Desktop storage for daily computing

The Seagate BarraCuda ES ST3500630NS is a 3.5-inch internal hard drive built for desktop PCs. It delivers 500GB of capacity over a SATA 3.0Gb/s interface and spins at 7200 RPM with 16MB cache. The drive uses perpendicular recording technology and native command queuing for reliable everyday operation.

Suited for legacy upgrades and secondary storage

This drive fits older desktops, backup arrays or any 3.5-inch bay that still relies on a 3.0Gb/s SATA connection. Its 24 x 7 reliability rating and rotational vibration tolerance support continuous operation. Buyers needing faster sequential throughput, larger capacities or a modern 6Gb/s interface should look elsewhere.

SATA 3.0Gb/s interface defines compatibility

The 3.0Gb/s link is the single specification that determines whether this drive matches your motherboard or controller. Average seek time is 8.5ms, average write time is 10ms and average latency is 4.16ms. Confirm your system supports this interface before purchase.

Questions about this item

Should I pick the 500GB version or a larger capacity for daily computing?

The ST3500630NS is offered in a single 500GB capacity; there is no larger version of this specific model to choose from.

What does the 7200 RPM rating mean for real-world file transfers?

At 7200 RPM with 16MB cache the drive delivers an average seek time of 8.5ms and average latency of 4.16ms, giving responsive performance for everyday desktop workloads.

How does the SATA 3.0Gb/s interface limit actual throughput?

The SATA 3.0Gb/s link caps the theoretical maximum at 3.0Gb/s, so sustained read or write speeds will not exceed that ceiling in practice.
