Desktop hard drive for basic storage

This Seagate BarraCuda 7200.12 drive provides 250GB of internal storage in a 3.5 inch form factor. It operates at 7200 RPM with an 8MB cache and uses perpendicular magnetic recording technology. The unit is supplied as a bare drive and is new condition.

SATA 3.0Gb/s interface throughput limit

The drive connects via a SATA 3.0Gb/s interface which caps the maximum theoretical transfer rate at 3.0 gigabits per second. Real world sustained speeds will be lower due to mechanical latency and command overhead. Average latency is specified at 4.16ms for random access operations.

250GB capacity decides suitability

This capacity determines whether the drive meets your storage requirement for an operating system, applications or data archive. At 250GB it suits lighter workloads or secondary roles rather than large media libraries. Buyers who need more storage should consider higher capacity models.

Questions about this item

Is the 250 GB capacity enough for a basic desktop build?

The 250 GB capacity suits a basic desktop build with an operating system, essential programs and light personal files.

What does the 7200 RPM speed mean for everyday use?

The 7200 RPM spindle speed and 4.16 ms average latency give quicker file access than slower drives, improving boot times and application loading.

Will the SATA 3.0 Gb/s interface limit performance on a modern motherboard?

The SATA 3.0 Gb/s interface caps the maximum transfer rate at 3.0 Gb/s, so a faster motherboard port will not increase the drive’s own throughput.
