4 TB Desktop Hard Drive

The Seagate BarraCuda ST4000DM005 is a 3.5 inch internal hard drive with a 4 TB capacity. It spins at 7200 RPM and includes a 64 MB cache. The drive uses a SATA 6.0Gb/s interface and measures 146.99 mm long, 101.60 mm wide and 26.11 mm high. It is sold new as a bare drive.

SATA 6.0Gb/s Interface Limits

The SATA 6.0Gb/s interface sets a maximum theoretical burst rate of 600 MB/s. Sustained transfer speeds depend on the drive’s mechanical performance and system workload. The interface is backward compatible with older SATA revisions. Cable length and host controller quality can affect real-world throughput.

4 TB Capacity Decides Fit

The 4 TB capacity determines how much data the drive can hold. Buyers who need more storage must choose a higher-capacity model. The 7200 RPM spindle speed and 64 MB cache influence responsiveness for daily computing tasks. Verify that the system has a free 3.5 inch bay and a SATA power and data connection.

Questions about this item

Is the 4TB capacity the right choice for my desktop?

The 4TB capacity stores large game libraries, media collections and backups in a single 3.5 inch drive, avoiding the need for multiple smaller units.

What does the 7200 RPM speed deliver in daily use?

The 7200 RPM spindle provides responsive sequential throughput for loading games, applications and large media files on a desktop system.

How does the SATA 6.0Gb/s interface limit real-world transfer rates?

The SATA 6.0Gb/s link caps burst transfers at the interface maximum, while sustained rates follow the 7200 RPM mechanical performance.
