Drive Identity

Fit and Limits

It suits owners replacing a failed 2.5-inch SATA drive in an older notebook or using the drive in a compatible external enclosure. Builders who need a larger capacity, a faster solid-state drive, or a different physical form factor should look elsewhere.

Questions about this item

Should I choose the 250 GB version or a larger capacity for my laptop?

The 250 GB MK2561GSYB is the only capacity offered for this model; if you need more space you must select a different drive.

What does the 7200 RPM spindle speed deliver in daily use?

The 7200 RPM rotation provides quicker data access and shorter load times than slower-spinning laptop drives.

Will the SATA 3.0 Gb/s interface limit performance on a modern motherboard?

The drive runs at SATA 3.0 Gb/s, so sustained throughput will not exceed that link speed even on a faster SATA controller.
