The Western Digital 0TS2459 is a 7.68TB UltraStar DC SN655 solid state drive that fits a U.3 backplane and runs on PCIe Gen4 with NVMe 1.4. Using Western Digital BiCS5 3D TLC NAND and a proprietary controller, it reaches up to 6,800 MB/s in sequential reads and as many as 980,000 random read IOPS, which helps eliminate storage bottlenecks for transaction-heavy databases, virtual machines, and real-time analytics.
The drive is optimized for read-intensive enterprise work where steady throughput, low latency, and consistent quality of service are essential. A 1.0 drive write per day endurance rating still provides comfortable margin for log files and occasional batch writes while prioritizing fast access to large data sets.
Reliability is addressed at multiple levels. Dual-port support creates two independent PCIe paths, so an alternate path stays active if the primary path fails. End-to-end data path protection checks every bit from the host to the NAND, and built-in power loss protection secures data that is still in flight during an unexpected shutdown. With a projected 2.5 million hour mean time between failures, the SN655 is ready for round-the-clock duty in dense server racks and all-flash arrays.
Deployment is straightforward. The drive drops into any server or storage shelf that offers a U.3 interface and is recognized by current versions of Windows, Windows Server, and Linux without extra drivers. This makes it a practical choice for data centers that handle big data analytics, AI and machine learning workloads, content delivery networks, or hyperconverged infrastructure.
