The Ultrastar DC SN861 3.84TB pairs PCIe Gen 5 throughput with enterprise PLP capacitors, targeting high-DWPD workloads in dense NVMe storage builds.
Enterprise mixed-use and read-intensive workloads — including transactional databases, AI inference data, virtualisation, hyperconverged storage, and analytics. Endurance is rated for continuous operation, not consumer-style burst use.
Most enterprise SSDs ship in vendor-branded variants tied to a server QVL.
