Desktop storage with 500GB capacity

The Seagate BarraCuda 7200.9 ST3500641AS-RK is a 3.5 inch internal hard drive built for desktop computers. It provides 500GB of storage on a SATA 6.0Gb/s interface with a 7200 RPM spindle speed and 16MB cache. The drive measures 146.05mm long, 101.60mm wide and 22.23mm high. It is supplied in a retail kit and is new condition.

Suits desktop towers and basic NAS builds

This drive fits standard desktop performance towers, all-in-one PCs and consumer-grade NAS devices or desktop RAID arrays. Buyers needing higher capacities or faster solid-state speeds should consider other options. The 16MB cache and 7200 RPM rotation serve general desktop workloads and bulk storage requirements.

Sustained throughput on mechanical media

Under continuous load the 7200 RPM platters and 16MB cache deliver steady data rates across the SATA link. The fluid dynamic bearing motor keeps acoustic output low during extended read or write sessions. Mechanical latency and rotational speed define the sustained performance envelope rather than burst transfer figures.

Questions about this item

What SATA port speed does my motherboard need to support the ST3500641AS-RK at full 6.0Gb/s?

The drive uses a SATA 6.0Gb/s interface; it will operate at the port's maximum negotiated speed.

Will the BarraCuda 7200.9 run reliably with an older SATA 3Gb/s drive in the same system?

Yes, each device negotiates its own link speed independently on the SATA bus.

How can I verify the 7200 RPM motor and 16MB cache are active after installation?

Check the drive's reported RPM and cache size in BIOS or a tool such as CrystalDiskInfo.
