Capacity and interface
The Seagate BarraCuda 7200.10 ST3400620AS is a 400GB 3.5" internal hard drive with a SATA 3.0Gb/s interface. It suits desktop builders who need a new drive for an older SATA system or a secondary storage volume.
Sustained workload behaviour
The drive spins at 7200 RPM with a 16MB cache, yielding an 8.5ms average seek time and a 10ms average write time. Perpendicular recording technology supports consistent throughput during extended file transfers rather than only in short bursts.
Build quality and daily implications
Enhanced G-Force Protection guards against handling damage while Clean Sweep calibration and Directed Offline scan diagnostics maintain data integrity. The bare-drive packaging means mounting screws and cables must be supplied separately.

商品問答
How much noise and heat does the 7200 RPM mechanism produce during continuous operation?
The drive is described as whisper-quiet and uses perpendicular recording technology, which reduces mechanical chatter while the 7200 RPM spindle runs at a steady speed.
What cables and host interface are required to connect the SATA 3.0Gb/s interface?
You need a standard SATA data cable and a SATA power connector from the power supply; the drive plugs directly into any motherboard or controller with a SATA 3.0Gb/s port.
Will the 3.5 inch form factor and SATA interface work alongside an older IDE drive on the same system?
Yes, the 3.5 inch drive uses a native SATA 3.0Gb/s interface, so it can coexist with legacy IDE devices on a motherboard that provides both SATA and IDE connectors.
