Largely true, but some disk drives (RP06? RP04?) use
3-phase spindle
motors.
The RP06 has 3-phase power input (and output, phase-rotated, for a second
drive), but uses a single phase spindle motor. The US version runs the
spindle between two phases, nominally 208V, but the motor is rated for
operation on a range that spans 208V and 240V.
