So, I just did a search and found nothing but an extremely lengthy thread that makes no sense and doesn't even answer the question. I just want a simple answer here: I have a new 17" '09 uMBP. I want to use my eSata external hard drives. What expresscard adapter should I buy? I was transferring stuff over via USB and was horrified: 25 minutes to transfer 20 gigs of pictures! 20 gigs should take no more than 5, maybe 10 minutes tops over eSata (as it did on my old laptop). So which eSata-Expresscard actually works for the uMBP's? Thanks.
