HP 779164-B21 2.5" 200GB SAS 12Gb/s enterprise SSD

HP 200GB SAS 12Gb/s Enterprise SSD

The HP 779164-B21 is a 2.5-inch solid-state drive built for server and storage arrays that require consistent, low-latency performance. Its mainstream endurance rating suits mixed read-write workloads such as virtualisation, databases and email servers. The drive connects through a dual-port SAS interface, simplifying integration into existing HP ProLiant and compatible enterprise chassis. It targets IT teams who need reliable flash storage without the cost of write-intensive models.

SAS 12Gb/s interface determines compatibility

The drive communicates over a 12Gb/s SAS link, so the backplane, controller or HBA must support that speed to achieve quoted throughput. A 6Gb/s SAS connection will work but limits sequential reads to roughly half the rated 1000 MBps and writes to half the rated 510 MBps. The physical 2.5-inch form factor fits standard hot-plug carriers, yet the electrical interface is the decisive factor when verifying fit for a specific server generation.

200GB capacity with mainstream endurance headroom

At 200GB the drive holds operating-system volumes, hypervisor boot images or small database indexes with room for over-provisioning that sustains steady write performance. Random-write IOPS reach 51,000, sufficient for transactional workloads, while the 2,000,000-hour MTBF and 9W active power draw support continuous operation in 0°C to 60°C environments. Workloads that demand sustained heavy writes or multi-terabyte datasets will exceed the usable space and endurance budget of this model.
