"Is ATA/66 really necessary. We've seen all of the synthetic benchmarks saying that ATA/66 is twice as fast as ATA/33, which it should be, being it transfers data at twice the speed. In the real world, it doesn't transfer twice as fast. That is mainly because the interface isn't the bottleneck in today's drives. It's actually the rotational speed of the disks inside the hard drive. The majority of the drives on the market today, be them ATA/33 or ATA/66, are spinning at 5400RPM. Some of the newer and faster drives are spinning at 7200RPM. Even with the 7200RPM drives, as we are about to prove, the real world difference between the two interfaces isn't noticeable, because the rotational speed is still a bottle neck."
