This is an HP-branded 1TB PCIe Gen4x4 NVMe M.2 solid-state drive designated for HP's ProLiant Gen10 server line, sold as a genuine HP server storage option rather than a generic retail SSD. Server-specific drives like this are validated and firmware-tuned by HP for use in its own server chassis, and are typically bought to expand or replace storage in an existing HP Gen10 server rather than for use in a regular desktop PC. The catalog listing doesn't give further detail on endurance rating or exact read/write speeds — buyers should confirm compatibility with their specific server model and backplane before ordering.
