When you press the eject button.. does it open both superdrives? Or is there a way to control individual ones to open?
I believe it's Eject to do the one, and then Opt+Eject to do the other.
Are the cables for the 2nd optical drives SATA?
No, but there are free SATA ports on the logic board that you can use if you have a SATA cable.
If you use the SATA port on the logic board.. wouldnt that steal part of the bandwidth from your 4 hdd?
