What you're looking at here on your left was called Parallel ATA, which, it was parallel 'cause it had a whole bunch of wires in here that all were talking at the same time. Now, over here on the right is a drive known as SCSI, stands for Small Computer Systems Interface. This drive, which is about 25 years old right here by the way, used a parallel interface, you'll notice it's wider, that kind of had its own type of connection.
