800 GB SAS enterprise SSD
This 2.5 inch solid-state drive uses MLC memory and a SAS 6Gb/s interface to deliver 800 GB of capacity. It is built for server environments that require consistent write endurance and reliability. The refurbished condition means the unit has been tested and restored to working order. It suits administrators who need proven enterprise storage without new-unit lead times.
Hot-plug tray installation and firmware alignment
The drive fits standard 2.5 inch hot-plug trays found in HP ProLiant and compatible servers, so physical insertion takes seconds. Most issues arise when the controller firmware or backplane expander firmware is outdated, causing the drive to negotiate at a lower link speed or to be invisible to the RAID BIOS. Applying the latest system firmware before installation avoids these detection problems. Cable routing in dense chassis can also pinch the SAS connectors if care is not taken.
Steady write latency under sustained load
MLC architecture provides predictable latency during long sequential write workloads such as database logging or virtual machine image streaming. The SAS 6Gb/s link maintains throughput without the sharp throttling seen in consumer drives after their cache fills. Thermal throttling is minimal in typical server airflow, so performance remains stable across extended duty cycles. Workloads that exceed the rated write endurance will eventually wear the cells, so capacity planning should account for total bytes written.

Fragen zu diesem Artikel
How can I verify the 800GB SAS drive is working correctly after installation?
Check the server BIOS or RAID controller to confirm the 800GB capacity is detected and the SAS 6Gb/s link speed is negotiated.
What is included with the refurbished 632639-001-R unit and what must I source separately?
The package contains the 2.5" MLC SSD only; a compatible SAS backplane, caddy, cables and RAID controller are not included.
Which capacity version of this HP enterprise SSD should I select for a 2.5" SAS bay?
This specific model 632639-001-R is offered in a single 800GB capacity with MLC memory and a SAS 6Gb/s interface.
