Ideal legacy laptop replacement

The Toshiba MK8034GSX is an 80GB 2.5 inch laptop hard drive built for older SATA 1.5Gb/s notebooks. It spins at 5400 RPM with an 8MB cache and a 12ms average seek time. The bare-drive unit fits standard 9.5mm bays and carries a 300,000-hour MTTF rating.

Not for high-capacity or modern-interface needs

This drive suits repair jobs on vintage laptops or low-demand external enclosures where 80GB is sufficient. It is not for users who need more storage, faster spindle speeds, or a newer SATA interface revision. The 1.5Gb/s link limits throughput on current platforms.

SATA 1.5Gb/s interface decides fit

The single specification that determines compatibility is the SATA 1.5Gb/s interface. The host system must support this first-generation SATA link; drives requiring 3Gb/s or 6Gb/s signalling will not operate correctly on this unit.
