HPE 804631-B21 1.60 TB 2.5" SATA internal hard drive

Server-Ready Mixed-Use SSD

The HPE 804631-B21 is a 1.60 TB solid-state drive built for server environments. It uses a 2.5-inch form factor and connects through a SATA interface running at 600 MB/s. The drive is rated for mixed-use workloads, balancing read and write endurance. It suits administrators who need reliable flash storage inside supported server platforms.

Replacing Spinning Disks in Server Bays

This SSD replaces 2.5-inch mechanical drives that limit random I/O and increase latency. The jump is worth it when applications demand consistent throughput for databases, virtualization or logging. It fits the same SFF bays and uses the same SATA cabling, so no backplane change is required. Buyers who need higher capacity than 1.60 TB or a different endurance class should look elsewhere.

Steady Performance Under Continuous Load

Mixed-use firmware keeps write latency stable during sustained operations rather than only in short bursts. The SATA 600 link delivers predictable bandwidth for long-running jobs such as database replays or log ingestion. Thermal throttling is managed within the server chassis airflow design. Workloads that exceed the rated write endurance will see reduced lifespan.
