800GB SAS 12Gb/s enterprise SSD

The HP 779172-B21 is a new 2.5-inch solid-state drive built for enterprise servers and storage arrays. It connects through a 12Gb/s SAS interface and provides 800GB of capacity for mixed-use workloads. Sequential reads reach up to 1000 MBps while writes reach up to 565 MBps. Random 4KB performance delivers up to 66,000 read IOPS and 64,000 write IOPS.

Suits mixed read-write server workloads

This drive fits administrators who need a mainstream SAS SSD for databases, virtualization or general application storage in compatible 2.5-inch bays. It is not for systems that require a different physical form factor or interface protocol. Buyers who need higher endurance for write-intensive tasks should evaluate drives specified for that workload class.

SAS 12Gb/s interface decides compatibility

The single specification that determines whether this part works is the SAS 12Gb/s interface; the host controller and backplane must support this exact link speed and protocol. Without a matching SAS 12Gb/s connection the drive cannot operate at its rated performance or be recognised by the system.

Questions sur cet article

How do I install the HP 779172-B21 into a 2.5-inch SAS hot-swap bay, and what step do people often miss?

Slide the drive into the bay until the SAS connector seats firmly; the step people miss is pressing the release lever fully home so the drive locks and the controller detects the 12Gb/s link.

What maintenance or replacement will the 800GB SAS SSD need later?

Enterprise SSDs have no moving parts to service; replacement is only required when the drive reaches its write-endurance limit or a SMART alert flags a media error.

What limit appears first on the 779172-B21 during sustained write workloads?

The max sequential write of 565 MBps is the first ceiling you hit; once the controller saturates at that throughput, latency rises and the drive cannot accept data faster.
