PC Perspective checked out the Intel Expands Optane SSD 905P HHHL AIC and U.2 to 1.5TB Capacity + Quick Look A quote from the article:

Intel just sent over a note that they have officially launched the 1.5TB capacity for the Optane SSD 905P (for both HHHL and U.2 form factors). Wed been expecting this for a while now, considering we had tested a full system incorporating the U.2 version of this very capacity two months ago. That system has now been given away, but I borrowed the SSD while Ken was tearing down the system for his review. With the product now officially launched, I thought it appropriate to take a quick look at this higher capacity part, both inside and out.

7 packages on one side of a single PCB. This is unexpected for a U.2 SSD since there is usually some sort of folded-over PCB sandwich, which doubles the available area for packages. Odd finding a single PCB here given the large 1.5TB capacity combined with XPoint dies only holding 16GB each.
