400 GB NVMe PCIe drive for servers
The HPE 764904-B21 is a 400 GB NVMe PCIe solid-state drive built in a 2.5-inch internal form factor. It is designed for server environments that require fast read-intensive storage on a PCI Express interface. The drive suits administrators adding high-speed capacity to compatible HPE platforms.
Thermals noise and power in normal use
As a solid-state device with no moving parts, the drive operates silently during typical read-intensive workloads. Power draw remains low compared with mechanical disks, and the compact 2.5-inch package fits standard server bays without additional cooling requirements beyond normal chassis airflow.
Behaviour under sustained load
The NVMe PCIe interface maintains consistent throughput during extended read-heavy operations such as database queries or virtualisation hosting. Write endurance is optimised for read-intensive duty cycles, so workloads dominated by large sequential writes may exceed the intended usage profile.

Questions about this item
How do I install the 764904-B21 into a server and what step is often missed?
Insert the 2.5" drive into a PCIe-capable SFF bay, secure it with the tray screws, and ensure the system BIOS is set to NVMe boot mode so the drive is recognised on first power-up.
What maintenance or replacement will the 400 GB NVMe drive need over its service life?
The read-intensive SSD has no moving parts and requires no scheduled maintenance; replacement is only needed if the drive reaches its write-endurance limit or a firmware update cannot resolve a detected error.
What limit appears first when the drive runs sustained workloads in a server?
Under continuous write-heavy loads the NAND write-endurance budget will be consumed before thermal throttling or interface bandwidth becomes a bottleneck.
