Product Identity

Suitability

This drive suits upgrades for compatible notebooks or small-form-factor desktops that accept a 2.5-inch SATA drive. Builders who need a 3.5-inch form factor, a different interface, or higher rotational speed should consider other options.

Deciding Specification

Questions about this item

Will this 2.5" SATA 3.0Gb/s drive work in an older laptop that only supports SATA 1.5Gb/s?

Yes, the SATA 3.0Gb/s interface is backwards compatible with SATA 1.5Gb/s controllers, so the drive will function at the slower speed.

How can I verify the drive is running at its rated 7200 RPM after installation?

Use a tool like CrystalDiskInfo or the SMART data in your BIOS to confirm the rotational speed shows 7200 RPM and the SATA link is negotiated at 3.0Gb/s.

Does the MK1661GSYB include a mounting bracket or SATA cable for a desktop PC?

The drive is supplied as a bare 2.5" unit; a 2.5-to-3.5" adapter bracket and a standard SATA data cable must be purchased separately for desktop use.
