HP Enterprise 300GB SAS Drive
The HP Enterprise 492620-B21 is a 300GB 2.5-inch internal hard drive spinning at 10000 RPM with a SAS 3Gb/s interface. It is built for server environments where consistent throughput and enterprise-grade reliability are required. The 4ms average seek time supports rapid data access in demanding workloads. This new drive arrives in retail or OEM packaging.
Server Builders Needing 10K SAS Storage
System integrators maintaining or expanding 2.5-inch SAS storage arrays will find this drive a direct fit for compatible HP server bays and controllers. It suits applications that prioritize sustained I/O over maximum capacity. Buyers who need a larger capacity or a faster SAS interface should look at other models. Laptop users and desktop builders without SAS infrastructure cannot use this drive.
SAS 3Gb/s Interface Decides Compatibility
The single specification that determines fit is the SAS 3Gb/s interface; the system backplane and controller must support this exact protocol. A 10000 RPM spindle speed and 300GB capacity follow from the interface choice. Verify the host hardware lists SAS 3Gb/s before purchase.

Questions about this item
How is the 2.5" SAS drive installed in a server bay, and what step is often missed?
Slide the 2.5" SFF unit into the hot-swap tray until the SAS 3Gb/s connector seats firmly; the step often missed is securing the tray latch so vibration cannot unseat the drive.
What maintenance or replacement will the 10000 RPM drive need later?
Mechanical wear on the 10000 RPM spindle and actuator means the drive itself is the only field-replaceable part; plan a spare 300GB unit for rebuilds.
What limit appears first on the SAS 3Gb/s interface under sustained write loads?
The 3Gb/s SAS link caps sustained throughput before the 10000 RPM media saturates, so sequential writes plateau at the interface ceiling.
