What this drive is and who it fits

The Toshiba MK1633GSG is a 160GB 1.8" laptop hard drive with a 5400 RPM spindle and 16MB cache. It connects through a SATA 3.0Gb/s interface and is packaged as a retail unit. This drive suits owners of older ultraportable notebooks or embedded systems that require the 1.8" form factor and a SATA connection.

What to verify on your system

Confirm that your device accepts a 1.8" SATA hard drive and provides the correct connector for this form factor. Check the physical mounting points and available space inside the chassis, as 1.8" drives differ from standard 2.5" units. Ensure the system BIOS or controller supports a 160GB capacity drive.

Thermals noise and power in daily use

A 5400 RPM spindle generally produces modest heat and low acoustic output suitable for quiet ultraportable environments. Average seek time is 15ms with 5.6ms latency, indicating typical mechanical activity levels for this class. Power draw remains within normal limits for a 1.8" SATA drive during regular read and write operations.
