I am normal Macbook pro user and I have some doubts and I want to clear them through this thread. I came to know about External GoFlex drivers from Seagate website and they also said that they also give 1.5 TB. Seagate is also giving SATA connection which we can use with GoFlex cables USB 3.0 and Firewires etc. I think so it is The First 1.5TB Portable External Hard Drive Is USB 3.0 and From Seagate. My doubt is about to use this external hard drive inside my Macbook pro as like basic hard drive. Mine is normal 2,5” port drive and should I go for this experiment is anyone here who have done this test on his mac system please inform me.
