Enterprise-class 500 GB SATA drive

The Seagate Barracuda ES ST3500630NS is a 3.5-inch internal hard drive built for desktop and entry-level server workloads. It spins at 7200 RPM and connects via a SATA 3 Gb/s interface with a 16 MB cache buffer. The drive is supplied new and carries a 90-day warranty period.

Suited for bulk storage and legacy arrays

This drive fits systems that need affordable high-capacity storage on a 3 Gb/s SATA link, such as RAID rebuilds, archival servers or older workstations. Builders who require faster 6 Gb/s throughput, larger caches or solid-state latency should look at alternative technologies.

Fits standard 3.5-inch bays with SATA power and data

The unit mounts in any 3.5-inch drive bay and uses standard SATA power and data cables. Its 500 GB capacity adds substantial space without needing a modern controller, freeing faster ports for boot drives or caching devices.

Questions about this item

What SATA port speed does my motherboard need to run this ST3500630NS at its native 3Gbps interface?

The drive connects via a standard SATA 3Gb/s port; any motherboard with a SATA revision 2.x or 3.x connector will run it at its rated 3Gbps link speed.

Will this 500GB 7200RPM Barracuda ES work reliably alongside an older IDE drive on the same system?

Yes, the SATA interface is electrically independent from legacy IDE channels, so the 500GB 7200RPM drive can share a system with an older IDE drive without conflicts.

After installing the ST3500630NS, how can I verify the 16MB cache is active and the drive spins at 7200RPM?

Check the drive's reported cache size and rotational speed in the BIOS hardware monitor or with a tool such as CrystalDiskInfo; both should show 16MB buffer and 7200RPM.
