Summary: Bought one ST4000NM0033-9ZM170 from B&H. Noticeable vibration. Hot, 37C under random I/O. For comparison, other consumer grade drives with random I/O under the same environment: WD Red 3TB WD30EFRX-68AX9N0 (5400rpm): 28C WD Red 3TB WD30EFRX-68EUZN0 (5400rpm): 28C Hitachi 750GB HDS721075KLA330...
Summary: It came with full 5 year Warranty. Packaging / protection was not bad. (Checkout all the sellers before you make the purchase) It is fast, working great so far. Will update later as I use this drive more.

Summary: Using these in a nas array and so far so good. No sure how much detail you can get into on hard drives these days but the performance seems really good. 4TB are still a bit pricey but overall a good product.
