I usually don't like writing reviews cos there are always pseudo techies somewhere telling people what to do and what to do. Funny enough, 90 percent of them leave reviews that either ruin a product's rating or ruin other people takes or experiences with them. Fortunately, I'm a high IT Systems Admin with a dozen of years experience under my belt, so I move through these chuff deemed helpful reviews. I bought 8 of these drive for my FreeNAS build and they have been perfect so far. Shucking them was very easy and I can honestly say the cases or enclosures are all perfectly intact with not even a single scratch on them. All I used was a simple flat head screw driver, some patience and a sprinkle of common sense. There's no need to force these puppies open. Took less than a minute to open each enclosure. I kept all the internals, closed it back up and boxed for potential warranty purposes. See below for photos. In terms of whether you'd find Red NAS 256mb drives in these, that possible as well. I got 8 of them; 2 and then 6 from two different locations. All Reds! The secret is in the serial numbers. Hopefully you can pick that up from my photos as well. These work very well and have been working for me for almost 6 months now. They start off slightly noisy, but as you start to fill them up they really do quiet down. I have 8 in my case and I hear my low rpm fans before I hear these puppies. I am running all eight drives off of a P20 IT Mode flashed IBM ServeRAID M1015 card. Average read speed for all eight drives at full throttle is around 800mb/s and works superbly in FreeNAS 9.3+ in raid z configuration. The total raw storage of 58TB (not 64) is used to house my Plex library. I keep my OS and Plex Jail on separate raided SSDs for performance and redundancy purposes. My FreeNAS OS runs on two raided 60GB Corsair Force GTs and the Plex Jail runs off of two raided 180GB Intel SSDs. The OS runs pretty fast and Plex does all its work without having to access the Red drives for nothing but library updates and video playback. My server motherboard houses three Intel Pro 1000 gigabit NICs, but I added another Intel quad i350 NIC with LACP enabled for a more balance network access of the drives. I even added a HDHomerun Quattro for Live TV and DVR option to my Plex server thanks to the tons of space these drives provide. My Plex library is almost 22TB large and comprises of over 3000 movies in 1080P or better, tons of collected TV Drama, Anime and Sitcoms. Friends and family here and abroad stream videos off it and these drives handles them all flawlessly. Multiple users usually streaming at a time as well. They are great and haven't broken a sweat. Only issues I had was some data corruption when my server lost power during a rainstorm while data was being written to the drives. A quick zpool scrub was all I needed to fix that. They are flawless, trust me. I need to buy 2 more when they get back on sale. I guess I could only add 2 photos max. LOL
