What's more, IDE suffers from not having TCQ (well, AFAIK, ATA 100 will have)
and cannot oper in disconnected mode. Not to mention that IDE or EIDE (ie, IDE
+ ATAPI) is limited in speed by the peripheral which has the lower command
input rate.
SCSI is far from being replaced anytime soon. You want performance, take SCSI.
