BarraCuda 2 TB 7200 RPM SATA Drive

The Seagate BarraCuda ST2000DM008 is a 2 TB 3.5 inch desktop hard drive that spins at 7200 RPM and connects through a SATA 6.0 Gb/s interface. It carries a 256 MB cache and measures 146.99 mm long, 101.85 mm wide and 20.20 mm high. The drive is supplied new and is built for everyday computing tasks.

Suits general desktop storage and bulk data

This drive fits users who need affordable high-capacity storage for documents, media libraries or backup on a standard desktop PC. Buyers who require the low latency or high sustained throughput of solid-state storage should consider a different technology. Systems limited to the older SATA 3.0 Gb/s standard will not reach the interface burst speed this model offers.

SATA 6.0 Gb/s interface decides compatibility

The single specification that determines whether this is the correct part is the SATA 6.0 Gb/s interface. Your motherboard or controller must provide a matching SATA port to install the drive and achieve its rated burst performance. Without that port the drive will not function as intended.

Questions about this item

What practical throughput does the SATA 6.0Gb/s interface cap at on this drive?

The SATA 6.0Gb/s interface supports up to 6.0Gb/s burst speeds, while sustained transfer rates are limited by the 7200 RPM platters and 256MB cache.

Will the 146.99mm length and 20.20mm height fit a standard 3.5" desktop bay?

Yes, the drive measures 146.99mm long, 101.85mm wide and 20.20mm high, matching the standard 3.5" form factor used in desktop cases and drive cages.

How do I install this bare drive, and which step is often missed?

Mount the drive using four 3.5" screws, connect a SATA data cable to the motherboard and a SATA power cable from the PSU, then initialise and format the 2TB volume in the OS — the formatting step is frequently overlooked.
