difference between the UDMA 66 drives vs ATA 66? I
Not really. In essence those are two names for the same thing.
This 66 MB/sec transfer rate is similar with scsi.
Well, only if your mobos chipset does support UDMA66 *and* you use the special ATA66 cable. And even then not quite :) There's currently *no* ATA drive on this planet that even gets near that transfer rate (only between the drive controllers cache and the mobo). The best of the current drives get nearly 30 MB, but that's the most. And as ATA drives can't disconnect from the bus in order to to let other drives receive their commands, the theoretical maximum of 66 MB/sec will not be utilized for quite some time to come. So you could have saved even further if there had been an UDMA33 drive with the same capacity available. ATA66 is mainly a marketing vehicle, invented to let ATA speeds approx. match SCSI rates on paper and to get users to upgrade their hardware.
