   IDE was designed to be nothing more than a cheap way of connecting one or
perhaps two drives to a motherboard, so seek and access delays were ignored.
It may or may not be true that recent IDE drives are as well designed and
assembled as SCSI, performance figures for a single IDE drive per cable
could be as good as SCSI, IDE drives did benefit from both greater
production quantities and competition, but multiple drives using wide SCSI,
fibre, or hopefully SATA, should perform much better. The current standard
SCSI naming system has nothing to do with SCSI addressing, and the system
must be able to locate individual drives correctly, so adjusting the naming
policy should not present too many problems.
