I find SATA far better almost in every way, but there are some flaws.
I find SATA far more likely to breakdown as the cable connections are flimsy compared to IDE, you only have to sneaze and the SATA cable falls out of it’s socket.
I find IDE a lot more rugged and reliable although far slower with data transference. My parents have a SATA hard drive and they have had nothing but problems with it and often it’s due to loose wiring.
IDE despite being old-fashioned (out of date) does have some advantages in reliability. SATA will soon replace the IDE HDDs, which is already happening, I just hope that connections would be more modified to be more reliable.
