I want to buy an internal harddrive (1TB) and an external enclosure (since I understood that it might be better that way, since the external hard drives that are available today, for some reason are less reliable)
but where I live there aren't many options as to chose an external enclosure,
I can buy this vantec one for exampel:
They are all aluminum so that's good. I'd read the customer reviews of each device and see how they fair. I wouldn't worry to much about eSATA with USB3.0 coming out. I've been satisfied with USB2.0 so far. Yes transfers of a large number of files (1000+ at 4gb+) takes forever but I just walk away and have a cup of coffee or something.
