Why did IDE (and USB and SATA) become "standard" for the desktop? Intel choose to integrate it into the motherboard chipset, I think way back with the i440FX. All discussions about merit, quality, performance and other stuff aside, when Intel backs something, 90% of the time it becomes "the" standard (10% of the time accounts for RAMBUS

"Typical" SCSI does have benefits, such as lower access times and capability for more drives, however IDE standards have done a good job in keeping up with controller transfer rates and current drives have reasonable STR compared to SCSI - and of course the price/performance/capacity of EIDE can't be beat.
Perhaps it really isn't the
interface that makes SCSI, more that it is the
class of device. Up next? SAS, which is somewhat compatible with SATA. Once they use the same interface, what's superior about SCSI? The "class of device" meaning longer warranties, rated for sustained 24/7 duty cycles, lower latencies, capable of more drives... that's what it's been all along.
