OK, now i have two MBP sitting here, I have notice there's a performance different between the H+L Data Storage multi-drive and my original MBP that has a Matshita SuperDrive. The later seems to be faster and quieter though both drives specs are the same. Has anyone else notice this? Out of curiosity, what drives are installed in your machine? And how reliable is it for you, in terms of media used, coasters created?
