Product identity

The Seagate BarraCuda ES.2 ST3750630SS is a refurbished 750GB 3.5" internal hard drive with a SAS 3Gb/s interface, 7200 RPM spindle speed and 16MB cache. It is supplied as a bare drive for desktop or server installations that use the SAS protocol.

Fit and alternatives

This drive suits systems that need a 3.5" SAS drive at 750GB capacity and 7200 RPM performance. Buyers whose controller or backplane requires a different interface or who need a larger capacity should select another model.

Deciding specification

The SAS 3Gb/s interface is the single specification that determines whether this drive will work in your system; the controller and backplane must support SAS at that signalling rate.

Questions about this item

How do I install this 3.5" SAS drive and what step is often missed?

Mount the drive in a 3.5" bay, attach both the SAS data cable and the 15-pin SAS power connector, then ensure the host controller or backplane is configured for 3 Gb/s SAS operation so the drive is recognised.

What maintenance or replacement will this refurbished BarraCuda ES.2 need later?

As a mechanical drive with moving platters at 7200 RPM, plan to replace it once SMART attributes such as reallocated sectors or seek errors begin to rise, indicating wear.

What limit appears first when this 750GB drive runs sustained workloads?

The 3 Gb/s SAS interface sets the maximum sustained transfer ceiling, so throughput plateaus at the bus speed before the 16 MB cache or spindle speed can deliver more.
