About the 400-BKHK
The Dell 400-BKHK is a Dell 3.2TB NVMe Gen4 Mixed Use 2.5in Hot-Plug SSD providing 3200GB of enterprise solid-state storage across a NVMe PCIe Gen4 U.2/U.3 interface in an enterprise SFF 2.5in format. Built with Kioxia enterprise NAND flash memory, the 400-BKHK is rated for MU (3 DWPD) workloads, delivering low access latencies and consistent I/O throughput. In Dell's storage portfolio, 400-BKHK serves as a high-speed storage tier for transaction processing, database indexing, and virtualization clusters.
Compatibility
The 400-BKHK installs into 2.5-inch hot-plug drive bays across Dell enterprise servers including R750, R650, R760, R660. The 400-BKHK mounts inside a DXD9H (14G–16G) 2.5-inch hot-plug drive carrier with status and activity LEDs. Drive communication for the 400-BKHK requires a compatible storage controller (direct NVMe PCIe backplane cabling) supporting NVMe PCIe Gen4 U.2/U.3 protocol communication. Part 400-BKHK is designed for 2.5-inch backplanes and is not compatible with 3.5-inch bays without an approved adapter bracket.
How to identify a genuine unit
Authentic Dell enterprise solid-state drives display a silver-and-white label showing DP/N 0F51N8, 3200GB capacity, NVMe PCIe Gen4 U.2/U.3 branding, and Kioxia factory model KCD61EUL3T20. In iDRAC under Physical Disks, the 400-BKHK enumerates with certified Dell firmware revision, negotiated bus link speed, temperature telemetry, and real-time wear-out percentage monitoring.
Buying used
When sourcing a pre-owned 400-BKHK, check SMART endurance indicators using Dell OpenManage or smartctl to confirm remaining flash life, total bytes written, and zero reallocated flash blocks. Run a short and extended drive self-test on the 400-BKHK to verify interface stability without bus reset events. Confirm that the 2.5-inch drive tray on the 400-BKHK is straight with an intact release latch mechanism.
