1 TB SATA drive for entry servers
The HPE 655710-B21 is a 2.5 inch laptop hard drive with a 1 TB capacity and a 7200 RPM spindle speed. It connects through a SATA 6.0Gb/s interface and fits the small form factor bays found in many entry servers and external storage arrays. The drive is supplied new and carries the standard HP qualification process for ProLiant compatibility.
Thermals noise and power in normal use
Designed for workloads of 40 percent or less, the Midline drive runs at the 7200 RPM rating during typical backup and archival tasks. Acoustic output and power draw remain consistent with the SATA 6.0Gb/s specification for 2.5 inch devices. The 15.6 mm height allows installation in standard SFF slots without additional clearance concerns.
Behaviour under sustained load
Under continuous operation the drive maintains its rated spindle speed while serving sequential read or write streams for archival workloads. The qualification process verifies reliable performance in HP ProLiant servers during extended duty cycles. Workloads exceeding the 40 percent threshold are outside the intended design envelope for this Midline model.

Questions about this item
How do I install this 2.5-inch 15.6 mm SATA drive in a server bay, and which step is often missed?
Mount the drive in a 2.5-inch SFF bay using the correct screws, connect the SATA 6.0Gb/s data and power cables, then verify the controller detects 7200 RPM operation; the step often missed is enabling AHCI or RAID mode in BIOS before the OS loads.
What maintenance or replacement will this 1TB midline drive need later?
Plan replacement once the workload consistently exceeds the 40 percent duty-cycle rating for midline drives; monitor SMART reallocated-sector counts and replace the unit if they rise steadily.
What limit appears first when this 7200 RPM drive runs sustained workloads?
The 40 percent workload ceiling is the first limit; sustained writes beyond that level increase latency and reduce the drive's rated service life.
