Anyone remember the NEC 4x and 6x 4 CD changers that were the same size as standard drives? Anyone also remember how bad they were since without any onboard cache, anything you did made the drive cycle through all 4 discs to relearn what they were? It was a great idea destroyed by bad design.
What was useless for a reader would be fantastic for a writer even if it were just as badly designed. I'd love to have a 4 CD changer writer. I'd load up 4 blanks, tell the software the next 4 CD's I want to write, and have it go to town. All you would need is 3 of these and you could hammer out 12 CD's at a time unattended.
