Capacity and Interface

The Seagate BarraCuda XT ST32000641AS is a 2TB desktop internal hard drive with a SATA 6.0Gb/s interface. It spins at 7200 RPM and includes a 64MB cache for responsive data access. The 3.5-inch form factor fits standard drive bays in towers and rackmount chassis.

Best-Fit Applications

The drive targets high-performance PC gaming systems, high-definition video editing and production systems, home servers and workstations, desktop RAID arrays, and FireWire 800- or eSATA-enabled external storage devices. These uses benefit from the sustained throughput of the 7200 RPM spindle and large cache.

Average Latency

The published average latency is 4.16ms, reflecting the rotational speed and cache architecture. This figure helps determine whether the drive meets the response-time requirements of a given server or workstation workload. Buyers who need lower latency for transaction-heavy databases should consider solid-state alternatives.

Questions about this item

What is the 3-year limited period that comes with this ST32000641AS?

The manufacturer provides a 3-year limited warranty on the drive.

Does the 7200 RPM speed or the SATA 6.0Gb/s link become the bottleneck first during long writes?

The 7200 RPM spindle sets the sustained throughput ceiling; the SATA 6.0Gb/s link has higher headroom.

How much noise and heat should I expect from the 3.5" 7200 RPM mechanism running all day?

A 7200 RPM 3.5" drive produces audible seek noise and measurable warmth; ensure case airflow.
