So i just got my brand new macbook pro 15" 2.66 ghz i7, 4 gb ram, high res, 500 gb 7200 rpm hdd, and I am ecstatic this computer is SO fast it blow my mind all over the table, the question i have is about the SD card slot, is there limit on data transfer for the SD card slot or is it limited by the speed of the card? i have a 16 GB sandisk extreme 2 that transfers @ 15 mb/s and a 4 GB sandisk extreme 3 that transfers @ 30 mb/s so can i transfer at those speeds or is it buffered? i tried importing 1 GB i had on the slower card and it transferred extremely fast but i cannot remember how fast the usb 2.0 was because i never really paid much attention. Thanks i love this computer!!!!
