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.

Questions about this item
How do the 1000 MB/s read and 510 MB/s write speeds translate to daily server workloads?
The 1000 MB/s sequential read and 510 MB/s sequential write deliver fast bulk data transfer, while 70000 random read IOPS and 51000 random write IOPS accelerate database and virtualization tasks.
What does the SAS 12Gb/s interface mean for throughput limits?
SAS 12Gb/s supports up to 12 Gb/s per lane; the drive reaches 1000 MB/s read and 510 MB/s write, so the interface does not bottleneck those speeds.
Will this 2.5 inch drive fit my server bay and caddy?
The drive measures 2.5 inches wide, 5.5 inches high, 7.3 inches deep and weighs 15.87 oz, matching standard 2.5 inch enterprise hot-plug bays.
