Samsung's 15.36TB 2.5" Enterprise SAS SSD each cost $10,000 each. So if you were to get four for 61.44TB of those, it'd cost you $40,000 for 60TB. Though by your mathematics, I'm a bit confused and I'm not sure if I'm misinterpreting; are you saying per GB an 850 EVO costs $3 per GB?
That's nowhere near close to the cost per GB on an 850 EVO
Per the 850 EVO 4TB MSRP, the per gigabyte cost is 37.4 cents or $0.374 per GB.
Where's all the meaningful information, it's really lacking. This seems like a press announcement of a product that won't be on the market for a long while and when it does appear, limited capacity perhaps. No real launch date, no information on the NAND used besides the fact it's provisioned by Micron (Is it Planar or 3D NAND, MLC or TLC, Die Density, Dies per Package/Package Density, Applicable Specs for Endurance), what controller, what performance it offers in each segment of use... it's very vague. Did they just want to claim a record of "we have the largest SSD", because that's really what it seems like to me. It may ship in early 2017 and I guess we'll have to wait to see.
EDIT: Sounds like it'd have to be using the Intel-Micron 32-layer 256Gbit MLC die that can run as 384Gbit TLC. Since it mentions a density increase over the competition (now invalid), I assume it's ran in TLC. I'm not sure how I feel about this really, Samsung has been shipping their 48-layer 256Gbit MLC dies for a while now in products and has moved to onto using a more reliable trap charge flash approach for endurance versus the traditional floating gate approach on this Micron NAND.
