I'm curious how endurance is handled in this case. Is there a wear level guarantee when provisioning it? I guess this is applicable to any consumable though this seems to be a pretty expensive one.
That’s part of the design of Optane (née 3DXpoint): it’s supposed to be lower latency than traditional SSD and higher durability. I don’t know enough about the how nor the details to say more, sorry.
This article from Anandtech [1] covers the SSD variant though which states:
The endurance rating for both capacities is 200 GB/day for the five-year warranty period. Given the small capacity of the drives, this works out to 1.7 or 3.4 drive writes per day, which is considerably higher than normal for consumer SSDs.
Optane is the brand name for Intel products that use 3D XPoint memory. Micron products that use 3D XPoint memory will be sold under Micron's QuantX trademark, if they ever ship. There's also a possibility that Micron could eventually start selling 3D XPoint memory to other SSD manufacturers, and the resulting products wouldn't bear either Optane or QuantX branding.
The more relevant comparison for endurance may be the enterprise Optane SSD DC P4800X, which was initially released with a 30 DWPD rating but has since been increased to 60 DWPD. Intel hasn't described what kind of error correction that drive is doing under the hood, but it's probably more robust than what the entry-level consumer Optane drives do, and possibly more robust than what the DIMMs can do within their latency budget.
