So, sticking with IDE is a good solution for those of you who are more budget-conscious, or do not have the need for more devices besides your CD-ROM and hard drive. SCSI setups are for power users, or people with some money to burn. SCSI is the solution for people who need device flexibility and different device support, and people in multitasking environments will see the true benefits of SCSI. Of course, don't forget that SCSI and IDE can be mixed together very easily! So if you aren't sure, you can always go SCSI later.
