Desktop storage for servers and workstations

The Seagate BarraCuda 7200.10 ST3750640AS is a 750GB 3.5 inch internal hard drive that spins at 7200 RPM with a 16MB cache. It uses perpendicular recording technology to reach this capacity in the standard form factor and is described by the manufacturer as ideal for server environments.

Check your motherboard and cabling before ordering

The drive connects through a SATA 3.0Gb/s interface and requires a matching port and data cable on the host system. Verify that the BIOS or controller can address a 750GB volume and that the operating system can initialise a drive of this size without additional drivers.

Bare drive construction

Supplied without brackets, screws or cables, the unit is intended for installation into a 3.5 inch bay using standard mounting points. The SoftSonic motor keeps acoustic output low while Enhanced G-Force Protection helps defend the mechanism against handling shocks during integration.
