## Long description

The Western Digital Ultrastar DC SN655 15.3TB U.3 PCIe 4.0 NVMe SSD is a high-capacity, enterprise-grade drive designed for cloud and server environments that require read-intensive, low-latency storage. Built on Western Digital BiCS5 TLC 3D NAND and a PCIe Gen4 NVMe 1.4b controller, the SN655 is available in the 2.5" U.3 form factor and supports U.2/U.3 backplanes, dual-port redundancy and failover, and power-loss protection. Typical use cases include large unstructured datasets, big data analytics, and machine learning workloads where consistent QoS, high IOPS, and increased capacity are required.
Advantages
The Ultrastar DC SN655 offers high capacity (15.3 TB), low-latency performance with up to 1.1M IOPS, and PCIe 4.0 bandwidth for faster data transfer (up to 6800 MB/s read, 3700 MB/s write). Enterprise features include dual-port redundancy and failover, end-to-end data protection, power-loss protection, a projected 2.5M MTBF, and data endurance ratings suitable for demanding server environments. The drive is compatible with standard 2.5" U.3/U.2 infrastructures and comes with a 5-year limited warranty.
Suitable for
Cloud and hyperscale server storage
Big data analytics and data lakes
Machine learning and artificial intelligence workloads
Read-intensive enterprise databases and scale-out applications
