HP StorageWorks MSA2 750GB drive

The HP StorageWorks MSA2 AJ739A is a 750GB 3.5-inch internal hard drive spinning at 7200 RPM with a dual-port SATA 3.0Gb/s interface. It is supplied new in retail packaging and carries a three-year limited warranty. The drive is designed as an HP Qualified Option for efficient data storage management.

Dual-port SATA for redundant arrays

This drive suits administrators maintaining or expanding HP MSA2 storage arrays that require dual-port SATA connectivity for path redundancy. It is not for builders who need a single-port desktop drive, users who require the higher throughput of a 6Gb/s SATA link, or anyone looking for solid-state speed.

Dual-port SATA 3.0Gb/s interface

The defining specification is the dual-port SATA 3.0Gb/s interface, which enables multipath I/O in compatible HP enclosures. Verify that your controller and backplane support dual-port operation before purchase.

Questions about this item

How much noise and heat does the 7200 RPM dual-port SATA 3.0Gb/s drive produce when running all day?

The 7200 RPM spindle and dual-port SATA 3.0Gb/s interface generate typical mechanical-drive noise and warmth; mount it in a 3.5-inch bay with normal chassis airflow to keep temperatures in check.

What must my system already have to use the dual-port SATA 3.0Gb/s interface on this 3.5-inch drive?

A backplane or controller with two SATA 3.0Gb/s ports and a standard 3.5-inch hot-swap tray is required for both data paths and mechanical mounting.

Will the dual-port SATA 3.0Gb/s drive work in an older enclosure that only provides a single SATA 3.0Gb/s connection?

Yes — the drive will operate on a single SATA 3.0Gb/s port, but the second port remains unused so multipath redundancy is not available.
