Capacity and fit

The Seagate Barracuda XT ST4000DX000 is a 4 TB internal hard drive built in the 3.5 inch form factor. It suits desktop owners who want a large mechanical volume for bulk storage. Buyers needing solid-state speeds or a 2.5 inch laptop drive should look elsewhere.

SATA 600 interface limits

The drive connects through a SATA 600 interface with a 600 MB/s theoretical ceiling. Real-world throughput is lower and varies with workload, cable quality and controller implementation. Systems restricted to SATA 300 will still work but at the slower rate.

Pre-install checks

Confirm your chassis has a free 3.5 inch bay and that the motherboard offers an unused SATA port. Verify the power supply provides a spare SATA power connector. Ensure the operating system can address a 4 TB volume with the chosen partition scheme.

Questions about this item

Is the 4 TB Barracuda XT the right capacity for a desktop that stores large media libraries?

The 4 TB capacity suits desktop builds that keep video, photo and game collections on a single internal drive.

What does the SATA 600 label tell me about real-world throughput?

SATA 600 caps the interface at 6 Gbit/s, so sustained transfer rates will not exceed that ceiling in any system.

Will this 3.5-inch SATA drive fit a standard desktop drive bay and connect to a SATA 600 port?

Yes, the 3.5-inch form factor matches standard desktop bays and the SATA interface works with any SATA 600 controller.
