To very broadly generalize 33MB/s sustainable is a limitation of
physically reading the disk, not the interface from the motherboard to the
disk.  All the ATA66, ATA100, and ATA133 specs are about burst speed
(basically reading from the disk's on board cache).  Alternatives for
faster sustainable speeds would include: faster spinning SCSI disks, RAID,
non-mechanical hard drives.
