WD Red Pro 18TB

I can't put in words how great these Red Pro drives are. This is my second Red Pro drive adding to my Alienware R8. I have been building my home library for streaming. My friends were all saying to get a Synology NAS system but I had a perfectly good R8 that I wasn't using for gaming or anything so I thought why not use it. The area I live in (near Chattanooga, TN) is where the EPB Electrical Utility has the GIG Fiber available to all of it's customers. I know my i9 processor might be overkill but these drives are awesome. The Plex software has not had 1 glitch in retrieving anything on my library. I have put this thing to the test with multiple streams and the drives have been flawless!

Installed in UGreen NAS and working great.

So far so good. A little noisy but if that's what concerns you about a hard drive, I suggest a priority shift.
