There are no distinct advantages to SATA that I can see.
scsi is faster (its designed that way) but as a result, more expensive. SCSI
uses intelligent controllers, thus the cpu never has to be involved in such
operations
IDE is a "throw away" technology. when it dies, pulls the old one and toss in
a new one (hence its cheap). only major problem with IDE is that the CPU gets
involved in controller operations, thus there is always a certain amount of
overhead (especially with high I/O).
Personally, I'd rather see SCSI make a comeback and be just as affordable as
IDE (don't think that will happen as the server market will make sure it
doesn't).
meanwhile, the ever present hunt for "cheap" technology goes on.
