Hi all! Can someone please help because I know nothing about eSATA, except that it's not the same Plug'n'Play type interface as USB 2 and FireWire 400/800 are. Or can I just get any one of them and be fine? I've got an eSATA cable and an external hard drive from Hitachi with the eSATA interface, but I still need to find a card for the Express 34 slot that's found on the 2008, 2009, 2010 and 2011 17" MacBook Pro's, or any previous MBP with an eSATA interface. Thank you very much in advance!
