This is a 7.68TB enterprise-grade U.3 NVMe solid-state drive from Synology, built for use in Synology's enterprise NAS and all-flash storage systems rather than desktop PCs. The 'dual-port' design lets the drive be accessed via two separate NVMe paths simultaneously — used in high-availability storage clusters so a drive keeps serving data even if one connection path or controller fails. U.3 is an enterprise SSD form factor/interface built for hot-swappable, high-throughput storage arrays. At 7.68TB, it's aimed at businesses needing large-capacity, high-performance, always-on flash storage for virtualization, databases, or file services, backed by a 5-year manufacturer warranty reflecting its enterprise duty-cycle rating.
