Server Storage Drive

The HP Midline 507610-B21 is a 500 GB 2.5 inch internal hard drive spinning at 7200 RPM with a SAS 6Gb/s interface. It is built for enterprise server environments that demand hot-plug capability and consistent reliability. The 9.5 mm height fits standard 2.5 inch server drive bays. New condition ensures full manufacturer specification life from installation.

Suited For And Not For

This drive suits administrators expanding or repairing compatible HP ProLiant BL465c G6, BL685c G6 and DL320 G6 server blades or rack units. It is not suited for systems lacking a SAS backplane or hot-plug cage. Buyers needing larger capacities or solid-state speeds should evaluate alternative drives. The retail packaging may vary between retail and OEM presentation.

Deciding Specification

The SAS 6Gb/s interface is the single specification that determines whether this drive will function in the target server. A SAS controller and compatible backplane are mandatory for operation. Without SAS infrastructure the drive cannot be used regardless of capacity or spindle speed.

Questions about this item

How much heat and noise does the 7200 RPM SAS drive add when it runs 24/7 in a server bay?

The Midline 500GB unit spins at 7200 RPM with a 9.5 mm height, 69.75 mm width and 100.3 mm length; HP classes it for 24x7 server use, so heat and acoustic output stay within typical enterprise 2.5" SAS limits.

What controller or backplane must I already have to connect the SAS 6Gb/s interface?

A host bus adapter, RAID controller or server backplane with a SAS 6Gb/s connector is required; the drive uses the standard SAS interface and hot-plug capability listed in the specifications.

Will the 507610-B21 work in the ProLiant DL320 G6 and BL465c G6 blades I still run?

Yes — the drive is validated for HP ProLiant DL320 G6, BL465c G6 and BL685c G6 servers, and its 2.5" SAS form factor fits the same drive bays used by those older models.
