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). We'd 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.
7 more packages along with the now standard XPoint controller. No DRAM necessary because, well, XPoint can easily pull double duty in that respect. Alright, so we have 1.5TB spread across only 14 packages. Throughout every Intel SSD we have ever laid our hands on for review, we've never seen *any* product (NAND or 3D XPoint) stack more than 4 dies per package. Had Intel stuck with that limit here, we would only have a maximum raw media capacity of 896GB. This is a 1.5TB SSD, so the only possible answer here is that we apparently have the first 8-die-per-package SSD to come out of Intel.
