This is the Secure Erase (SE) model.
The 3.84TB UltraStar DC SN655 PCIe Gen4 NVMe 1.4 U.3 Internal Solid State Drive provides the trusted performance reliability, and security demanded by enterprise environments. The Ultrastar DC SN655 NVMe expands the Ultrastar SN65x family with a dual-port drive,
expanded encryption capabilities, and added performance. It continues to be the ideal solution for cloud and server providers who need high-capacity, cost-optimized, read-intensive performance for their data-intensive applications.
With dual-port redundancy and failover capability, end-to-end data protection and additional enterprise features, the SN655 helps ensure your data is secure and available when needed. With high-capacity, low-latency performance reaching up to 1.1M IOPs, storage providers are efficiently able to increase capacity for modern applications processing large unstructured datasets for analytics, artificial intelligence, or machine learning. With these workloads growing to gigabytes and even petabytes, storage-optimized Ultrastar NVMe is reducing time-to-insights of big data and enabling efficient machine learning.
The Ultrastar DC SN655 NVMe includes the next generation Western Digital NVMe 1.4b controller with PCIe Generation 4.0 interface and Western Digital BiCS5 TLC 3D NAND. NVMe provides hosts low-latency access to direct attached NVMe solid state drives or to NVMe-oF storage arrays. BiCS5 TLC 3D NAND is the next generation of 3D NAND driving higher bit densities per mm for higher capacities than prior generations. Equipped with the latest PCIe Generation 4.0, the SN655 enables performance at scale for increasingly larger application workloads. Designed and built for the standard 2.5” storage infrastructure, the SN655 includes support for U.2 and U.3 backplanes. And
with enterprise grade power loss protection, 2.5M MTBF (projected) and 1.0 DW/D with a 5 year limited warranty, cloud and IT managers can deploy and scale their datacenters confidently.
