500 GB SATA desktop drive

The Seagate Barracuda ES.2 ST3500320NS is a 3.5-inch internal hard drive with a 500 GB capacity and a 7200 RPM spindle speed. It connects via a SATA 3 Gb/s interface and includes a 32 MB cache buffer. The drive is designed for desktop systems that need reliable bulk storage.

SATA 3 Gb/s interface limit

The SATA 3 Gb/s interface caps the maximum theoretical transfer rate at 3 Gb/s, so sustained throughput will not exceed this bandwidth. Mechanical latency and rotational speed determine real-world read and write performance within that ceiling. The 32 MB cache helps smooth burst transfers but cannot overcome the interface bottleneck.

Check SATA port and bay space

Verify that your motherboard or controller provides a free SATA 3 Gb/s port and that your case has an available 3.5-inch drive bay. Ensure the power supply includes a compatible SATA power connector for the drive. Confirm the operating system supports the drive capacity without additional drivers.
