SanDisk SN655 61.44TB WUS5EC1C1ESP7Y3 ISE U.3 Enterprise NVMe SSD

Built for Large-Scale Enterprise Storage

The SANDISK SN655 NVMe™ SSD delivers 61.44TB of enterprise flash storage in a standard 2.5-inch U.3 15mm form factor, giving cloud and server providers the capacity to consolidate more data per drive. Built for read-intensive, data-heavy workloads, it combines PCIe Gen4, NVMe 1.4b, and Sandisk BiCS5 3D TLC NAND to provide the throughput and density required for modern storage infrastructure.

High-Capacity Performance for Data-Driven Workloads

Large datasets demand more than raw capacity. The SN655 reaches 4,300MB/s sequential read, 3,150MB/s sequential write, and up to 890K random read IOPS, allowing storage platforms to serve large volumes of unstructured data with consistently low latency. This makes it well suited to analytics, cloud services, and machine learning environments where reducing time-to-insight is a priority.

Enterprise Reliability as Standard

Designed for always-on deployments, the SN655 features dual-port redundancy and failover capability to maintain drive availability in multi-path environments. Power loss protection, end-to-end data path protection, and support for variable sector sizes help safeguard data integrity, while a projected 2.5 million hour MTBF, 1.0 DW/D endurance, and 5-year limited warranty provide the reliability expected in enterprise data centres.

Optimised for Cloud and Scale-Out Infrastructure

Powered by Sandisk's next-generation NVMe 1.4b controller, the SN655 is optimised for cloud and scale-out storage architectures where predictable QoS is critical. Support for both U.2 and U.3 backplanes simplifies deployment into existing server infrastructure, while the drive's high capacity enables providers to increase storage density and improve GB-per-watt efficiency as AI, machine learning, and big data workloads continue to grow.

Ready for Modern Data Centres

From cloud storage and hyperscale deployments to AI and machine learning infrastructure, the SN655 combines enterprise features with broad platform compatibility. Its standard U.3 15mm form factor, support for U.2 and U.3 backplanes, and compatibility with Windows, Windows Server, and Linux allow it to slot into existing server environments while delivering the capacity and read performance required by today's largest datasets.
