Seagate Decathlon 850 (1995)

revolutions: 3600 > 4500 > 7200 rpm

At about the same time that the 528MB limit was finally overcome, drive manufacturers turned their attention to performance, in particular by lifting spin rates from the traditional 3600 RPM to 4500, and in some cases to 5400.

This made a huge difference, and some of the true classics of hard drive history were produced during this era, including the orginal Quantum Fireballs and the Seagate Decathlons.
