Regular ATA ran at 33 and 66 Mhz transfer rates. When that changed to 100 and 133 Mhz rates they changed cables and name

Interface Speed: Both IDE/ATA and SCSI operate at several standard speeds. For IDE/ATA drives the current standard is Ultra ATA/100, with the "100" standing for the interface's maximum potential throughput, 100 MB/s. In theory, faster interface drives are better, but for most PCs the speed of the interface has little impact on overall hard disk performance, as long as the number is above the maximum sustained transfer rate of the drive (see under "magic numbers" below for more). If you want to run an Ultra ATA/100 drive you need a controller that supports Ultra ATA/100, but even a controller that runs at 66 or 33 MB/s theoretical bandwidth will work OK; the drives are backward compatible.
