1 TB BarraCuda desktop drive

The Seagate BarraCuda ST1000DM003 is a 3.5 inch internal hard drive with 1 TB capacity, 7200 RPM spindle speed and 64 MB cache. It connects through a SATA 6.0 Gb/s interface and uses 1 TB per disk technology. This drive suits desktop PCs that need bulk storage for documents, media or backups.

Before ordering

Verify that your motherboard or controller provides a free SATA data port and that the power supply has a spare SATA power connector. The 3.5 inch form factor requires a standard drive bay or mounting bracket inside the chassis. Ensure the operating system supports drives of this capacity.

Build and daily use

The bare drive ships without cables, brackets or screws, so installers must supply their own mounting hardware. A SATA data cable and SATA power lead are needed for connection. The 4.16 ms average latency and 7200 RPM speed deliver responsive access for everyday desktop workloads.
