Desktop 250GB SATA drive

This 3.5-inch internal hard drive delivers 250GB of storage for desktop computers. The 7200RPM spindle speed and 16MB cache support everyday computing tasks and general file storage. It connects via a SATA 3Gb/s interface and is sold new. The unit weighs 2.0 pound.

Sustained 7200RPM operation

Under continuous workloads the 7200RPM motor maintains consistent rotational speed for steady data throughput. The 16MB buffer helps smooth burst transfers during prolonged read or write sessions. Mechanical latency remains constant because the spindle does not throttle down. Performance scales with the SATA 3Gb/s link ceiling.

Verify 3.5-inch bay and SATA port

Confirm your chassis has a free 3.5-inch drive bay and a spare SATA data connector on the motherboard or controller. Ensure the power supply provides a SATA power lead for the drive. The 90-day warranty period applies from the date of purchase. This drive is intended for desktop systems only.
