HP 300 GB 15 000 RPM SAS 6 Gb/s 2.5" drive

This HP 627117-S21 is a 300 GB 2.5-inch internal hard drive spinning at 15 000 RPM with a SAS 6 Gb/s interface. It is built for enterprise server and storage arrays that demand high transaction rates and consistent low latency. The drive arrives new in original or OEM packaging.

Suits servers needing fast SAS storage.

The 15 000 RPM spindle speed and SAS interface target rack-mount servers, blade systems and direct-attached storage where sustained random I/O matters. Laptop or desktop builders should look elsewhere because the SAS connector and enterprise firmware require a compatible backplane and controller. Capacity-focused buyers wanting more terabytes per spindle should also consider other form factors.

15 000 RPM spindle speed decides fit

The single specification that determines whether this drive fits the workload is the 15 000 RPM rotational speed. It delivers the high IOPS and low access times needed for transaction-heavy databases, virtualization hosts and performance-critical applications. If the application can use that speed profile, the 300 GB capacity and 6 Gb/s SAS link complete the package.

Questions about this item

Will the 2.5" form factor fit my server drive bay without an adapter?

The 2.5" form factor matches standard 2.5" SAS hot-swap bays; no adapter is required if the bay accepts 2.5" drives.

How do I install the 627117-S21 and what step is often missed?

Slide the drive into the hot-swap tray until the SAS connector seats firmly; the step often missed is locking the tray lever to secure the drive.

When should I plan to replace the 300GB 15000 RPM SAS drive in a 24×7 server?

In continuous operation, schedule replacement after the manufacturer's rated MTBF interval or when SMART attributes show reallocated sectors.
