Capacity and intended use

The Seagate ST3500414CS is a 500 GB 3.5 inch internal hard drive spinning at 5900 RPM with a 16 MB cache. It connects via a SATA 3.0Gb/s interface and is designed for daily computing workloads in desktop systems.

Before ordering

Verify that your motherboard provides a free SATA 3.0Gb/s port and that the power supply includes a spare SATA power connector. The drive ships as a bare unit without cables, brackets or mounting screws, so ensure you have those parts available. Note that the media may contain up to 25 bad sectors and has been erased to DoD 5220.22 M compliance.

Build integration

The 3.5 inch form factor fits standard desktop drive bays and requires mechanical mounting plus both data and power cables. Its 5900 RPM speed and 16 MB buffer deliver steady throughput for everyday tasks while leaving higher performance tiers free for operating system or application drives. Average seek times are below 14.0 ms for reads and 15.0 ms for writes with 5.1 ms average latency.

Questions about this item

Does the bare drive include mounting screws or a SATA cable, or do I need to buy them separately?

The ST3500414CS is supplied as a bare 3.5-inch drive only; mounting screws and SATA data or power cables are not included and must be sourced separately.

The listing mentions 5900 RPM and 16 MB cache — how do those figures affect everyday desktop use?

The 5900 RPM spindle speed and 16 MB cache are tuned for typical daily computing workloads such as OS boot, application launch and file storage on a SATA 3.0Gb/s link.

What does the <14.0 ms read seek time mean once the drive is installed in a real system?

An average read seek below 14.0 ms combined with 5.1 ms latency means the head positions quickly enough for ordinary desktop tasks, though random I/O will be slower than on higher-RPM drives.
