1 TB SATA drive for G8/9 servers

This 1 TB SATA drive fits HP G8 and G9 systems using the 2.5 inch form factor. It spins at 7.2K RPM and connects through a 6 Gbps SATA interface. The part numbers 655710-B21 and 656108-001 identify the compatible models for straightforward replacement.

Thermals noise and power in normal use

Mechanical operation at 7.2K RPM produces typical hard-drive acoustics and heat output for a 2.5 inch SATA drive. Power draw follows standard SATA specifications during read and write workloads. No active cooling beyond normal chassis airflow is required.

Packing variation and compatibility

Retail or OEM packing may vary, so the drive may arrive in a plain anti-static bag or a branded box. No mounting brackets, cables or software utilities are included with the bare drive. Compatibility is limited to systems that accept 2.5 inch SATA drives with the listed part numbers.

Questions about this item

How do I install the 2.5 inch SATA drive in a G8 or G9 server tray?

Slide the drive into the 2.5 inch bay until the SATA connector seats firmly, then secure the tray latch; the step often missed is not clicking the latch fully home.

What part of this 1 TB drive is most likely to need replacement first?

The mechanical spindle and actuator assembly will wear before the electronics; plan to replace the whole drive once SMART data shows rising reallocated-sector counts.

What performance limit appears first during sustained writes on this 7.2K rpm SATA drive?

The 7.2K rpm rotational speed caps sustained throughput, so the drive hits its sequential-write ceiling before the 6 Gbps SATA link saturates.
