Hello, all. I am looking into saving up for a nice 3-4tb thunderbolt external hard drive for my new iMac that had a 256gb SSD. I plan to have the OS and Apps on the SD while the external will have my songs I record (logic), videos I edit (final cut), photo library, and large iTunes library. I will later buy additional thunderbolt drives and daisy chain when I need to. My question is on speed and reliability. I have mostly hears great things about Promise and G-Technology (G-Raid), mixed reviews on Dorbos and Lacies, and mostly negative things about Western Digital. Haven't heard much about seagate. At this point, I am most likely leaning towards the G-Technology G-Raid with 4tb. Can anyone with more experience give me some input? Thank you.
