I once read a story where a mastering engineer claimed he could tell whether it was a Maxtor or a Western Digital HD attached to his DAW. He was probably making a joke. The key factors with drives is the interface and platter rotation speed. Any recent vintage HD with ATA, IDE, Firewire, USB 2 or SCSI and 7200 rpm platters will have no problems with the playback of two channel audio.
As far as optical vs. non-optical, my experience is that balanced AES/EBU is definitely superior to optical.
Did you have Apple replace the dead iPod?
