It's a myth. Amstrad computers were already using 3 inch drives in 1984, way before 3.5 inch ones became popular. The drives were chosen due to their similarity to 5.25 drives, so that existing controller chips could be reused. Due to the huge volume of ordered drives, Amstrad did get huge discounts on them, but that had nothing to with the drives becoming obsolete.
