320 GB SATA laptop drive

The Toshiba MK3265GSX is a 2.5 inch internal hard drive with 320 GB capacity and a 5400 RPM spindle speed. It connects through a SATA 3.0Gb/s interface and includes an 8 MB cache. The drive is suited for replacing storage in laptops or mini notebooks where a 2.5 inch SATA bay is available.

Compatibility checklist

Verify that the system uses a 2.5 inch SATA drive bay with a 3.0 Gbit/s interface. The physical dimensions are 2.8 inch width, 3.9 inch depth and .4 inch height. The drive is hot swappable and meets RoHS environmental certification. No additional cables or adapters are included with the bare drive package.

Build integration

The SATA interface fits directly into standard laptop drive bays and compatible enclosures. Power consumption and heat dissipation are reduced by over 80 percent compared to similar 3.5 inch drives. An MTTF rating of 600000 hours and an average seek time of 12ms support reliable operation. Buyers needing higher capacities or faster spindle speeds should consider other models.

Questions about this item

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

The drive is supplied as a bare unit only; mounting screws and any SATA data or power cables must be obtained from the laptop chassis or a separate kit.

Is the 320 GB / 5400 RPM / 8 MB cache version the only configuration offered for the MK3265GSX?

The MK3265GSX is sold in this single 320 GB capacity with 5400 RPM spindle speed and 8 MB buffer; no other capacity or speed variants exist for this model number.

What does the 3.0 Gbit/s SATA interface actually deliver inside a laptop?

The SATA 3.0 Gbit/s link supports up to 300 MB/s interface bandwidth; real-world throughput is limited by the 5400 RPM mechanics and 12 ms average seek time.
