I have the new 15 in MBP and bought a e-sata express card from OWC which is the Apiotek Extreme Dual e-sata http://eshop.macsales.com/item/Apiotek/EC0003D/. At first it could not be seen so I went to there site and downloaded the driver for it and got several grey screens of death kernel panics. I know the Sonnet Tempo SATA Pro ExpressCard/34 is supposed to work on the new unibody but after all that I bought to get this system up to the speed I need, was trying to avoid another 280 dollars and want another 4gb Ram chip more. http://eshop.macsales.com/item/Sonnet Technology/SATAIIPROE34/ I am only running one external drive like this for PS scratch, OS backup and a working drive that is partitioned in 3 sections. Wondering if there is another express card that is working in the new 15 in 2.93 without any issues.
