No, the difference is in the channel technology.
  • A SCSI bus allows simultaneous transfers between the host and multiple targets. So your OS can read from one disk while writing to another, which is the biggest advantage. In addition, one can string many devices onto a single SCSI bus, if necessary. In addition, the SCSI bus can be shared by multiple computing systems -- allowing for shared storage systems, but not shared devices.
  • IDE is limited to a communicating with a single device at a time, and has a maximum of two peripheral devices per bus, with a single host.
