Capacity and interface

The Seagate BarraCuda 7200.10 ST3200820AS is a 200GB 3.5-inch internal hard drive with a SATA 3.0Gb/s interface spinning at 7200 RPM and an 8MB cache. It is suited for desktop systems and server builds that require a traditional mechanical drive for bulk storage.

Bare drive packaging

The drive ships as a bare unit without cables, mounting brackets or installation software. Perpendicular recording technology is used to achieve the stated capacity and reliability, while Enhanced G-Force Protection and Clean Sweep calibration help guard against handling damage and maintain data integrity.

Build and connectors

The 3.5-inch form factor fits standard drive bays and uses the SATA data and power connectors common to desktop chassis and server backplanes. Whisper-quiet operation and an average seek time of 8.5ms with 4.16ms latency make it appropriate for environments where low noise and consistent mechanical performance are valued.

Questions about this item

Will the 8 MB cache or SATA 3.0 Gb/s interface need an upgrade later?

The 8 MB cache and SATA 3.0 Gb/s interface are fixed hardware on this drive; they cannot be upgraded, but the drive will continue to operate with any system that supports SATA.

What limits sustained throughput on the ST3200820AS during long write sessions?

The 7200 RPM spindle speed and 8 MB cache set the sustained transfer ceiling, while the SATA 3.0 Gb/s link caps the interface rate at 3.0 Gb/s.

How much heat and noise does this 7200 RPM drive produce when running all day in a server?

Seagate rates the BarraCuda 7200.10 for whisper-quiet operation; typical 7200 RPM 3.5" drives draw under 10 W idle and stay within normal desktop thermal limits.
