Hmmm, hard to believe it makes commercial sense: if you need higher
performance, when would this be price-competitive with an SSD?

Also, that page is very light on details, but the image they include
suggests the two actuators are used on separate platters, so it's akin
to cramming a 2-disk-RAID0 into a single HDD enclosure.

The data sheet says it is in effect two 7TB disks in a single enclosure.

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.
