3TB Desktop Drive for Everyday Computing

The Seagate BarraCuda ST3000DM008 is a 3.5 inch internal hard drive built for daily desktop workloads. It spins at 7200 RPM with a 64MB cache and connects through a SATA 6.0Gb/s interface. The 3TB capacity suits users who need more room for applications, media libraries and backups in a single bay.

Suits Standard Desktop Builds.

This drive fits typical desktop chassis, all-in-one PCs, home servers and entry-level direct-attached storage devices that accept a 3.5 inch form factor. Buyers upgrading a notebook or any system limited to a 2.5 inch slot cannot use this unit. The bare-drive packaging also means no mounting screws or cables are included.

7200 RPM Spindle Speed Decides Responsiveness

The 7200 RPM rotation rate determines how quickly the platters serve data for boot, launch and large-file streaming tasks. If your workload demands the lower latency of solid-state storage, this mechanical drive will not meet that requirement. For capacity-first desktop storage where mechanical speed is acceptable, the spindle rate is the key figure to evaluate.

Questions about this item

What are the exact dimensions of the 3.5" ST3000DM008 drive?

The drive measures 146.99 mm long, 101.85 mm wide and 26.11 mm high, so it fits any standard 3.5-inch desktop bay.

What is the most common mistake when installing this SATA 6.0Gb/s drive?

People often forget to connect both the SATA data cable and the separate SATA power connector from the PSU; the drive will not spin up without both.

How long can the 7200 RPM mechanism be expected to last before replacement?

The BarraCuda family has over 20 years of field history; under normal desktop workloads the drive typically runs for many years before a replacement is needed.
