200 GB SAS solid-state drive

The HP 690819-B21 is a 2.5-inch solid-state drive built for enterprise notebook and blade bays. It uses single-level cell NAND and a SAS interface to deliver faster read speeds and lower power draw than mechanical drives. The 200 GB capacity suits local boot or caching workloads. Hot-swap support allows replacement without shutting down the host.

Suits extreme-environment boot

This drive targets systems that need reliable local boot or read-intensive caching in harsh conditions. Buyers who need larger capacities for bulk data storage should consider other options. Workloads that demand sustained high write throughput may exceed the design focus of this model. It is not intended for consumer laptop upgrades lacking SAS backplanes.

SAS 6 Gb/s interface

The drive connects through a SAS 6 Gb/s link, which determines controller and backplane compatibility. Verify that the host system provides a SAS 6 Gb/s port and 2.5-inch hot-swap bay before purchase. The interface speed also sets the maximum sequential read bandwidth available to the operating system. No other interface is supported.

Questions about this item

Should I choose the 200 GB version or a larger capacity for my ProLiant blade?

The 200 GB size is the only capacity offered for this 690819-B21 model. If you need more space, you would need a different drive part number.

What does the 6 Gb/s SAS rating deliver in a real server?

The 6 Gb/s SAS link provides fast read speeds and low latency for local boot or extreme environments, limited by the drive's internal NAND flash performance.

How does the SAS interface limit performance in practice?

The SAS 6 Gb/s interface caps the maximum burst transfer rate at 6 Gb/s; sustained throughput depends on the single-level cell NAND flash inside the drive.
