Only a few years ago, SCSI drives used to be far superior to IDE models. Today the picture has changed. It comes to no surprise that SCSI has finally disappeared from the home and office segment. IDE hard drives are offering excellent performance, large capacities at a very reasonalbe price. SCSI is a lot more expensive and complicated to set up, while hardly offering any benefit to the home or office user.
Large RAIDs are one example.
Then you can connect 7 or 14 devices to the SCSI-adapter, like CDRWs, Scanners, of course hard drives and more. Times for SCSI are hard. Most hard drive manufacturers are focussing more and more on IDE drive development. It has become difficult to develop SCSI components that are significanty better than IDE products, especially if the developer wants to meet reasonable price points. At this point we are seeing a clear split.
