HP Enterprise 146GB SAS Drive

The HP Enterprise 507125-B21-R is a 146GB 2.5" SFF internal hard drive spinning at 10000 RPM with a SAS 6Gb/s interface. It is built for enterprise servers and storage arrays that require high-speed block access. The refurbished unit carries the manufacturer's original specifications for reliability and performance.

Suits SAS-Only Bays

This drive fits 2.5" SAS drive bays in compatible HP ProLiant servers and external enclosures. It is not suitable for systems that lack a SAS backplane or controller. Laptop users and desktop builders without enterprise SAS infrastructure should look elsewhere.

10000 RPM Spindle Speed

The 10000 RPM spindle speed delivers an average seek time of 4ms for rapid transactional workloads. This rotational speed is the primary determinant of the drive's IOPS capability and latency profile. Verify that your controller and cooling can support this performance tier before purchase.

Questions about this item

Does the 2.5" SFF form factor fit a standard laptop drive bay?

The 2.5" SFF form factor matches the standard 2.5-inch laptop drive bay, so it slides into the same mounting frame used by other 2.5-inch drives.

How is the SAS 6Gb/s drive installed, and what step is often missed?

Connect the drive to the SAS backplane or controller using the SAS data and power connector; the step often missed is securing the drive with the caddy screws so the connector cannot work loose.

What maintenance or replacement will the 10000 RPM SAS drive need later?

As a mechanical drive, it may eventually require replacement if bearing noise increases or SMART reallocated sectors rise; no scheduled maintenance is needed beyond monitoring health via the RAID controller.
