200 GB 7200 RPM laptop drive

This 2.5 inch hard drive uses a SATA 1.5Gb/s interface and spins at 7200 RPM with 16MB cache. It is built with third-generation PMR technology and rated for 10ms average seek time and 4.2ms average latency. The bare drive is suited to replacing a failed internal drive in an older notebook.

Suits older SATA notebooks only

Buyers needing a 3 Gb/s or 6 Gb/s SATA link should look elsewhere, as this unit is limited to 1.5 Gb/s. Systems requiring more than 200 GB of internal storage cannot use this capacity. The 2.5 inch form factor will not fit 3.5 inch bays or M.2 slots.

SATA 1.5Gb/s interface speed decides fit

The drive connects through a first-generation SATA port running at 1.5 Gb/s, so the host controller must support that exact speed. If the laptop or adapter only offers newer SATA revisions without backward compatibility, the drive will not be recognised.

Questions about this item

Does the 2.5" form factor fit a standard laptop SATA bay?

Yes, the 2.5 inch form factor matches the standard laptop drive bay for a SATA 1.5Gb/s interface.

What is the correct way to connect the SATA 1.5Gb/s interface during installation?

Align the SATA data and power connectors with the motherboard ports and press straight in; forcing the connector at an angle is the step most people get wrong.

When should the 200GB drive be replaced based on its mechanical rating?

The 7200 RPM mechanism with 10ms average seek time and 4.2ms average latency is covered by a three-year limited period; plan replacement around that interval.
