Enterprise write-tiering drive

The Intel Optane DC P5800X 400GB 2.5" U.2 drive targets data-centre caching and hot-data tiering. Its 3D XPoint media delivers consistent low latency for write-intensive workloads. The 15mm z-height fits standard U.2 bays in rack servers. It is not for bulk-capacity storage tiers where cost per gigabyte dominates.

PCIe 4.0 x4 throughput ceiling

The PCIe 4.0 x4 link caps sequential reads at 7200 MBps and writes at 4800 MBps. Active power draw reaches 14W, so chassis airflow must handle the thermal load. The interface does not scale beyond four lanes, limiting peak bandwidth in multi-drive arrays. Builders needing higher single-stream throughput cannot meet it with this interface generation.

100 DWPD endurance rating

A 100 drive-writes-per-day rating over five years yields 73,000 TBW total endurance. This single figure determines whether the drive survives sustained write caching or logging workloads. Lower-endurance alternatives will wear out prematurely under the same duty cycle. AES 256-bit encryption and end-to-end data protection are included.

Questions about this item

Should I pick the 400 GB U.2 model or a different capacity for my write-heavy workload?

The 400 GB U.2 model delivers 100 DWPD and 73,000 TBW, making it suitable for write-intensive applications that need consistent endurance.

What does the 7,200 MB/s sequential read figure mean once the drive is installed in a server?

That peak read speed is reached over the PCIe 4.0 x4 link when the controller can sustain large-block transfers; real-world throughput depends on queue depth, CPU overhead and thermal limits.

How does the PCIe 4.0 x4 NVMe interface cap performance in practice?

The x4 lane width limits maximum theoretical bandwidth to roughly 8 GB/s, so the drive’s 7,200 MB/s read and 4,800 MB/s write ratings operate within that ceiling.
