HP 300 GB 15K SAS Drive

This HP 627117-B21 is a 300 GB enterprise hard drive spinning at 15000 RPM with a SAS 6Gb/s interface in a 2.5 inch form factor. It is built for server environments that demand high transaction rates and consistent low latency.

Suited for 15K SAS server bays

The drive fits 2.5 inch hot-swap bays that support SAS 6Gb/s signalling and can supply the power required for 15000 RPM operation. It is not for systems lacking a SAS controller, for ultra-thin laptop chassis limited to 7 mm height, or for workloads that need more than 300 GB on a single spindle.

15000 RPM spindle speed

The 15000 RPM rotation speed is the specification that determines whether this drive meets the random I/O performance target of the deployment. Confirm the host backplane and controller support SAS 6Gb/s before purchase.

Questions about this item

Does the HP 627117-B21 ship with a mounting bracket or caddy, or must that be sourced separately?

The drive is supplied in retail or OEM packaging that may vary; a mounting bracket or caddy is not included and must be purchased separately for your server chassis.

Why choose the 300GB 15000 RPM SAS model instead of a lower-speed or higher-capacity alternative?

The 300GB capacity paired with 15000 RPM SAS 6Gb/s targets transaction-heavy server workloads where low latency and consistent IOPS matter more than raw capacity.

What does the 15000 RPM speed mean for database or virtualization workloads on this 2.5" SAS drive?

The 15000 RPM spindle reduces average rotational latency, delivering faster response times for random read and write patterns typical in database and virtualization environments.
