It seems that the technology is still on offer, e.g.

https://geizhals.eu/seagate-exos-x-2x18-18tb-st18000nm0272-a2883003.html

As for the price (and ignoring offers that are not in stock, or where
the offers vary wildly vary):

EUR Drive
427 Seagate Exos X - 2X18 18TB (2x9TB)
350 Exos X X18 18TB
440 2xToshiba N300 NAS Systems 10TB (total 20TB)
330 2xSeagate Exos E - 7E10 8TB (total 16TB)
385 10TB HDD + 8TB HDD (total 18TB)

So you pay almost as much as for 2 10TB drives, but get only 2 9TB
drives in one enclosure.  The power consumption may be better for the
2X18 drive, though.
