So I do shuck these drives. I don't use them in their external enclosures. So if you want to know how they perform as external drives, I unfortunately can't offer you any assistance there. But if you remove the hard drives from these enclosures for internal use. I can help you.
These drives are amazing. I've been buying them when they go on sell from Amazon and other retailers. I've purchased about five total and so far they have all been Barracuda or Barracuda Pro's. I also test the drive before I shuck it (remove it from it's enclosure).. and have yet to get one DOA. They've been going very strong in my unraid server which primarily runs Plex, but I also use it with programs like handbrake. So they do receive a constant amount of data being written and modified on them. They stay cool. They run quiet. And lastly, they run perfect. Will continue to buy these for all of my large storage needs.
