Suits older laptops and server roles

The 7200 RPM speed and 250GB capacity suit users upgrading an older SATA laptop or adding storage to a compatible server bay. Buyers needing larger capacities or a faster interface for a modern system should look at something else. The 9.5mm height fits standard drive bays.

SATA 3.0Gb/s interface decides fit

Questions about this item

Should I choose the 250GB 7200 RPM model or a 5400 RPM alternative?

The 250GB capacity with 7200 RPM and 16MB cache delivers higher performance than 5400 RPM drives while drawing only 0.05 percent more power.

What does the 7200 RPM speed mean for actual laptop use?

7200 RPM reduces average latency to 4.17ms, giving faster boot times and application loading compared to slower laptop drives.

Will the SATA 3.0Gb/s interface limit transfer rates in my system?

The SATA 3.0Gb/s interface caps the maximum burst transfer rate at 3.0 Gb/s; sustained speeds depend on the 7200 RPM platters and 16MB cache.
