Is this available without the drive? If not, what's the make and model for those who want to install a matched pair?
Consider the Sonnet Fusion Flex J3i (also here at B&H). It is an empty enclosure, so you can choose your own drives. It will also hold a third SSD.

I would like to purchase a compatible 8tb drive for this, is there any update on what that product is, and a link to purchase it?
