500 GB 2.5" SATA 6.0Gb/s drive

This 500 GB internal hard drive uses a 2.5 inch form factor and a SATA 6.0Gb/s interface. It spins at 7200 RPM and is designed for HP ProLiant Gen8 servers. The drive measures 15.75mm in height, 75.7mm in width and 118.62mm in length.

Server storage and archival use

The drive suits entry server and external storage environments with low workloads of 40% or less. It is built for backups, archival applications and non-mission critical tasks where economical reliability is the priority. Buyers who need higher workload endurance or mission-critical reliability should look elsewhere.

15.75mm drive height

The physical height of 15.75mm determines whether this drive fits the target drive bay. Verify the server or enclosure specification for 2.5 inch bays that accept this exact height before purchase.

Questions about this item

Will the 2.5-inch form factor with 15.75 mm height fit my ProLiant Gen8 drive bay?

Yes, the 2.5-inch drive measures 15.75 mm tall, 75.7 mm wide and 118.62 mm long, matching the standard small-form-factor bay used in ProLiant Gen8 servers.

Does the 7-pin SATA connector plug straight into the server backplane, or do I need a caddy?

The drive uses a standard 7-pin SATA interface; most ProLiant Gen8 bays accept it directly, but some configurations require the HP drive caddy — check your chassis manual before installing.

How often should I expect to replace a 7200 RPM drive running 40 % workload in a backup array?

HP rates Midline SATA drives for workloads of 40 % or less; under that duty cycle the 500 GB unit typically reaches its design life before mechanical wear requires replacement.
