1 TB desktop hard drive

The Seagate ST1000DM003 provides 1 TB of storage on a 3.5 inch form factor designed for desktop computers. It spins at 7200 RPM with a 64 MB cache and connects through a SATA interface. The drive uses Advanced Format technology for efficient data organisation.

SATA interface and 3.5 inch mounting

A standard SATA data and power connector allows direct installation in any desktop drive bay or caddy that accepts 3.5 inch drives. The 7.2K RPM spindle speed delivers consistent throughput for everyday workloads such as operating system drives, bulk storage or surveillance recording. OEM packaging means no retail accessories are included.

Check bay space and SATA ports

Verify that your chassis has a free 3.5 inch bay and that the motherboard or controller offers an available SATA port before ordering. Ensure the power supply includes a spare SATA power connector for the drive. This unit is not suited for laptop bays or systems that only support 2.5 inch drives.
