E-IDE (ATAPI) or USB

[mark4man]

Folks,

Having found an external Plextor Premium-U, which will be used to burn pre-master audio CD's to be sent to the replication house for mass production...

...I understand that most CD-RW's are mfg.'s as E-IDE; & if packaged as external by the mfg., a Bridge Chip is used to adapt the interface (ATA-2 > USB.)

So, my question is:

Am I going to get as accurate a burn utilizing USB, as I would from an internal drive hooked up to the IDE ribbon cable in the tower?

Is the data that's transferred identical...or is it converted somehow?

Thanks,
