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.
