Seagate 250GB 2.5" SATA Laptop Drive

This new Seagate ST9250421AS is a 250GB 2.5-inch internal hard drive built for laptop storage upgrades or replacements. It connects via a SATA 3.0Gb/s interface and spins at 7200 RPM. The bare-drive packaging suits installers who do not need retail accessories.

Ideal for Older SATA Notebooks

The drive fits 2.5-inch SATA bays in compatible notebooks and can serve as a primary boot drive or secondary data store. Buyers whose systems require a faster solid-state interface or a larger capacity should consider other options. Laptops limited to lower spindle speeds may not benefit fully.

7200 RPM Spindle Speed

The 7200 RPM rotation rate is the key performance figure for this model. It determines the drive's sustained throughput and access latency within the SATA 3.0Gb/s link. Verify that the target notebook supports this speed and the 2.5-inch form factor before purchase.

Questions about this item

Should I choose the 250GB 7200 RPM model or a lower-capacity version?

This drive provides 250GB of storage at 7200 RPM. Select it when you need that capacity and speed combination; smaller capacities are separate part numbers.

What does the 7200 RPM rating mean for everyday laptop use?

The spindle spins at 7200 RPM, so data reaches the read-write heads more quickly than on slower-spinning drives, reducing wait times when opening files or launching programs.

Will the SATA 3.0Gb/s interface limit performance in my notebook?

The SATA 3.0Gb/s link caps the theoretical transfer rate at 3.0 Gb/s, so sustained throughput cannot exceed that ceiling even if the drive mechanics are faster.
