HP 632494-B21-R 400GB SAS 2.5" enterprise SSD

HP 400GB SAS Enterprise SSD

The HP 632494-B21-R is a 2.5-inch enterprise solid-state drive with 400GB capacity. It uses SLC memory components and a SAS 6Gb/s interface. The drive is designed for server environments that demand consistent write endurance and low latency. This refurbished unit suits administrators replacing failed drives in existing arrays.

Compatibility checks before ordering

Verify that your server or storage controller supports SAS 6Gb/s connections and 2.5-inch drive bays. Confirm the backplane or caddy accepts the physical form factor without adapters. Check firmware revision requirements for the specific RAID or HBA model in use. Ensure the operating system or hypervisor includes drivers for SAS enterprise SSDs.

Sustained load behaviour

SLC memory provides stable write performance across extended workloads without the throttling seen in consumer drives. The SAS interface maintains consistent throughput during heavy random I/O patterns typical of database or virtualisation hosts. Endurance characteristics suit write-intensive applications running continuously. Thermal output remains predictable in multi-drive enclosures under sustained utilisation.
