Product information

Description

The Western Digital Ultrastar DC SN655 NVMe SSD is a 3.84 TB U.3 form-factor drive designed for cloud and server environments that require high-capacity, low-latency storage. Built on PCIe 4.0 NVMe technology with Western Digital BiCS5 TLC 3D NAND and a next-generation NVMe 1.4b controller, the drive targets read-intensive, data-intensive applications and scale-out workloads while offering enterprise-grade reliability features.

Advantages

The SN655 provides dual-port redundancy with failover, end-to-end data protection and power-loss protection, plus support for U.2 and U.3 backplanes. With projected 2.5M MTBF, a 1.0 drive writes per day (DW/D) endurance class and a 5-year limited warranty, it delivers consistent QoS and high throughput (up to 6800 MB/s read, 2600 MB/s write) suitable for large unstructured datasets and machine-learning tasks.

Suitable for

Cloud and hyperscale server storage
Scale-out architectures and distributed file systems
Big data analytics and data lakes
