Our take on the Seagate ST2000DM008 Barracuda 2TB 3.5-inch Internal Hard Drive

The Seagate Barracuda ST2000DM008 is a 2TB 3.5-inch desktop hard drive spinning at 7200 RPM with a 256MB cache on a SATA 6Gb/s interface. Its large cache and 7200 RPM spindle make it a solid bulk-storage and backup drive for a desktop PC, and it is one of the better-specced 2TB mechanical drives at its tier. It is not an SSD: expect hard-drive speed, not instant load times. Buyers rate it highly for capacity and reliability, though some report noise and occasional early failures typical of mechanical drives.

Questions and answers

Is this drive fast enough for a Windows install?
It works, but an SSD is much faster for the operating system. Use the Barracuda for storage and backups instead.
Will it fit my desktop?
It is a standard 3.5-inch drive with a SATA interface, so it fits most desktop cases and drive bays.
Is it good for a NAS?
Seagate positions the Barracuda for desktop PCs, not always-on NAS use. For a NAS, look at drives rated for continuous operation.
What is the cache size?
It has a 256MB cache, which is large for a 2TB mechanical drive and helps with burst transfers.

Internal drives typically ship as the bare drive. You will usually need a SATA data cable and a power connector from your PC.
