Which hard-drive spindle speed would typically deliver the fastest sequential read/write performance in a conventional magnetic (HDD) drive, assuming all other factors are equal?
4,500 RPM
5,400 RPM
7,200 RPM
10,000 RPM
In magnetic hard drives, faster rotational speed moves more surface area under the read/write heads each second, reducing rotational latency and increasing the linear data rate. Among the listed options, a 10 000 RPM drive spins the platters much faster than 5400, 7200, or 4500 RPM models, so it usually provides the highest sustained transfer rates and quickest access times.
