Capacity and interface

The Seagate BarraCuda ST3000DM007 is a 3TB 3.5-inch desktop internal hard drive with a SATA 6.0Gb/s interface. It spins at 5400 RPM and includes a 256MB cache for everyday storage tasks. The drive measures 20.20mm in height, 101.85mm in width and 146.99mm in length. It is supplied new and suited for daily computing workloads.

Who this suits and who should look elsewhere

This drive fits builders adding bulk storage for documents, media libraries or backups in a standard desktop chassis. Buyers needing higher spindle speeds for intensive random access or lower latency for primary operating system boot should consider a different class of storage. The 3.5-inch form factor requires a compatible drive bay and SATA power and data connections.

Deciding specification

The 5400 RPM spindle speed is the single figure that determines whether this drive matches the workload. It delivers the throughput expected for sequential file storage and archival use at this capacity. Systems requiring faster random access performance will not achieve that target with this rotational speed.

Klausimai apie šią prekę

How often should I plan to replace the mechanical platters or motor in the ST3000DM007 after continuous daily use?

The drive has no user-serviceable platters or motor; Seagate rates the BarraCuda family for typical desktop workloads and the unit is covered by the manufacturer's standard limited warranty period.

What is the first performance limit I will hit when writing large files continuously to the 3TB SATA 6.0Gb/s drive?

Sustained throughput is capped by the 5400 RPM spindle speed and the 256MB cache, so the mechanical media transfer rate becomes the bottleneck before the SATA 6.0Gb/s interface saturates.

How much heat and noise does the 3.5-inch 5400 RPM drive produce when it runs all day in a desktop case?

At 5400 RPM the drive operates at typical desktop acoustics and thermal output; advanced power modes reduce energy use during idle periods, keeping case temperatures and noise at normal levels for a 3.5-inch hard drive.
