Purpose and capacity

This Seagate Desktop HDD provides 3TB of storage on a 3.5 inch form factor for daily computing workloads. It operates at 7200 RPM with a 64MB cache and connects through a SATA 3.0Gb/s interface. The bare drive measures up to 26.11mm high, 101.60mm wide and 146.99mm long.

Who it suits and who it does not

Builders needing a high-capacity mechanical drive for bulk files, backups or secondary storage will find it appropriate. Buyers who want faster random access, silent operation or a smaller 2.5 inch footprint should look at solid-state alternatives. Systems limited to SATA 1.5Gb/s ports will still work but at reduced throughput.

Installation checks

Verify that the chassis has a free 3.5 inch bay and that the power supply includes a spare SATA power connector. Confirm the motherboard or controller offers an available SATA data port running at 3.0Gb/s or backwards-compatible speeds. Ensure the operating system supports drives larger than 2TB or plan to use the supplied DiscWizard software for legacy BIOS environments.

Questions about this item

Does my motherboard need a SATA 3.0Gb/s port to use this 3.5" 3TB drive?

Yes, the ST3000DM001 connects through a standard SATA 3.0Gb/s interface, so the board must provide a matching SATA data connector and a SATA power lead from the PSU.

Can I run this 7200 RPM drive on the same SATA controller as an older 3.0Gb/s mechanical disk?

Both drives will operate at the SATA 3.0Gb/s link speed; the controller will negotiate the lowest common rate, so the older disk will not slow the new drive beyond that limit.

How can I verify the 64MB cache and 7200 RPM are active after installation?

Check the drive properties in Device Manager or run a SMART utility such as CrystalDiskInfo; it will report 7200 RPM rotational speed and 64MB buffer size for the ST3000DM001.
