Small Computer System Interface (SCSI)

- The beautiful thing about today's mass storage is the overwhelming popularity of the ATA interface. SATA controls all kinds of hard disk drives and SSDs. It is the thing that we use. Well, not exactly. We need to go back in time a little bit and take a look at some old mass storage devices that I've got right here in front of me. So, take a look at these two guys.

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. The whole idea behind SCSI is that SCSI was developed about the same time as ATA. So they were…
