About the 400-BKHH
The Dell 400-BKHH is a Dell 7.68TB NVMe PCIe Gen4 Read Intensive 2.5-inch Hot-Plug SSD providing 7680GB of enterprise solid-state storage across a NVMe PCIe Gen4 x4 (U.2 / U.3) interface in an enterprise 2.5-inch in Gen15/Gen16 hot-plug carrier format. Built with Samsung enterprise NAND flash memory, the 400-BKHH is rated for Read Intensive, 1 DWPD workloads, delivering low access latencies and consistent I/O throughput. In Dell's storage portfolio, 400-BKHH serves as a high-speed storage tier for transaction processing, database indexing, and virtualization clusters.
Compatibility
The 400-BKHH installs into 2.5-inch hot-plug drive bays across Dell enterprise servers including R750, R650, R760, R660. The 400-BKHH mounts inside a DXD9H (14G–16G) 2.5-inch hot-plug drive carrier with status and activity LEDs. Drive communication for the 400-BKHH requires a compatible storage controller (direct NVMe PCIe backplane cabling) supporting NVMe PCIe Gen4 x4 (U.2 / U.3) protocol communication. Part 400-BKHH 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 0M8F5R, 7680GB capacity, NVMe PCIe Gen4 x4 (U.2 / U.3) branding, and Samsung factory model MZ-QL27T600. In iDRAC under Physical Disks, the 400-BKHH 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-BKHH, 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-BKHH to verify interface stability without bus reset events. Confirm that the 2.5-inch drive tray on the 400-BKHH is straight with an intact release latch mechanism.
