I believe that's the below linked version (2TB w/heatsink is currently ~$429 on official Western Digital store).
Probably the best of the best in benchmarks:
WD_BLACK™ SN850 NVMe™ SSD PCIe® Gen4 for PC or Laptop | Western Digital | Western Digital Store
Long load times are obsolete with next-gen PCIe® Gen4 technology. Arm your system with RGB lighting, an optional heatsink model, and up to 2TB1 capacity.
