Enterprise-class capacity

The Seagate BarraCuda ES.2 ST3500320NS is a 500GB 3.5-inch internal hard drive built for 24x7 operation in enterprise storage environments. It spins at 7200 RPM with a 32MB cache and connects through a SATA 3.0Gb/s interface. The bare-drive packaging suits system integrators and IT departments deploying arrays or replacing failed units in existing servers.

Sustained-load behaviour

Designed for continuous duty, the drive offers best-in-class rotational vibration tolerance to maintain performance in multi-drive chassis. Average latency sits at 4.16ms, and the 7200 RPM spindle speed supports steady throughput during long write sequences. The 32MB buffer helps smooth burst traffic without throttling under prolonged workloads.

Upgrade context

This model delivers 33 percent more capacity than the earlier Barracuda ES drive while keeping the same 1.0-inch low-profile height. It fits legacy 3.5-inch bays using SATA 3.0Gb/s controllers, making it a direct replacement for older enterprise SATA drives. Buyers needing higher areal density or newer interfaces will not be served by this generation.

Soalan tentang produk ini

How much power does the 7200 RPM ST3500320NS draw during continuous 24x7 operation?

The drive is designed for 24x7 enterprise use with rotational vibration tolerance, though the exact wattage figure is not supplied.

Does the bare drive ST3500320NS include the SATA data and power cables I need to install it?

No, the bare drive packaging means you must supply your own SATA data cable and a SATA power connector from the power supply.

Will the SATA 3.0Gb/s interface on this 3.5" drive work with my older SATA 1.5Gb/s motherboard port?

Yes, the SATA 3.0Gb/s interface is backward compatible with SATA 1.5Gb/s ports, operating at the lower speed.
