Of course if you use anything like Oracle7 Release 7.1 Parallel Query, and you have only one disk containing all data, disk I/O will be a bottleneck. Features like Parallel Operations are only useful if you have enough disk bandwidth, so have multiple (fast) disks and controllers and spread the data over your disks.
