I have been looking around at hard drives & enclosures. I read that it is more economical to get bare hard drives, & swap them out in enclosures. But I am finding that as capacities of hard drives increase, my enclosures that I have are already obsolete, I see 4tb hard drives now, & all my enclosures are rated to support up to 2tb. I dont want to have to keep buying new enclosures to accommodate bigger capacity hard drives almost every year, or at least for the enclosures to last more than just a couple of years. On the other hand I can just buy a whole external hard drive in an enclosure ready made, & it seems cheaper this way.
