I understand IDE has some issues that make > RAID type devices nonexistant, but what are the reasons? They don't exist, really. You can buy RAID-controllers for IDE. The only issues are that it is slightly more work to create a high-performance RAID-controller that use IDE to simulate SCSI, that you want SCSI for your RAID to be able to have several requests active at the same time, and that the IDE-drives normally are low-end drives physically compared to the SCSI-drives.
