Enterprise Storage Drive

The Seagate BarraCuda ES.2 ST31000340NS is a 1TB 3.5-inch internal hard drive built for 24x7 operation in business-critical environments. It spins at 7200 RPM with a 32MB cache and connects via a SATA 3.0Gb/s interface. Perpendicular recording technology increases data density while reducing moving parts for enhanced reliability.

Compatibility Checklist

Verify that your system has a free 3.5-inch drive bay and a SATA data port running at 3.0Gb/s. The bare-drive package includes no cables, brackets or mounting screws, so confirm you have spares or can source them separately. Ensure your BIOS or operating system supports drives of this capacity without additional software.

Upgrade Path

This model delivers 33 percent more capacity than the earlier Barracuda ES drive while maintaining the same enterprise-grade reliability. OptiCache technology improves performance by up to 45 percent, and SmartAlign eases the transition to Advanced Format 4K sectors. The jump is worth it for arrays needing higher density and sustained throughput in multi-drive deployments.

商品問答

What comes with the bare drive ST31000340NS and what must I buy separately?

The drive ships as a bare unit only; you will need to supply your own SATA data cable, SATA power cable and 3.5" mounting screws or tray.

Which capacity version of the BarraCuda ES.2 should I choose for enterprise storage?

This model provides 1TB on a 7200 RPM platform with 32MB cache and SATA 3.0Gb/s interface, the only capacity listed for this part number.

What does the 7200 RPM rating mean once the drive is installed in a server?

It delivers 4.16ms average latency and sustained throughput suitable for 24x7 multi-drive arrays, with rotational-vibration tolerance built for enterprise workloads.
