Cisco 800GB U.2 WD SN640 NVMe UCSB-NVMEM6-W800= | Enterprise SSD — UCSB-NVMEM6-W800=

Keep storage performance steady under sustained enterprise demand with the Cisco 800GB U.2 WD SN640 NVMe drive. Built around a 2.5-inch U.2 form factor, this SSD is designed for server environments where mixed workloads, frequent writes, and operational consistency matter more than raw capacity alone. The SN640 family is known for balancing performance and endurance, making it a practical fit for infrastructure teams that need flash storage they can trust in production. In dense virtualization hosts, database nodes, or application servers, predictable latency and write durability can matter as much as headline throughput. This drive is positioned for exactly that kind of workload profile. For procurement teams, the value is straightforward: a Cisco-qualified storage option that fits enterprise deployment standards and reduces the risk of mismatched components. For architects, it offers a storage tier that supports long service life without forcing compromises on performance behavior. That combination is what justifies the premium over commodity SSDs. Ideal For Primary flash storage in Cisco UCS servers Mixed read-write workloads in virtualization hosts Database and application tiers requiring endurance Enterprise storage refreshes needing Cisco-qualified SSDs Why This Product 1 Higher endurance than standard client SSDs 2 Enterprise U.2 fit for Cisco server bays 3 NVMe performance for production workloads 4 Better suited to write-heavy environments than low-end flash
