What this drive is and who needs it

The Seagate Barracuda ST2000DM001 is a 2 TB 3.5 inch desktop internal hard drive spinning at 7200 rpm with a 64 MB buffer. It connects through a SATA 600 interface and uses 1 TB per disk technology to deliver high capacity in a standard form factor. The drive is sold new and suits desktop PCs that need large, affordable bulk storage.

Who should buy it and who should not

This drive suits users who want a mechanical drive for mass data such as media libraries, backups or archival files in a desktop chassis. It is not for builders who need solid-state speed for an operating system or applications, nor for systems that lack a 3.5 inch bay or a SATA power and data connection. Buyers wanting silent operation or shock resistance should look at solid-state alternatives.

The specification that decides fit

The SATA 600 interface is the single specification that decides whether this drive fits the build. The motherboard or controller must provide a standard SATA 7 pin data port and matching power connector. If the platform only offers M.2 slots or another interface, this drive cannot be installed without an adapter.

Questions about this item

Does my desktop case have a free 3.5 inch bay and a SATA power cable for this drive?

Yes, the drive uses a standard 3.5 inch form factor and connects via a SATA/600 interface, so it needs an open 3.5 inch bay, a SATA data cable and a SATA power connector from your power supply.

Will this 7200 rpm SATA drive work on a motherboard that only supports SATA 3 Gbit/s?

The SATA/600 interface is backward compatible with older SATA revisions, so the drive will function on a 3 Gbit/s port at the slower link speed.

How can I confirm the 64 MB buffer is active after installation?

Check the drive details in your operating system or BIOS; the reported cache size should show 64 MB, and SMART data will confirm the drive is communicating over SATA/600.
