~4TB) SSDs.
I guess if you need many TBs and you're content with a 2x speedup,
a dual-actuator drive can make sense, but I suspect that the market for
those whose performance falls between HDDs and SSDs is shrinking.
I wonder how power consumption compares for 20TB-range HDDs-vs-SSDs.
